It's carried in state->args->geo, so there's no need to duplicate it
and use more stack space than necessary.

We don't pass the xfs_da_args or the geometry all the way down to
the directory buffer logging code, hence we have to use
mp->m_dir_geo here. Fix this to use the geometry passed via the
xfs_da_args, and convert all the directory logging functions for
consistency.

There are many places in the directory code were we don't pass the
args into and so have to extract the geometry direct from the mount
structure. Push the args or the geometry into these leaf functions
so that we don't need to grab it from the struct xfs_mount.
This, in turn, brings use to the point where directory geometry is
no longer a property of the struct xfs_mount; it is not a global
property anymore, and hence we can start to consider per-directory
configuration of physical geometries.
Start by converting the xfs_dir_isblock/leaf code - pass in the
xfs_da_args and convert the readdir code to use xfs_da_args like
the rest of the directory code to pass information around.

They are just simple wrappers around xfs_dir2_byte_to_db(), and
we've already removed one usage earlier in the patch set. Kill

The directory code has a dependency on the struct xfs_mount to
supply the directory block geometry. Block size, block log size,
and other parameters are pre-caclulated in the struct xfs_mount or
access directly from the superblock embedded in the struct
xfs_mount.
Extract all of this geometry information out of the struct xfs_mount
and superblock and place it into a new struct xfs_da_geometry
defined by the directory code. Allocate and initialise it at mount
time, and attach it to the struct xfs_mount so it canbe passed back
into the directory code appropriately rather than using the struct
xfs_mount.

Pull x86 fixes from Peter Anvin:
"A somewhat unpleasantly large collection of small fixes. The big ones
are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It
was using __init functions with predictably suboptimal results.
Another key fix is a build fix which would produce output that simply
would not decompress correctly in some configuration, due to the
existing Makefiles picking up an unfortunate local label and mistaking
it for the global symbol _end.
Additional fixes include the handling of 64-bit numbers when setting
the vdso data page (a latent bug which became manifest when i386
started exporting a vdso with time functions), a fix to the new MSR
manipulation accessors which would cause features to not get properly
unblocked, a build fix for 32-bit userland, and a few new platform
quirks"

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:
(u64)(tk->wall_to_monotonic.tv_nsec << tk->shift)
instead of
((u64)tk->wall_to_monotonic.tv_nsec << tk->shift)
So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up
with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in
the subsequent 'while' loop.
We need an explicit cast.

Due to a typo the msr accessor function introduced in
22085a66c2fab6cf9b9393c056a3600a6b4735de didn't have any lasting
effects because they accidentally wrote the old value back.
After c0a639ad0bc6b178b46996bd1f821a04643e2bde this at the very least
this causes cpuid limits not to be lifted on some cpus leading to
missing capabilities for those.

Commit de7b2973903c "tracepoint: Use struct pointer instead of name hash
for reg/unreg tracepoints" introduces a use after free by calling
release_probes on the old struct tracepoint array before the newly
allocated array is published with rcu_assign_pointer. There is a race
window where tracepoints (RCU readers) can perform a
"use-after-grace-period-after-free", which shows up as a GPF in
stress-tests.

The replacement of the 'count' variable by two variables 'incs' and
'decs' to resolve some race conditions during module unloading was done
in parallel with some cleanup in the trace subsystem, and was integrated
as a merge.
Unfortunately, the formula for this replacement was wrong in the tracing
code, and the refcount in the traces was not usable as a result.
Use 'count = incs - decs' to compute the user count.

This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d.
commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in
tasklet(atomic context). The driver needs to use mutex to avoid
concurrency, so we can't use tasklet here, the patch need to be
removed.
The spinlock host->lock and pcr->lock may deadlock, one way to solve
the deadlock is remove host->lock in sd_isr_done_transfer(), but if
using workqueue the we can avoid using the spinlock and also avoid
the problem.
