Pull drm fixes from Dave Airlie:
"I realise this a bit bigger than I would want at this point.
Exynos is a large chunk, I got them to half what they wanted already,
and hey its ARM based, so not going to hurt many people.
Radeon has only two fixes, but the PLL fixes were a bit bigger, but
required for a lot of scenarios, the fence fix is really urgent.
vmwgfx: I've pulled in a dumb ioctl support patch that I was going to
shove in later and cc stable, but we need it asap, its mainly to stop
mesa growing a really ugly dependency in userspace to run stuff on
vmware, and if I don't stick it in the kernel now, everyone will have
to ship ugly userspace libs to workaround it.
nouveau: single urgent fix found in F18 testing, causes X to not start
properly when f18 plymouth is used
i915: smattering of fixes and debug quieting
gma500: single regression fix
So as I said a bit large, but its fairly well scattered and its all
stuff I'll be shipping in F18's 3.6 kernel."

vfs: make O_PATH file descriptors usable for 'fstat()'
We already use them for openat() and friends, but fstat() also wants to
be able to use O_PATH file descriptors. This should make it more
directly comparable to the O_SEARCH of Solaris.
Note that you could already do the same thing with "fstatat()" and an
empty path, but just doing "fstat()" directly is simpler and faster, so
there is no reason not to just allow it directly.
See also commit
332a2e1244bd, which did the same thing for fchdir, for

eCryptfs: Copy up attributes of the lower target inode after rename
After calling into the lower filesystem to do a rename, the lower target
inode's attributes were not copied up to the eCryptfs target inode. This
resulted in the eCryptfs target inode staying around, rather than being
evicted, because i_nlink was not updated for the eCryptfs inode. This
also meant that eCryptfs didn't do the final iput() on the lower target
inode so it stayed around, as well. This would result in a failure to
free up space occupied by the target file in the rename() operation.
Both target inodes would eventually be evicted when the eCryptfs
filesystem was unmounted.
This patch calls fsstack_copy_attr_all() after the lower filesystem
does its ->rename() so that important inode attributes, such as i_nlink,
are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called
and eCryptfs can drop its final reference on the lower inode.

eCryptfs: Call lower ->flush() from ecryptfs_flush()
Since eCryptfs only calls fput() on the lower file in

If the lower filesystem implements ->flush(), then eCryptfs should try
to flush out any dirty pages prior to calling the lower ->flush(). If
the lower filesystem does not implement ->flush(), then eCryptfs has no
need to do anything in ecryptfs_flush() since dirty pages are now

821f749 eCryptfs: Revert to a writethrough cache model
That patch reverted some code (specifically,
32001d6f) that was
necessary to properly handle open() -> mmap() -> close() -> dirty pages
-> munmap(), because the lower file could be closed before the dirty
pages are written out.
Rather than reapplying
32001d6f, this approach is a better way of
ensuring that the lower file is still open in order to handle writing
out the dirty pages. It is called from ecryptfs_release(), while we have
a lock on the lower file pointer, just before the lower file gets the
final fput() and we overwrite the pointer.

bnx2x: Add missing afex code
Commit
a334872224a67b614dc888460377862621f3dac7 added afex support but lacked
several logical changes. This lack can cause afex to crash, and also
have a slight effect on other flows (i.e., driver always assumes the Tx ring

scsi_netlink: Remove dead and buggy code
The scsi netlink code confuses the netlink port id with a process id,
going so far as to read NETLINK_CREDS(skb)->pid instead of the correct
NETLINK_CB(skb).pid. Fortunately it does not matter because nothing
registers to respond to scsi netlink requests.
The only interesting use of the scsi_netlink interface is
fc_host_post_vendor_event which sends a netlink multicast message.
Since nothing registers to handle scsi netlink messages kill all of the
registration logic, while retaining the same error handling behavior
preserving the userspace visible behavior and removing all of the
confused code that thought a netlink port id was a process id.
This was tested with a kernel allyesconfig build which had no problems.

net: qmi_wwan: call subdriver with control intf only
This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.
commit
230718bd net: qmi_wwan: bind to both control and data interface
changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function. The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.
The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended. Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.
