42c604ba7c ARM: OMAP2+: fix wrong address when loading PRM_FRAC_INCREMENTOR_DENUMERATOR_RELOAD
The denominator should be load from INCREMENTOR_DENUMERATOR_RELOAD_OFFSET
rather than INCREMENTER_NUMERATOR_OFFSET.

This is more likely a typo, since INCREMENTER_DENUMERATOR_RELOAD[23:17] is
reserved. It seems that it won't make much trouble without this fix, because
the useful [11:0] bits are mask and set the right value. Anyway, reading
from a right address is better choice.

From Tony Lindgren:
Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>:

This series removes the currently-unused PRCM macros from
arch/arm/mach-omap2.

Basic test logs are available at:

http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/

Once, years ago, we thought that it would be good to document the PRCM
register bits in the Linux codebase.  Most folks in the broader
community did not have access to the same documentation, so we thought
that they might be able to use these bits to fix bugs and improve the
code.

We were also able to autogenerate most of these macros, so it was
thought that defining them in advance would reduce the risk of error,
inconsistencies, and merge conflicts caused when patch sets
incrementally defined them by hand.

Well, nice thoughts.  But the first rationale was rendered partially
obsolete when TI started to release public TRM documentation PDFs at
some point in the OMAP3 timeframe.  (Despite their weaknesses, TI's
public OMAP TRMs remain the most useful public documentation available
for any ARM Linux SoC -- at least to the extent of my knowledge.)  And
then the current Linux development tropism towards
development-by-negative-diffstat obliterated the remainder of the
above two philosophies.

So, for the few, the masochistic, out there who wish to continue
developing TI PRCM code, I would ask that you resurrect any
additionally-needed macros from these commits, rather than writing
them manually.  Purely for the sake of a pleasant atavism, perhaps; the
way one appreciates a used bookstore, or a video rental store...

And thanks to the upstream maintainers for being patient while we
adjust.

7dedd34694 ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL
With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.

This was rootcaused to hwmod trying to reset console uart while
earlycon was using it.  The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.

Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.

This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

8bd26e3a7e arm: delete __cpuinit/__CPUINIT usage from all ARM users
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit  -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings.  In any case, they are temporary and harmless.

This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code.  It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.

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."
