Add an nfs4 operations count array to nfsd_stats structure. The count is
incremented in nfsd4_proc_compound() where all the operations are handled
by the nfsv4 server. This count of individual nfsv4 operations is also
entered into /proc filesystem.

Handle memory-mapped chips properly, needed for example on DECstations.
This support was in Linux 2.4 but for some reason got lost in 2.6. This
patch is taken directly from the linux-mips repository.

Fix some FRV arch compile errors, including:
(*) Marking nr_kernel_pages as __meminitdata so that references to it end up
being properly calculated rather than being assumed to be in the small
data section (and thus calculated wrt the GP register). Not doing this
causes the linker to emit errors as the offset is too big to fit into the
load instruction.
(*) Move pm_power_off into an unconditionally compiled .c file as it's now
unconditionally accessed.
(*) Declare frv_change_cmode() in a header file rather than in a .c file, and
declare it asmlinkage.

It turns out that there is a way to build a kernel with NUMA and no SMP.
In that case we are missing one definition __inc_zone_state.
Provide that missing __inc_zone_state.
(akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of
cpuless nodes. A NUMA system without SMP has a single processor but multiple
memory nodes. This used to work before on IA64 (wasn't aware of it, never seen
anyone with this kind of thing).")

We introduced 'io_sectors' recently so we could count the sectors that causes
io during resync separate from sectors which didn't cause IO - there can be a
difference if a bitmap is being used to accelerate resync.
However when a speed is reported, we find the number of sectors processed
recently by subtracting an oldish io_sectors count from a current
'curr_resync' count. This is wrong because curr_resync counts all sectors,
not just io sectors.
So, add a field to mddev to store the curren io_sectors separately from
curr_resync, and use that in the calculations.

screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h. This patches removes the include and modifies all users to
directly include screen_info.h. struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console. Note that this
patch touches every arch and I have no way of testing it. If there is a
mistake the worst thing that will happen is a compile error.

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

lockdep_map is embedded into every lock, which blows up data structure
sizes all around the kernel. Reduce the class-cache to be for the default
class only - that is used in 99.9% of the cases and even if we dont have a
class cached, the lookup in the class-hash is lockless.
This change reduces the per-lock dep_map overhead by 56 bytes on 64-bit
platforms and by 28 bytes on 32-bit platforms.

Certain subsystems in the stack (e.g., netfilter) can break the partial
checksum on GSO packets. Until they're fixed, this patch allows this to
work by recomputing the partial checksums through the GSO mechanism.
Once they've all been converted to update the partial checksum instead of
clearing it, this workaround can be removed.

This patch adds the wrapper function skb_is_gso which can be used instead
of directly testing skb_shinfo(skb)->gso_size. This makes things a little
nicer and allows us to change the primary key for indicating whether an skb
is GSO (if we ever want to do that).

Reimplement controller-wide PM. ata_host_set_suspend/resume() are
defined to suspend and resume a host_set. While suspended, EHs for
all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and
frozen.
Because SCSI device hotplug is done asynchronously against the rest of
libata EH and the same mutex is used when adding new device, suspend
cannot wait for hotplug to complete. So, if SCSI device hotplug is in
progress, suspend fails with -EBUSY.
In most cases, host_set resume is followed by device resume. As each
resume operation requires a reset, a single host_set-wide resume
operation may result in multiple resets. To avoid this, resume waits
upto 1 second giving PM to request resume for devices.
