Merge tag 'libnvdimm-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"This update has successfully completed a 0day-kbuild run and has
appeared in a linux-next release. The changes outside of the typical
drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
the introduction of ZONE_DEVICE + devm_memremap_pages().
Summary:
- Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
mechanism for adding device-driver-discovered memory regions to the
kernel's direct map.
This facility is used by the pmem driver to enable pfn_to_page()
operations on the page frames returned by DAX ('direct_access' in
'struct block_device_operations').
For now, the 'memmap' allocation for these "device" pages comes
from "System RAM". Support for allocating the memmap from device
memory will arrive in a later kernel.
- Introduce memremap() to replace usages of ioremap_cache() and
ioremap_wt(). memremap() drops the __iomem annotation for these
mappings to memory that do not have i/o side effects. The
replacement of ioremap_cache() with memremap() is limited to the
pmem driver to ease merging the api change in v4.3.
Completion of the conversion is targeted for v4.4.
- Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
driver, update the VFS DAX implementation and PMEM api to provide
persistence guarantees for kernel operations on a DAX mapping.
- Convert the ACPI NFIT 'BLK' driver to map the block apertures as
cacheable to improve performance.
- Miscellaneous updates and fixes to libnvdimm including support for
issuing "address range scrub" commands, clarifying the optimal
'sector size' of pmem devices, a clarification of the usage of the
ACPI '_STA' (status) property for DIMM devices, and other minor
fixes"

xen: Use correctly the Xen memory terminologies
Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN is meant, I suspect this is because the first support for Xen was for PV. This resulted in some misimplementation of helpers on ARM and confused developers about the expected behavior. For instance, with pfn_to_mfn, we expect to get an MFN based on the name. Although, if we look at the implementation on x86, it's returning a GFN. For clarity and avoid new confusion, replace any reference to mfn with gfn in any helpers used by PV drivers. The x86 code will still keep some reference of pfn_to_mfn which may be used by all kind of guests No changes as been made in the hypercall field, even though they may be invalid, in order to keep the same as the defintion in xen repo. Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a name to close to the KVM function gfn_to_page. Take also the opportunity to simplify simple construction such as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean up will come in follow-up patches.

DT bindings and support for them among other things.
We have a few updates of the generic power domains framework and a
reorganization of the ACPI device enumeration code and bus type
operations.

Merge tag 'char-misc-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver patches from Greg KH: "Here's the "big" char/misc driver update for 4.3-rc1. Not much really interesting here, just a number of little changes all over the place, and some nice consolidation of the nvmem drivers to a common framework. As usual, the mei drivers stand out as the largest "churn" to handle new devices and features in their hardware. All have been in linux-next for a while with no issues" * tag 'char-misc-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (136 commits) auxdisplay: ks0108: initialize local parport variable extcon: palmas: Fix build break due to devm_gpiod_get_optional API change extcon: palmas: Support GPIO based USB ID detection extcon: Fix signedness bugs about break error handling extcon: Drop owner assignment from i2c_driver extcon: arizona: Simplify pdata symantics for micd_dbtime extcon: arizona: Declare 3-pole jack if we detect open circuit on mic extcon: Add exception handling to prevent the NULL pointer access extcon: arizona: Ensure variables are set for headphone detection extcon: arizona: Use gpiod inteface to handle micd_pol_gpio gpio extcon: arizona: Add basic microphone detection DT/ACPI bindings extcon: arizona: Update to use the new device properties API extcon: palmas: Remove the mutually_exclusive array extcon: Remove optional print_state() function pointer of struct extcon_dev extcon: Remove duplicate header file in extcon.h extcon: max77843: Clear IRQ bits state before request IRQ toshiba laptop: replace ioremap_cache with ioremap misc: eeprom: max6875: clean up max6875_read() misc: eeprom: clean up eeprom_read() misc: eeprom: 93xx46: clean up eeprom_93xx46_bin_read/write ... |

drivers/video/fbdev/vt8623fb: Use arch_phys_wc_add() and pci_iomap_wc()
This driver uses the same area for MTRR as for the ioremap().
Convert the driver from using the x86-specific MTRR code to the
architecture-agnostic arch_phys_wc_add(). It will avoid MTRRs if
write-combining is available. In order to take advantage of that
also ensure the ioremapped area is requested as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available.
b) Help bury MTRR code away, MTRR is architecture-specific and on
x86 it is being replaced by PAT.
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit

drivers/video/fbdev/gxt4500: Use pci_ioremap_wc_bar() to map framebuffer
The driver doesn't use mtrr_add() or arch_phys_wc_add() but
since we know the framebuffer is isolated already on an
ioremap() we can take advantage of write combining for
performance where possible.
In this case there are a few motivations for this:
a) Take advantage of PAT when available.
b) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
