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

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.

Input: request threaded-only IRQs with IRQF_ONESHOT

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.

ARM: OMAP4: hwmod data: temporarily comment out data for the usb_host_fs and aess IP blocks

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special
programming for them to enter idle.  Without this programming, they
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
meantime, prevent these IP blocks from being registered.

Later, once the appropriate support is available, this patch can be
reverted.

This second version comments out the IP block data since Benoît didn't
like removing it.

scheduling a work to unregister the trigger aren't working because there
isn't much which still runs after a panic occured (except timers).
