arm: iop: specify PMUs are for XScale CPUs

2015-02-06T08:12:59+00:00

Now that we can specify which PMU variant we're likely to deal with, do
so in the iop board code. This will allow us to split the ARMv6, ARMv7,
and XScale PMU drivers.

kbuild: remove unnecessary variable initializaions

2014-10-02T11:55:02+00:00

Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.

They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

ARM: 8000/1: misc: remove deprecated IRQF_DISABLED

2014-03-12T10:32:38+00:00

This patch removes the use of the IRQF_DISABLED flag
from miscellaneous code in mach-xxx and plat-xxx

This flag is a NOOP since 2.6.35 and it will be removed one day.

ARM: iop: Switch to sched_clock_register()

2013-11-21T23:41:01+00:00

The 32 bit sched_clock interface now supports 64 bits. Upgrade to
the 64 bit function to allow us to remove the 32 bit registration
interface.

reboot: arm: change reboot_mode to use enum reboot_mode

2013-07-09T17:33:29+00:00

Preparing to move the parsing of reboot= to generic kernel code forces
the change in reboot_mode handling to use the enum.

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2013-07-06T21:09:38+00:00

Pull timer core updates from Thomas Gleixner:
 "The timer changes contain:

   - posix timer code consolidation and fixes for odd corner cases

   - sched_clock implementation moved from ARM to core code to avoid
     duplication by other architectures

   - alarm timer updates

   - clocksource and clockevents unregistration facilities

   - clocksource/events support for new hardware

   - precise nanoseconds RTC readout (Xen feature)

   - generic support for Xen suspend/resume oddities

   - the usual lot of fixes and cleanups all over the place

  The parts which touch other areas (ARM/XEN) have been coordinated with
  the relevant maintainers.  Though this results in an handful of
  trivial to solve merge conflicts, which we preferred over nasty cross
  tree merge dependencies.

  The patches which have been committed in the last few days are bug
  fixes plus the posix timer lot.  The latter was in akpms queue and
  next for quite some time; they just got forgotten and Frederic
  collected them last minute."

drivers/dma: remove unused support for MEMSET operations

2013-07-03T23:07:42+00:00

There have never been any real users of MEMSET operations since they
have been introduced in January 2007 by commit 7405f74badf4 ("dmaengine:
refactor dmaengine around dma_async_tx_descriptor").  Therefore remove
support for them for now, it can be always brought back when needed.

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13+00:00

Nothing about the sched_clock implementation in the ARM port is
specific to the architecture. Generalize the code so that other
architectures can use it by selecting GENERIC_SCHED_CLOCK.
