mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues.
'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (
1fcb57d0) fixes
an issue where the ULPI PHYs were not held in reset while initializing
the EHCI controller. However, it also changes behavior in
omap-usb-host.c omap_usbhs_init by releasing reset while the
configuration in that function was done.
This change caused a regression on BB-xM where USB would not function
if 'usb start' had been run from u-boot before booting. A change was
made to release reset a little bit earlier which fixed the issue on
BB-xM and did not cause any regressions on 3430 sdp, the board for
which the fix was originally made.
This new fix, 'USB: EHCI: OMAP: Finish ehci omap phy reset cycle
before adding hcd.', (
3aa2ae74) caused a regression on OMAP5.
The original fix to hold the EHCI controller in reset during
initialization was correct, however it appears that changing
omap_usbhs_init to not hold the PHYs in reset during it's
configuration was incorrect. This patch first reverts both fixes, and
then changes ehci_hcd_omap_probe in ehci-omap.c to hold the PHYs in
reset as the original patch had done. It also is sure to incorporate
the _cansleep change that has been made in the meantime.
I've tested this on Beagleboard xM, I'd really like to get an ack from
the 3430 sdp and OMAP5 guys before getting this merged.

During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.
To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

the check was obviously incorrect.
Also fixes a couple important bugs in the eCryptfs miscdev interface.
These changes are low risk due to the small number of users that use

eCryptfs: Gracefully refuse miscdev file ops on inherited/passed files
File operations on /dev/ecryptfs would BUG() when the operations were
performed by processes other than the process that originally opened the
file. This could happen with open files inherited after fork() or file
descriptors passed through IPC mechanisms. Rather than calling BUG(), an
error code can be safely returned in most situations.
In ecryptfs_miscdev_release(), eCryptfs still needs to handle the
release even if the last file reference is being held by a process that
didn't originally open the file. ecryptfs_find_daemon_by_euid() will not
be successful, so a pointer to the daemon is stored in the file's
private_data. The private_data pointer is initialized when the miscdev
file is opened and only used when the file is released.

This reverts commit
6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252.
Conflicts:
arch/arm/kernel/ptrace.c
The new syscall restarting code can lead to problems if we take an
interrupt in userspace just before restarting the svc instruction. If
a signal is delivered when returning from the interrupt, the
TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed
from the signal handler to be treated as a restart of the previously
interrupted system call. This includes the final sigreturn call, meaning
that we may fail to exit from the signal context. Furthermore, if a
system call made from the signal handler requires a restart via the
restart_block, it is possible to clear the thread flag and fail to
restart the originally interrupted system call.
The right solution to this problem is to perform the restarting in the
kernel, avoiding the possibility of handling a further signal before the
restart is complete. Since we're almost at -rc6, let's revert the new
method for now and aim for in-kernel restarting at a later date.

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special

will prevent the rest of the chip from entering full chip idle.
To implement the idle programming cleanly, this will take some
coordination between maintainers. This is likely to take some time,
so it is probably best to leave this for 3.6 or 3.7. So, in the

ARM: Orion: Fix WDT compile for Dove and MV78xx0
Commit
0fa1f0609a0c1fe8b2be3c0089a2cb48f7fda521 (ARM: Orion: Fix
Virtual/Physical mixup with watchdog) broke the Dove & MV78xx0
build. Although these two SoC don't use the watchdog, the shared
platform code still needs to build. Add the necessary defines.

Hello,
Since ENXIO only means "offset beyond EOF" for SEEK_DATA/SEEK_HOLE,
Hence we should return the internal error unchanged if ocfs2_inode_lock() or
ocfs2_get_clusters_nocache() call failed rather than ENXIO.
Otherwise, it will confuse the user applications when they trying to understand the root cause.

eCryptfs: Properly check for O_RDONLY flag before doing privileged open
If the first attempt at opening the lower file read/write fails,
eCryptfs will retry using a privileged kthread. However, the privileged
retry should not happen if the lower file's inode is read-only because a
read/write open will still be unsuccessful.
The check for determining if the open should be retried was intended to
be based on the access mode of the lower file's open flags being
O_RDONLY, but the check was incorrectly performed. This would cause the
open to be retried by the privileged kthread, resulting in a second
failed open of the lower file. This patch corrects the check to
determine if the open request should be handled by the privileged
kthread.

floppy: cancel any pending fd_timeouts before adding a new one
In commit
070ad7e793dc ("floppy: convert to delayed work and
single-thread wq") the 'fd_timeout' timer was converted to a delayed
work. However, the "del_timer(&fd_timeout)" was lost in the process,
and any previous pending timeouts would stay active when we then
re-queued the timeout.
This resulted in the floppy probe sequence having a (stale) 20s timeout
rather than the intended 3s timeout, and thus made booting with the
floppy driver (but no actual floppy controller) take much longer than it
should.
Of course, there's little reason for most people to compile the floppy
driver into the kernel at all, which is why most people never noticed.
Canceling the delayed work where we used to do the del_timer() fixes the
issue, and makes the floppy probing use the proper new timeout instead.
The three second timeout is still very wasteful, but better than the 20s
one.

"One regression fix, two radeon fixes (one for an oops), and an i915
fix to unload framebuffers earlier.
We originally were going to leave the i915 fix until -next, but grub2
in some situations causes vesafb/efifb to be loaded now, and this
causes big slowdowns, and I have reports in rawhide I'd like to have
fixed."

cifs: when server doesn't set CAP_LARGE_READ_X, cap default rsize at MaxBufferSize
When the server doesn't advertise CAP_LARGE_READ_X, then MS-CIFS states
that you must cap the size of the read at the client's MaxBufferSize.
Unfortunately, testing with many older servers shows that they often
can't service a read larger than their own MaxBufferSize.
Since we can't assume what the server will do in this situation, we must
be conservative here for the default. When the server can't do large
reads, then assume that it can't satisfy any read larger than its
MaxBufferSize either.
Luckily almost all modern servers can do large reads, so this won't
affect them. This is really just for older win9x and OS/2 era servers.
Also, note that this patch just governs the default rsize. The admin can
always override this if he so chooses.
