Linus Torvalds f5b7769eb0 Revert "debugfs: inode: debugfs_create_dir uses mode permission from parent" 
This reverts commit 95cde3c599.

The commit had good intentions, but it breaks kvm-tool and qemu-kvm.

With it in place, "lkvm run" just fails with

  Error: KVM_CREATE_VM ioctl
  Warning: Failed init: kvm__init

which isn't a wonderful error message, but bisection pinpointed the
problematic commit.

The problem is almost certainly due to the special kvm debugfs entries
created dynamically by kvm under /sys/kernel/debug/kvm/.  See
kvm_create_vm_debugfs()

Linus Torvalds dbee3d0245 KVM: x86: VMX: fix build without hyper-v 
Commit ceef7d10df ("KVM: x86: VMX: hyper-v: Enlightened MSR-Bitmap
support") broke the build with Hyper-V disabled, because it accesses
ms_hyperv.nested_features without checking if that exists.

This is the quick-and-hacky build fix.

I suspect the proper fix is to replace the

    static_branch_unlikely(&enable_evmcs)

tests with an inline helper function that also checks that CONFIG_HYPERV
is enabled, since without that, enable_evmcs makes no sense.

But I want a working build environment first and foremost, and I'm upset
this slipped through in the first place.  My primary build tests missed
it because I tend to build with everything enabled, but it should have
been caught in the kvm tree.

Linus Torvalds b08fc5277a Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux 
Pull more overflow updates from Kees Cook:
 "The rest of the overflow changes for v4.18-rc1.

  This includes the explicit overflow fixes from Silvio, further
  struct_size() conversions from Matthew, and a bug fix from Dan.

  But the bulk of it is the treewide conversions to use either the
  2-factor argument allocators (e.g. kmalloc(a * b, ...) into
  kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
  b) into vmalloc(array_size(a, b)).

  Coccinelle was fighting me on several fronts, so I've done a bunch of
  manual whitespace updates in the patches as well.

  Summary:

   - Error path bug fix for overflow tests (Dan)

   - Additional struct_size() conversions (Matthew, Kees)

   - Explicitly reported overflow fixes (Silvio, Kees)

   - Add missing kvcalloc() function (Kees)

   - Treewide conversions of allocators to use either 2-factor argument
     variant when available, or array_size() and array3_size() as needed
     (Kees)"

Pull more xfs updates from Darrick Wong:
 "Here's the second round of patches for XFS for 4.18. Most of the

Pull ARM SoC device tree updates from Olof Johansson:
 "As always, a large number of DT updates. Too many to enumerate them
  all, but at a glance:

  New SoCs introduced in this release:

   - Amlogic:
      + Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some
        set top boxes and other products.

   - Mediatek:
      + MT7623A, which is a flavor of the MT7623 family with other
        on-chip ethernet options.

   - Qualcomm:
      + SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
        (Cortex-A75/A55 derivative) SoC that's one of the current
        high-end mobile SoCs.

        It's great to see mainline support for it. So far, you can't do
        much with it, since a lot of peripherals are not yet in the DTs
        but driver support for USB, GPU and other pieces are starting to
        trickle in. This might end up being a well-supported SoC
        upstream if the momentum keeps up.

   - Renesas:
      + R8A77990, a.k.a R-Car E3, a new automotive
        entertainment-targeted SoC. Currently only one Cortex-A53 CPU is
        enabled, we are eagerly awaiting more. So far, basic drivers
        such as serial, gpios, PMU and ethernet are enabled.
      + R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
        GPU. Same here, basic set of drivers such as serial, gpios and
        ethernet enabled, and SMP support is also forthcoming.

   - STMicroelectronics:
      + STM32F469, very similar tih STM32F429 but with display support

  Enhancements to SoCs/platforms (DTS contents, some driver portions
  might not be in yet):
   - Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
   - Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets
   - Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces
   - Marvell Berlin2CD: SMP support, thermal sensors
   - Mediatek MT7623: Highspeed DMA, audio support
   - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support
   - Renesas: Watchdog and PMU support across many platforms
   - Rockchip RK3399: USB3 OTG support
   - Samsung Exynos: Audio-over-HDMI on Odroid X/X2/U3
   - STMicro STM32: Lots of peripherals added to STM32MP175C
   - Uniphier: Ethernet support

  New boards:
   - Allwinner A20: Olimex A20-SOM-EVB-eMMC variant
   - Allwinner H2+: Libre Computer ALL-H3-CC (h2+ version)

 "Here are the main updates for SoC support (besides DT additions) for
  ARM 32- and 64-bit platforms. The branch also contains defconfig
  updates to turn on drivers and options as needed on the various

  The largest parts of the delta are from cleanups moving platform data
  and board file setup of TI platforms to ti-sysc bus drivers. There are
  also some sweeping changes of eeprom and nand setup on Davinci, i.MX
  and other platforms.

  Samsung is removing support for Exynos5440, which was an oddball SoC
  that hasn't been seen much use in designs.

  Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).

Linus Torvalds e16c4790de Revert "iommu/amd_iommu: Use CONFIG_DMA_DIRECT_OPS=y and dma_direct_{alloc,free}()" 
This reverts commit b468620f2a.

It turns out that this broke drm on AMD platforms. Quoting Gabriel C:
 "I can confirm reverting b468620f2a fixes
  that issue for me.

  The GPU is working fine with SME enabled.

  Now with working GPU :) I can also confirm performance is back to
  normal without doing any other workarounds"

Christan König analyzed it partially:
 "As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs()
  in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled"

and Christoph Hellwig responded:
 "I think the prime issue is that dma_direct_alloc respects the dma
  mask. Which we don't need if actually using the iommu. This would be
  mostly harmless exept for the the SEV bit high in the address that
  makes the checks fail.

  For now I'd say revert this commit for 4.17/4.18-rc and I'll look into
  addressing these issues properly"

to be fixed, let's see if anybody even uses it, and mark it broken.  It
may be that we can just remove the code entirely.

Linus Torvalds d54d35c501 Merge tag 'f2fs-for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs 
Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've mainly focused on discard, aka unmap, control
  along with fstrim for Android-specific usage model. In addition, we've
  fixed writepage flow which returned EAGAIN previously resulting in EIO
  of fsync(2) due to mapping's error state. In order to avoid old MM bug
  [1], we decided not to use __GFP_ZERO for the mapping for node and
  meta page caches. As always, we've cleaned up many places for future
  fsverity and symbol conflicts.

  Enhancements:
   - do discard/fstrim in lower priority considering fs utilization
   - split large discard commands into smaller ones for better responsiveness
   - add more sanity checks to address syzbot reports
   - add a mount option, fsync_mode=nobarrier, which can reduce # of cache flushes
   - clean up symbol namespace with modified function names
   - be strict on block allocation and IO control in corner cases

  Bug fixes:
   - don't use __GFP_ZERO for mappings
   - fix error reports in writepage to avoid fsync() failure
   - avoid selinux denial on CAP_RESOURCE on resgid/resuid
   - fix some subtle race conditions in GC/atomic writes/shutdown
   - fix overflow bugs in sanity_check_raw_super
   - fix missing bits on get_flags

  Clean-ups:
   - prepare the generic flow for future fsverity integration
   - fix some broken coding standard"

Linus Torvalds a2225d931f autofs: remove left-over autofs4 stubs 
There's no need to retain the fs/autofs4 directory for backward
compatibility.

Adding an AUTOFS4_FS fragment to the autofs Kconfig and a module alias
for autofs4 is sufficient for almost all cases. Not keeping fs/autofs4
remnants will prevent "insmod <path>/autofs4/autofs4.ko" from working
but this shouldn't be used in automation scripts rather than
modprobe(8).

There were some comments about things to look out for with the module
rename in the fs/autofs4/Kconfig that is removed by this patch, see the
commit patch if you are interested.

One potential problem with this change is that when the
fs/autofs/Kconfig fragment for AUTOFS4_FS is removed any AUTOFS4_FS
entries will be removed from the kernel config, resulting in no autofs
file system being built if there is no AUTOFS_FS entry also.

This would have also happened if the fs/autofs4 remnants had remained
and is most likely to be a problem with automated builds.

Please check your build configurations before the removal which will
occur after the next couple of kernel releases.

Pull x86 updates and fixes from Thomas Gleixner:

 - Fix the (late) fallout from the vector management rework causing
   hlist corruption and irq descriptor reference leaks caused by a
   missing sanity check.

   The straight forward fix triggered another long standing issue to
   surface. The pre rework code hid the issue due to being way slower,
   but now the chance that user space sees an EBUSY error return when
   updating irq affinities is way higher, though quite a bunch of
   userspace tools do not handle it properly despite the fact that EBUSY
   could be returned for at least 10 years.

   It turned out that the EBUSY return can be avoided completely by
   utilizing the existing delayed affinity update mechanism for irq
   remapped scenarios as well. That's a bit more error handling in the
   kernel, but avoids fruitless fingerpointing discussions with tool
   developers.

 - Decouple PHYSICAL_MASK from AMD SME as its going to be required for
   the upcoming Intel memory encryption support as well.

 - Handle legacy device ACPI detection properly for newer platforms

 - Fix the wrong argument ordering in the vector allocation tracepoint

 - Simplify the IDT setup code for the APIC=n case

 - Use the proper string helpers in the MTRR code

 - Remove a stale unused VDSO source file

 - Convert the microcode update lock to a raw spinlock as its used in
   atomic context.

     wasn't allocated, print a debug message for such cases (Arnaldo
     Carvalho de Melo)

   - Fix symbol and object code resolution for vdso32 and vdsox32
     (Adrian Hunter)

   - No need to check for null when passing pointers to foo__get() style
     refcount grabbing helpers, just like in the kernel and with free(),
     its safe to pass a NULL pointer to avoid having to check it before
     each and every foo__get() call (Arnaldo Carvalho de Melo)

   - Remove some dead code (quote.[ch]) (Arnaldo Carvalho de Melo)

   - Remove some needless globals, making them local (Arnaldo Carvalho

   - Reduce usage of symbol_conf.use_callchain, using other means of
     finding out if callchains are in use or available for specific
     events, as we evolved this codebase to allow requesting callchains
     for just a subset of the monitored events. In time it will help
     polish recording and showing mixed sets accross the various tools:

        perf record -e cycles/call-graph=fp/,cache-misses/call-graph=dwarf/,instructions'

Linus Torvalds 3ca24ce9ff Merge branch 'proc-cmdline' 
Merge proc_cmdline simplifications.

This re-writes the get_mm_cmdline() logic to be rather simpler than it
used to be, and makes the semantics for "cmdline goes past the end of
the original area" more natural.

You _can_ use prctl(PR_SET_MM) to just point your command line somewhere
else entirely, but the traditional model is to just edit things in place
and that still needs to continue to work.  At least this way the code
makes some sense.

Pull clk updates from Stephen Boyd:
 "This time we have a good set of changes to the core framework that do
  some general cleanups, but nothing too major. The majority of the diff
  goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is
  introduced for Actions Semi so it takes up some lines to add all the
  different types, and the Qualcomm diff is there because we add support
  for two SoCs and it's quite a bit of data.

  Otherwise the big driver updates are on TI Davinci and Amlogic
  platforms. And then the long tail of driver updates for various fixes
  and stuff follows after that.

  Core:
   - debugfs cleanups removing error checking and an unused provider API
   - Removal of a clk init typedef that isn't used
   - Usage of match_string() to simplify parent string name matching
   - OF clk helpers moved to their own file (linux/of_clk.h)
   - Make clk warnings more readable across kernel versions

  New Drivers:
   - Qualcomm SDM845 GCC and Video clk controllers
   - Qualcomm MSM8998 GCC
   - Actions Semi S900 SoC support
   - Nuvoton npcm750 microcontroller clks
   - Amlogic axg AO clock controller

  Removed Drivers:
   - Deprecated Rockchip clk-gate driver

  Updates:
   - debugfs functions stopped checking return values
   - Support for the MSIOF module clocks on Rensas R-Car M3-N
   - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
   - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
   - Berlin and Amlogic SPDX tagging
   - Usage of of_clk_get_parent_count() in more places

Pull staging/IIO updates from Greg KH:
 "Here is the big staging and IIO driver update for 4.18-rc1.

  It was delayed as I wanted to make sure the final driver deletions did
  not cause any major merge issues, and all now looks good.

  There are a lot of patches here, just over 1000. The diffstat summary
  shows the major changes here:

	1007 files changed, 16828 insertions(+), 227770 deletions(-)

  Because of this, we might be close to shrinking the overall kernel
  source code size for two releases in a row.

  There was loads of work in this release cycle, primarily:

   - tons of ks7010 driver cleanups

   - lots of mt7621 driver fixes and cleanups

   - most driver cleanups

   - wilc1000 fixes and cleanups

   - lots and lots of IIO driver cleanups and new additions

   - debugfs cleanups for all staging drivers

   - lots of other staging driver cleanups and fixes, the shortlog has
     the full details.

  but the big user-visable things here are the removal of 3 chunks of
  code:

   - ncpfs and ipx were removed on schedule, no one has cared about this
     code since it moved to staging last year, and if it needs to come
     back, it can be reverted.

   - lustre file system is removed.

     I've ranted at the lustre developers about once a year for the past
     5 years, with no real forward progress at all to clean things up
     and get the code into the "real" part of the kernel.

     Given that the lustre developers continue to work on an external
     tree and try to port those changes to the in-kernel tree every once
     in a while, this whole thing really really is not working out at
     all. So I'm deleting it so that the developers can spend the time
     working in their out-of-tree location and get things cleaned up
     properly to get merged into the tree correctly at a later date.

  Because of these file removals, you will have merge issues on some of
  these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
  atomisp driver). Just delete those files, it's a simple merge :)

  All of this has been in linux-next for a while with no reported
  problems"

Pull libnvdimm updates from Dan Williams:
 "This adds a user for the new 'bytes-remaining' updates to
  memcpy_mcsafe() that you already received through Ingo via the
  x86-dax- for-linus pull.

  Not included here, but still targeting this cycle, is support for
  handling memory media errors (poison) consumed via userspace dax
  mappings.

  Summary:

   - DAX broke a fundamental assumption of truncate of file mapped
     pages. The truncate path assumed that it is safe to disconnect a
     pinned page from a file and let the filesystem reclaim the physical
     block. With DAX the page is equivalent to the filesystem block.
     Introduce dax_layout_busy_page() to enable filesystems to wait for
     pinned DAX pages to be released. Without this wait a filesystem
     could allocate blocks under active device-DMA to a new file.

   - DAX arranges for the block layer to be bypassed and uses
     dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
     However, the memcpy_mcsafe() facility is available through the pmem
     block driver. In order to safely handle media errors, via the DAX
     block-layer bypass, introduce copy_to_iter_mcsafe().

   - Fix cache management policy relative to the ACPI NFIT Platform
     Capabilities Structure to properly elide cache flushes when they
     are not necessary. The table indicates whether CPU caches are
     power-fail protected. Clarify that a deep flush is always performed
     on REQ_{FUA,PREFLUSH} requests"

  We also have the start of updates to use coupled regulators from

Linus Torvalds 410feb75de Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux 
Pull arm64 updates from Catalin Marinas:
 "Apart from the core arm64 and perf changes, the Spectre v4 mitigation
  touches the arm KVM code and the ACPI PPTT support touches drivers/
  (acpi and cacheinfo). I should have the maintainers' acks in place.

  Summary:

   - Spectre v4 mitigation (Speculative Store Bypass Disable) support
     for arm64 using SMC firmware call to set a hardware chicken bit

   - ACPI PPTT (Processor Properties Topology Table) parsing support and
     enable the feature for arm64

   - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
     primary motivation is Scalable Vector Extensions which requires
     more space on the signal frame than the currently defined
     MINSIGSTKSZ

   - ARM perf patches: allow building arm-cci as module, demote
     dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous
     cleanups

   - cmpwait() WFE optimisation to avoid some spurious wakeups

   - L1_CACHE_BYTES reverted back to 64 (for performance reasons that
     have to do with some network allocations) while keeping
     ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual
     hardware Cache Writeback Granule

   - Turn LSE atomics on by default in Kconfig

   - Kernel fault reporting tidying

   - Some #include and miscellaneous cleanups"

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.18 development cycle.

  Core changes:

   - We have killed off VLA from the core library and all drivers.

     The background should be clear for everyone at this point:

        https://lwn.net/Articles/749064/

     Also I just don't like VLA's, kernel developers hate it when
     compilers do things behind their back. It's as simple as that.

     I'm sorry that they even slipped in to begin with. Kudos to Laura
     Abbott for exorcising them.

   - Support GPIO hogs in machines/board files.

  New drivers and chip support:

   - R-Car r8a77470 (RZ/G1C)

   - R-Car r8a77965 (M3-N)

   - R-Car r8a77990 (E3)

   - PCA953x driver improvements to accomodate more variants.

  Improvements and new features:

   - Support one interrupt per line on port A in the DesignWare dwapb
     driver.

  Misc:

   - Random cleanups, right header files in the drivers, some size
     optimizations etc"

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for v4.18.

  No core changes this time! Just a calm all-over-the-place drivers,
  updates and fixes cycle as it seems.

  New drivers/subdrivers:

   - Actions Semiconductor S900 driver with more Actions variants for
     S700, S500 in the pipe. Also generic GPIO support on top of the
     same driver and IRQ support is in the pipe.

   - Renesas r8a77470 PFC support.

   - Renesas r8a77990 PFC support.

   - Allwinner Sunxi H6 R_PIO support.

Pull rdma updates from Jason Gunthorpe:
 "This has been a quiet cycle for RDMA, the big bulk is the usual
  smallish driver updates and bug fixes. About four new uAPI related
  things. Not as much Szykaller patches this time, the bugs it finds are
  getting harder to fix.

  Summary:

   - More work cleaning up the RDMA CM code

   - Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns,
     i40iw, iw_cxgb4, mlx5, rxe

   - Driver specific resource tracking and reporting via netlink

   - Continued work for name space support from Parav

   - MPLS support for the verbs flow steering uAPI

   - A few tricky IPoIB fixes improving robustness

   - HFI1 driver support for the '16B' management packet format

   - Some auditing to not print kernel pointers via %llx or similar

   - Mark the entire 'UCM' user-space interface as BROKEN with the
     intent to remove it entirely. The user space side of this was long
     ago replaced with RDMA-CM and syzkaller is finding bugs in the
     residual UCM interface nobody wishes to fix because nobody uses it.

   - Purge more bogus BUG_ON's from Leon

   - 'flow counters' verbs uAPI

   - T10 fixups for iser/isert, these are Acked by Martin but going
     through the RDMA tree due to dependencies"

Linus Torvalds 2857676045 Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux 
Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

  Summary:

   - Introduce arithmetic overflow test helper functions (Rasmus)

   - Use overflow helpers in 2-factor allocators (Kees, Rasmus)

   - Introduce overflow test module (Rasmus, Kees)

   - Introduce saturating size helper functions (Matthew, Kees)

Pull audit updates from Paul Moore:
 "Another reasonable chunk of audit changes for v4.18, thirteen patches
  in total.

  The thirteen patches can mostly be broken down into one of four
  categories: general bug fixes, accessor functions for audit state
  stored in the task_struct, negative filter matches on executable
  names, and extending the (relatively) new seccomp logging knobs to the
  audit subsystem.

  The main driver for the accessor functions from Richard are the
  changes we're working on to associate audit events with containers,
  but I think they have some standalone value too so I figured it would
  be good to get them in now.

  The seccomp/audit patches from Tyler apply the seccomp logging
  improvements from a few releases ago to audit's seccomp logging;
  starting with this patchset the changes in
  /proc/sys/kernel/seccomp/actions_logged should apply to both the
  standard kernel logging and audit.

Linus Torvalds af6c5d5e01 Merge branch 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq 
Pull workqueue updates from Tejun Heo:

 - make kworkers report the workqueue it is executing or has executed
   most recently in /proc/PID/comm (so they show up in ps/top)

 - CONFIG_SMP shuffle to move stuff which isn't necessary for UP builds
   inside CONFIG_SMP.

Linus Torvalds 9f25a8da42 Merge branch 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup 
Pull cgroup updates from Tejun Heo:

 - For cpustat, cgroup has a percpu hierarchical stat mechanism which
   propagates up the hierarchy lazily.

   This contains commits to factor out and generalize the mechanism so
   that it can be used for other cgroup stats too.

   The original intention was to update memcg stats to use it but memcg
   went for a different approach, so still the only user is cpustat. The
   factoring out and generalization still make sense and it's likely
   that this can be used for other purposes in the future.

 - cgroup uses kernfs_notify() (which uses fsnotify()) to inform user
   space of certain events. A rate limiting mechanism is added.

 - Other misc changes.

* 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
  cgroup: css_set_lock should nest inside tasklist_lock
  rdmacg: Convert to use match_string() helper

  cgroup: Add memory barriers to plug cgroup_rstat_updated() race window

Linus Torvalds 0bbddb8cbe Merge branch 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata 
Pull libata updates from Tejun Heo:

 - libata has always been limiting the maximum queue depth to 31, with
   one entry set aside mostly for historical reasons. This didn't use to
   make much difference but Jens found out that modern hard drives can
   actually perform measurably better with the extra one queue depth.
   Jens updated libata core so that it can make use of full 32 queue
   depth

 - Damien updated command retry logic in error handling so that it
   doesn't unnecessarily retry when upper layer (SCSI) is gonna handle
   them

 - A couple misc changes

* 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  sata_fsl: use the right type for tag bitshift
  ahci: enable full queue depth of 32
  libata: don't clamp queue depth to ATA_MAX_QUEUE - 1
  libata: add extra internal command
  sata_nv: set host can_queue count appropriately

  libata: use ata_tag_internal() consistently

  libata: introduce notion of separate hardware tags
