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.

Only set gref->gref_id if foreign access was successfully granted and
the grant ref is valid.
If gref->gref_id == -ENOSPC the test in __del_gref() would incorrectly
attempt to end foreign access (because grant_ref_t is unsigned).

We did not implement any bound on number of indirect ICBs we follow when
loading inode. Thus corrupted medium could cause kernel to go into an
infinite loop, possibly causing a stack overflow.
Fix the possible stack overflow by removing recursion from
__udf_read_inode() and limit number of indirect ICBs we follow to avoid
infinite loops.

There's no good reason to separate these since udf_fill_inode() is

If we are writing back inode of unlinked directory, its link count ends
up being (u16)-1. Although the inode is deleted, udf_iget() can load the

- Ensure that we don't mark all registers on devices using format_write()

The _SUN device indentification object is not guaranteed to return

return value, but rather execute it every time as needed. If it is
cached, an incorrect stale value may be used in some situations.

acpi_device objects for all device nodes in the namespace). Fix it

usb: fixes for v3.17-rc3
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().

goto out_unwind;

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.

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)

Up to now, when endpoint addresses in descriptors were non-consecutive,
there were created redundant files, which could cause problems in kernel,
when user tried to read/write to them. It was result of fact that maximum
endpoint address was taken as total number of endpoints in function.
This patch adds endpoint descriptors counting and storing their addresses
in eps_addrmap to verify their cohesion in each speed.
Endpoint address map would be also useful for further features, just like
vitual endpoint address mapping.

This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.

This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.
