Pull "ARM: perf: updates for 3.19" from Will Deacon:
This patch series takes us slightly further on the road to big.LITTLE
support in perf. The main change enabling this is moving the CCI PMU
driver away from the arm-pmu abstraction, allowing the arch code to
focus specifically on support for CPU PMUs.

The generic this_cpu operations disable interrupts to ensure that the
requested operation is protected from pre-emption. For arm64, this is
overkill and can hurt throughput and latency.
This patch provides arm64 specific implementations for the this_cpu
operations. Rather than disable interrupts, we use the exclusive
monitor or atomic operations as appropriate.
The following operations are implemented: add, add_return, and, or,
read, write, xchg. We also wire up a cmpxchg implementation from
cmpxchg.h.
Testing was performed using the percpu_test module and hackbench on a
Juno board running 3.18-rc4.

We currently allocate different levels of page tables with a variety of
differing flags, and the PGALLOC_GFP flags, intended for use when
allocating any level of page table, are only used for ptes in
pte_alloc_one. On x86, PGALLOC_GFP is used for all page table
allocations.
Currently the major differences are:
* __GFP_NOTRACK -- Needed to ensure page tables are always accessible in
the presence of kmemcheck to prevent recursive faults. Currently
kmemcheck cannot be selected for arm64.
* __GFP_REPEAT -- Causes the allocator to try to reclaim pages and retry
upon a failure to allocate.
* __GFP_ZERO -- Sometimes passed explicitly, sometimes zalloc variants
are used.
While we've no encountered issues so far, it would be preferable to be
consistent. This patch ensures all levels of table are allocated in the
same manner, with PGALLOC_GFP.

compatible property
This patch corrects the vendor-prefix for isl29028 in the compatible property from
"isil,isl29028" to "isl,isl29028" according to listed vendor-prefixes in
Documentation/devicetree/bindings/vendor-prefixes.txt. Incorrect vendor-prefix "isl"
was reported by checkpatch.pl warning for drivers/staging/iio/light/isl29028.c.
Thus incorrect vendor-prefix "isil" was corrected for every mention of device isl29028.

Don't disable irqs when waiting for the ST DMA "lock"; its release may
require an interrupt.
Introduce stdma_try_lock() for use in soft irq context. atari_scsi now tells
the SCSI mid-layer to defer queueing a command if the ST DMA lock is not
available, as per Michael's patch:
http://marc.info/?l=linux-m68k&m=139095335824863&w=2
The falcon_got_lock variable is race prone: we can't disable IRQs while
waiting to acquire the lock, so after acquiring it there must be some
interval during which falcon_got_lock remains false. Introduce
stdma_is_locked_by() to replace falcon_got_lock.
The falcon_got_lock tests in the EH handlers are incorrect these days. It
can happen that an EH handler is called after a command completes normally.
Remove these checks along with falcon_got_lock.
Also remove the complicated and racy fairness wait queues. If fairness is an
issue (when SCSI competes with IDE for the ST DMA interrupt), the solution
is likely to be a lower value for host->can_queue.

When trigger_all_cpu_backtrace() is called on x86, it will trigger an
NMI on each CPU and call show_regs(). But this can lead to a hard lock
up if the NMI comes in on another printk().
In order to avoid this, when the NMI triggers, it switches the printk
routine for that CPU to call a NMI safe printk function that records the
printk in a per_cpu seq_buf descriptor. After all NMIs have finished
recording its data, the seq_bufs are printed in a safe context.

"dss_fck" is a hacky clock, used to work around problems with MODULEMODE

These problems have now been solved, so we can remove the dss_fck clock.

RFBI iclk was set to point to hacky "dss_fck", which will be removed.
Instead use "l3_div_ck", which is the proper clock for this. "l3_div_ck"
is the parent of "dss_fck", so the clock rate is the same as previously.

Instead of using a hacky "dss_fck" clock (which toggles the MODULEMODE
bit) as DSS L3 interface clock, set the .modulemode field in the
omap44xx_dss_hwmod. This works now that the DSS core hwmod is enabled
during DSS submodule resets.

As the init functions necessary for machine init have moved to
generic.h, remove the unnecessary includes and prototypes definitions
from pxa-dt.c.
This removes the include of mach/pxaXXX-regs.h, and make pxa-dt generic
enough to accept other pxa variants.

In order to have a unique .c file for all pxa variants device-tree
definitions, all the initialization functions for MACHINE_START and
DT_MACHINE_START have been put together into generic.h.
The alternative would have been one pxaXXX-dt.c file per variant.
The move is necessary because each include/mach/pxaXXX.h includes the
variant register descriptions which intersects and conflicts one with
each other.
The change is a preparation for pxa-dt.c to support multiple pxa,
ie. pxa3xx and pxa27x.
The machine files including mach/pxaXXX.h all include generic.h, which
guarantees no regression should be introduced.

4bf7753b8ab7c704ca864b1653367ea9cfe68a25 introduced compilation errors
("error: 'NR_IRQS_LEGACY' undeclared (first use in this function)") because
they remove the asm/irq.h inclusion while the init_time function needs it
for the NR_IRQS_LEGACY definition.
In the other hand, the point of these commits is to remove board file
support, and init_time is only needed when booting non-DT boards, we can
thus safely remove init_time functions.
