Fix a couple of problems with unlinking AFS files.
(1) The parent directory wasn't being updated properly between unlink() and
the following lookup().
It seems that, for some reason, invalidate_remote_inode() wasn't
discarding the directory contents correctly, so this patch calls
invalidate_inode_pages2() instead on non-regular files.
(2) afs_vnode_deleted_remotely() should handle vnodes that don't have a
source server recorded without oopsing.

In 9d6a8c5c213e34c475e72b245a8eb709258e968c we changed posix_test_lock
to modify its single file_lock argument instead of taking separate input
and output arguments. This makes it no longer safe to set the output
lock's fl_type to F_UNLCK before looking for a conflict, since that
means searching for a conflict against a lock with type F_UNLCK.
This fixes a regression which causes F_GETLK to incorrectly report no
conflict on most filesystems (including any filesystem that doesn't do
its own locking).
Also fix posix_lock_to_flock() to copy the lock type. This isn't
strictly necessary, since the caller already does this; but it seems
less likely to cause confusion in the future.
Thanks to Doug Chapman for the bug report.

A small regression appears to have been introduced in the recent patch
"cleanup compat ioctl handling", which was included in Linus' tree after
2.6.20.
siocdevprivate_ioctl() is no longer defined if CONFIG_NET is undefined,
whereas previously it was a dummy function in this case.
This causes compilation with CONFIG_COMPAT but without CONFIG_NET to fail.

Further fixes for AFS write support:
(1) The afs_send_pages() outer loop must do an extra iteration if it ends
with 'first == last' because 'last' is inclusive in the page set
otherwise it fails to send the last page and complete the RxRPC op under
some circumstances.
(2) Similarly, the outer loop in afs_pages_written_back() must also do an
extra iteration if it ends with 'first == last', otherwise it fails to
clear PG_writeback on the last page under some circumstances.

The check for nfs_attribute_timeout(dir) in nfs_check_verifier is
redundant: nfs_lookup_revalidate() will already call nfs_revalidate_inode()
on the parent dir when necessary.
The only case where this is not done is the case of a negative dentry. Fix
this case by moving up the revalidation code.

Since nonboot CPUs are now disabled after tasks and devices have been
frozen and the CPU hotplug infrastructure is used for this purpose, we need
special CPU hotplug notifications that will help the CPU-hotplug-aware
subsystems distinguish normal CPU hotplug events from CPU hotplug events
related to a system-wide suspend or resume operation in progress. This
patch introduces such notifications and causes them to be used during
suspend and resume transitions. It also changes all of the
CPU-hotplug-aware subsystems to take these notifications into consideration
(for now they are handled in the same way as the corresponding "normal"
ones).

It's very common for file systems to need to zero part or all of a page,
the simplist way is just to use kmap_atomic() and memset(). There's
actually a library function in include/linux/highmem.h that does exactly
that, but it's confusingly named memclear_highpage_flush(), which is
descriptive of *how* it does the work rather than what the *purpose* is.
So this patchset renames the function to zero_user_page(), and calls it
from the various places that currently open code it.
This first patch introduces the new function call, and converts all the
core kernel callsites, both the open-coded ones and the old
memclear_highpage_flush() ones. Following this patch is a series of
conversions for each file system individually, per AKPM, and finally a
patch deprecating the old call. The diffstat below shows the entire
patchset.

mapping
When a lookup request arrives, nfsd uses information provided by userspace
(mountd) to find the right filesystem.
It then assumes that the same filehandle type as the incoming filehandle can
be used to create an outgoing filehandle.
However if mountd is buggy, or maybe just being creative, the filesystem may
not support that filesystem type, and the kernel could oops, particularly if
'ex_uuid' is NULL but a FSID_UUID* filehandle type is used.
So add some proper checking that the fsid version/type from the incoming
filehandle is actually supportable, and ignore that information if it isn't
supportable.

1/ decode_sattr and decode_sattr3 never return NULL, so remove
several checks for that. ditto for xdr_decode_hyper.
2/ replace some open coded XDR_QUADLEN calls with calls to
XDR_QUADLEN
3/ in decode_writeargs, simply an 'if' to use a single
calculation.
.page_len is the length of that part of the packet that did
not fit in the first page (the head).
So the length of the data part is the remainder of the
head, plus page_len.
3/ other minor cleanups.

When the kernel calls svc_reserve to downsize the expected size of an RPC
reply, it fails to account for the possibility of a checksum at the end of
the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O
then you'll generally see messages similar to this in the server's ring
buffer:
RPC request reserved 164 but used 208
While I was never able to verify it, I suspect that this problem is also
the root cause of some oopses I've seen under these conditions:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726
This is probably also a problem for other sec= types and for NFSv4. The
large reserved size for NFSv4 compound packets seems to generally paper
over the problem, however.
This patch adds a wrapper for svc_reserve that accounts for the possibility
of a checksum. It also fixes up the appropriate callers of svc_reserve to
call the wrapper. For now, it just uses a hardcoded value that I
determined via testing. That value may need to be revised upward as things
change, or we may want to eventually add a new auth_op that attempts to
calculate this somehow.
Unfortunately, there doesn't seem to be a good way to reliably determine
the expected checksum length prior to actually calculating it, particularly
with schemes like spkm3.

The NFSv2 and NFSv3 servers do not handle WRITE requests for 0 bytes
correctly. The specifications indicate that the server should accept the
request, but it should mostly turn into a no-op. Currently, the server
will return an XDR decode error, which it should not.
Attached is a patch which addresses this issue. It also adds some boundary
checking to ensure that the request contains as much data as was requested
to be written. It also correctly handles an NFSv3 request which requests
to write more data than the server has stated that it is prepared to
handle. Previously, there was some support which looked like it should
work, but wasn't quite right.

flush_work(wq, work) doesn't need the first parameter, we can use cwq->wq

Also, rename flush_work() to cancel_work_sync() and fix all callers.

Implement support for writing to regular AFS files, including:
(1) write
(2) truncate
(3) fsync, fdatasync
(4) chmod, chown, chgrp, utime.
AFS writeback attempts to batch writes into as chunks as large as it can manage
up to the point that it writes back 65535 pages in one chunk or it meets a
locked page.
Furthermore, if a page has been written to using a particular key, then should
another write to that page use some other key, the first write will be flushed
before the second is allowed to take place. If the first write fails due to a
security error, then the page will be scrapped and reread before the second
write takes place.
If a page is dirty and the callback on it is broken by the server, then the
dirty data is not discarded (same behaviour as NFS).
Shared-writable mappings are not supported by this patch.
