0a428036df arm: tegra: dts: Mark USB1 as an OTG port on Seaboard
The USB1 port on Tegra2 supports operation in host or device modes. On
Seaboard this is possible, so mark the port as OTG.

ba202f15cd arm: tegra: dts: Add legacy mode support to Tegra2x USB1 port
Tegra's USB1 port supports legacy mode, so mark it as such. Even if we
don't use it, we must turn it off in the driver.

2b43e4e586 ARM: OMAP2+: Fix build error after merge
Commit 9890ce44 (ARM: get rid of asm/irq.h in asm/prom.h)
removed include of asm/irq.h in asm/prom.h. This commit
together with recent omap cleanup to remove io.h causes
build breakage:

arrch/arm/mach-omap2/control.c: In function 'omap3_ctrl_write_boot_mode':
arch/arm/mach-omap2/control.c:238: error:
'OMAP343X_CTRL_BASE' undeclared (first use in this function)
...

Fix this by including hardware.h directly where needed
instead of relying on asm/irq.h in asm/prom.h.

4cd7c0a03e C6X: fix KSTK_EIP and KSTK_ESP macros
There was a latent typo in the C6X KSTK_EIP and KSTK_ESP macros which
caused a problem with a new patch which used them. The broken definitions
were of the form:

  #define KSTK_FOO(tsk) (task_pt_regs(task)->foo)

Note the use of task vs tsk. This actually worked before because the
only place in the kernel which used these macros passed in a local
pointer named task.

Fix this by using ACCESS_ONCE() instead of rcu_dereference_check_mce()
over mcelog.next. Since the access to each entry is controlled by the
->finished field, ACCESS_ONCE() should work just fine. An rcu_dereference
is unnecessary here.

5727347180 ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling mode
On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.

Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.

This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

ad5b7f1350 powerpc: Make SPARSE_IRQ required
All IRQs on powerpc are managed via irq_domain anyway, there isn't really
any advantage to turning SPARSE_IRQ off, and it's the direction we want
to take the kernel design anyway.  This patch makes powerpc always use
SPARSE_IRQ.

On pseries_defconfig, SPARSE_IRQ adds only about 0x300 bytes to the
.text sections, and removes about 0x20000 from the data section for the
static irq_desc table.

and significantly less memory is thus shown to the partition. As far as
I can tell, the constant used is arbitrary. Ben Herrenschmidt provided
additional background that

and that it is likely not very useful any longer.

a2007ce844 powerpc: Use set_current_blocked() and block_sigmask()
As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this
code wrong, so using this helper function should stop that from
happening again.

de801de139 powerpc/icswx: Fix race condition with IPI setting ACOP
There is a race where a thread causes a coprocessor type to be valid
in its own ACOP _and_ in the current context, but it does not
propagate to the ACOP register of other threads in time for them to
use it.  The original code tries to solve this by sending an IPI to
all threads on the system, which is heavy handed, but unfortunately
still provides a window where the icswx is issued by other threads and
the ACOP is not up to date.

This patch detects that the ACOP DSI fault was a "false positive" and
syncs the ACOP and causes the icswx to be replayed.
