David Howells 9b3f26c911 FS-Cache: Make kAFS use FS-Cache
The attached patch makes the kAFS filesystem in fs/afs/ use FS-Cache, and
through it any attached caches.  The kAFS filesystem will use caching
automatically if it's available.

Adrian Bunk c1206a2c6d fs/afs/: possible cleanups
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

Alexey Dobriyan e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig
	ia64 ia64-up
	m68k
	mips
	parisc parisc-up
	powerpc powerpc-up
	s390 s390-up
	sparc sparc-up
	sparc64 sparc64-up
	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

as well as my two usual configs.

David Howells 47051a2152 [AFS]: Fix VLocation record update wakeup
Fix the wakeup transitions after a VLocation record update completes
one way or another.  This builds on Dave Miller's partial fix.

Also move wakeups outside the spinlocked sections.

David S. Miller 39bf094930 [AFS]: Eliminate cmpxchg() usage in vlocation code.
cmpxchg() is not available on every processor so can't
be used in generic code.

Replace with spinlock protection on the ->state changes,
wakeups, and wait loops.

Add what appears to be a missing wakeup on transition
to AFS_VL_VALID state in afs_vlocation_updater().

David Howells 00d3b7a453 [AFS]: Add security support.
Add security support to the AFS filesystem.  Kerberos IV tickets are added as
RxRPC keys are added to the session keyring with the klog program.  open() and
other VFS operations then find this ticket with request_key() and either use
it immediately (eg: mkdir, unlink) or attach it to a file descriptor (open).

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
