A reasonably common NAS server returns an error on the SetFSInfo of
the Unix capabilities. Log a message for this alerting the user
that the server may have problems with the Unix extensions,
and telling them what they can do to workaround it.

Unfortunately the server does not return other clues
that we could easily use to turn the Unix Extension support
off automatically in this case (since they claim to support it).

There is a small memory leak in fs/cifs/inode.c::cifs_mkdir().
Storage for 'pInfo' is allocated with kzalloc(), but if the call
to CIFSPOSIXCreate(...) happens to return 0 and pInfo->Type == -1,
then we'll jump to the 'mkdir_get_info' label without freeing the
storage allocated for 'pInfo'.
This patch adds a kfree() call to free the storage just before
jumping to the label, thus getting rid of the leak.

cifs reconnect could end up happening incorrectly due to
the small initial tcp recvmsg response. When the socket
was within three bytes of being full and the recvmsg
returned only 1 to 3 bytes of the initial 4 byte
read of the RFC1001 length field. Fortunately this
seems to be less common on more current kernels, but
this fixes it so cifs tries to retrieve all 4 bytes
of the initial tcp read.

On a mount without posix extensions enabled, when an unlock request is
made, the client can release more than is intended. To reproduce, on a
CIFS mount without posix extensions enabled:

1) open file
2) do fcntl lock: start=0 len=1
3) do fcntl lock: start=2 len=1
4) do fcntl unlock: start=0 len=1

...on the unlock call the client sends an unlock request to the server
for both locks. The problem is a bad test in cifs_lock.

This reverts commit 196705c9.  It was
reported to cause a regression by Daniel Exner, and Arjan van de Ven
points out that we actually already have infrastructure in place for
setting limits on acceptable DMA latency that would be the much more
correct fix for the problem with some Broadcom EHCI controllers.

Fixed up trivial conflicts due to the changes to support big-endian host
controller descriptors in drivers/usb/host/{ehci-sched.c,ehci.h}.

This patch uses kzalloc to zero all of struct dio rather than manually
trying to track which fields we rely on being zero.  It passed aio+dio
stress testing and some bug regression testing on ext3.

This patch was introduced by Linus in the conversation that lead up to
Badari's minimal fix to manually zero .map_bh.b_state in commit:

  6a648fa7

It makes the code a bit smaller.  Maybe a couple fewer cachelines to
load, if we're lucky:

   text    data     bss     dec     hex filename
3285925  568506 1304616 5159047  4eb887 vmlinux
3285797  568506 1304616 5158919  4eb807 vmlinux.patched

I was unable to measure a stable difference in the number of cpu cycles
spent in blockdev_direct_IO() when pushing aio+dio 256K reads at
~340MB/s.

So the resulting intent of the patch isn't a performance gain but to
avoid exposing ourselves to the risk of finding another field like
.map_bh.b_state where we rely on zeroing but don't enforce it in the
code.

This ensures that a bootconsole is unregistered if it is not replaced.
The current implementation spews garbage out the bootconsole in this case,
since the bootconsole structure is normally in the init section, and is

Programming DMA mode may destroy current PIO mode setting so if
CONFIG_HPT34X_AUTODMA=n (the default case) make ide_tune_dma() fail
early by disabling all host DMA masks and re-tune PIO mode.

for some other changes.
