Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().
Most conversions are straight-forward. Ones worth mentioning are,
* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
use mod_delayed_work() and cancel loop in
edac_mc_reset_delay_period() is dropped.
* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
watchdog is active or not. @fan_watchdog_active and related code
dropped.
* drivers/power/charger-manager.c: Seemingly a lot of
delayed_work_pending() abuse going on here.
[delayed_]work_pending() are unsynchronized and racy when used like
this. I converted one instance in fullbatt_handler(). Please
conver the rest so that it invokes workqueue APIs for the intended
target state rather than trying to game work item pending state
transitions. e.g. if timer should be modified - call
mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().
* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
simplified. Note that round_jiffies() calls in this function are
meaningless. round_jiffies() work on absolute jiffies not delta
delay used by delayed_work.
v2: Tomi pointed out that __cancel_delayed_work() users can't be
safely converted to mod_delayed_work(). They could be calling it
from irq context and if that happens while delayed_work_timer_fn()
is running, it could deadlock. __cancel_delayed_work() users are
dropped.

flush_scheduled_work() is going away. afs needs to make sure all the
works it has queued have finished before being unloaded and there can
be arbitrary number of pending works. Add afs_wq and use it as the
flush domain instead of the system workqueue.
Also, convert cancel_delayed_work() + flush_scheduled_work() to
cancel_delayed_work_sync() in afs_mntpt_kill_timer().

Fix a possible null pointer dereference in afs_alloc_server(): the server
pointer is NULL if there was an allocation failure, and under such a
condition, we can't dereference it in the _leave() statement.

This patch contains the following possible cleanups:
- make the following needlessly global functions static:
- rxrpc.c: afs_send_pages()
- vlocation.c: afs_vlocation_queue_for_updates()
- write.c: afs_writepages_region()
- make the following needlessly global variables static:
- mntpt.c: afs_mntpt_expiry_timeout
- proc.c: afs_vlocation_states[]
- server.c: afs_server_timeout
- vlocation.c: afs_vlocation_timeout
- vlocation.c: afs_vlocation_update_timeout
- #if 0 the following unused function:
- cell.c: afs_get_cell_maybe()
- #if 0 the following unused variables:
- callback.c: afs_vnode_update_timeout
- cmservice.c: struct afs_cm_workqueue

Make some miscellaneous changes to the AFS filesystem:
(1) Assert RCU barriers on module exit to make sure RCU has finished with
callbacks in this module.
(2) Correctly handle the AFS server returning a zero-length read.
(3) Split out data zapping calls into one function (afs_zap_data).
(4) Rename some afs_file_*() functions to afs_*() where they apply to
non-regular files too.
(5) Be consistent about the presentation of volume ID:vnode ID in debugging
output.

Add support for the create, link, symlink, unlink, mkdir, rmdir and
rename VFS operations to the in-kernel AFS filesystem.
Also:
(1) Fix dentry and inode revalidation. d_revalidate should only look at
state of the dentry. Revalidation of the contents of an inode pointed to
by a dentry is now separate.
(2) Fix afs_lookup() to hash negative dentries as well as positive ones.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
