Currently UDF doesn't initialize i_generation in any way and thus NFS
can easily get reallocated inodes from stale file handles. Luckily UDF
already has a unique object identifier associated with each inode -
i_unique. Use that for initialization of i_generation.

NFS can easily ask for inodes that are already deleted. Currently UDF
happily returns such inodes which is a bug. Return -ESTALE if
udf_read_inode() is asked to read deleted inode.

Currently __udf_read_inode() wasn't returning anything and we found out
whether we succeeded reading inode by checking whether inode is bad or
not. udf_iget() returned NULL on failure and inode pointer otherwise.
Make these two functions properly propagate errors up the call stack and
use the return value in callers.

If a gref could not be added (perhaps because the limit has been
reached or there are no more grant references available), the undo
path may crash because __del_gref() frees the gref while it is being
used for a list iteration.
A comment suggests that using list_for_each_entry() is safe since the
gref isn't removed from the list being iterated over, but it is freed
and thus list_for_each_entry_safe() must be used.
Also, explicitly delete the gref from the local per-file list, even
though this is not strictly necessary.

A new set of fixes which have been pending for a while. All patches
have been randconfig build-tested and boot tested where applicable.
The most important fixes are MUSB on AM335x learned how to transfer
ZLPs, and net2280 got a fix for reset IRQ handling.

Fix regressions to runtime PM on OMAP and other minor fixes.
The arm64 interrupt migration code on cpu offline calls
irqchip.irq_set_affinity() with the argument force=true. Originally
this argument had no effect because it was not used by any interrupt
chip driver and there was no semantics defined.
This changed with commit 01f8fa4f01 ("genirq: Allow forcing cpu
affinity of interrupts") which made the force argument useful to route
interrupts to not yet online cpus without checking the target cpu
against the cpu online mask. The following commit ffde1de640
("irqchip: gic: Support forced affinity setting") implemented this for
the GIC interrupt controller.
As a consequence the cpu offline irq migration fails if CPU0 is
offlined, because CPU0 is still set in the affinity mask and the
validation against cpu online mask is skipped to the force argument
being true. The following first_cpu(mask) selection always selects
CPU0 as the target.
Commit 601c942176d8("arm64: use cpu_online_mask when using forced
irq_set_affinity") intended to fix the above mentioned issue but
introduced another issue where affinity can be migrated to a wrong
CPU due to unconditional copy of cpu_online_mask.
As with for arm, solve the issue by calling irq_set_affinity() with
force=false from the CPU offline irq migration code so the GIC driver
validates the affinity mask against CPU online mask and therefore
removes CPU0 from the possible target candidates. Also revert the
changes done in the commit 601c942176 as it's no longer needed.
Tested on Juno platform.

The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.
Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1". Initializing variables to
garbage values turns off GCC's uninitialized variable warnings so it
can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().

In blk-mq.c blk_mq_alloc_tag_set, if:
set->tags = kmalloc_node()
succeeds, but one of the blk_mq_init_rq_map() calls fails,
goto out_unwind;
needs to free set->tags so the caller is not obligated
to do so. None of the current callers (null_blk,
virtio_blk, virtio_blk, or the forthcoming scsi-mq)
do so.
set->tags needs to be set to NULL after doing so,
so other tag cleanup logic doesn't try to free
a stale pointer later. Also set it to NULL
in blk_mq_free_tag_set.
Tested with error injection on the forthcoming
scsi-mq + hpsa combination.

- Revert the /proc/cpuinfo changes merged during the merge window.
We've opened a can of worms here, so we need to find out where we
stand before we change this interface.
- Implement KSTK_ESP for compat tasks, otherwise 32-bit Android gets
confused wondering where its [stack] has gone

ASoC: Fixes for v3.17
A few more driver specific fixes on top of the currently pending fixes
(which are already in your tree but not Linus').
The PHY configuration is stored in an opaque "config" field, but when
allocating the structure, its proper size needs to be known. In the case
of UTMI, the proper structure is tegra_utmip_config of which a local
variable already exists, so we can use that to obtain the size from.
Fixes the following warning from the sparse checker:
drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void)
Fixes: 81d5dfe6d8 (usb: phy: tegra: Read UTMIP parameters from device tree)
