Helge Deller 92b5992982 parisc: optimize mtsp(0,sr) inline assembly
If the value which should be moved into a space register is zero, we can
optimize the inline assembly to become "mtsp %r0,%srX".

Helge Deller 594174d810 parisc: switch to gzip-compressed vmlinuz kernel
The latest PA-RISC Boot Loader (palo) allows loading of gzip compressed
vmlinuz kernels. So let's now switch to build a vmlinuz file when we
build a palo boot image.

PALO version 1.9 (or higher) is required for this which is available at
git://git.kernel.org/pub/scm/linux/kernel/git/deller/palo.git

Linus Torvalds 21884a83b2 Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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."

This is the long awaited simplification of irqdomain. It gets rid of the

 can be supported in a single domain. Doing this removes a lot of special
 case code and makes irq domains simpler to understand overall.

Mark Brown d7cabeed83 dmaengine: PL08x: Avoid collisions with get_signal() macro
As pointed out by Arnd Bergmann there is a get_signal macro definied in
linux/signal.h which can conflict with the platform data callback
function of the same name leading to confusing errors from the compiler
(especially if signal.h manages to get pulled into the driver itself due
to header dependencies).  Avoid such errors by renaming get_signal and
put_signal in the platform data to get_xfer_signal and put_xfer_signal.

 - Remove #ifdef from linux/of_platform.h to increase compiler syntax
   coverage
 - Bug fix for address decoding on Bimini and js2x powerpc platforms.
 - miscellaneous binding changes
 
 One note on the above. The binding changes going in from all kinds of
 different trees has gotten rather out of hand. I picked up some during
 this cycle, but even going though my tree isn't a great fit. Ian
 Campbell has prototyped splitting the bindings and .dtb files into a
 separate repository. The plan is to migrate to using that sometime in
 the next few kernel releases which should get rid of a lot of the churn
 on binding docs and .dts files.

Linus Torvalds 98f486f18d Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
 - new drivers: Kontron PLD, Wondermedia VT
 - mv64xxx driver gained sun4i support and a bigger cleanup
 - duplicate driver 'intel-mid' removed
 - added generic device tree binding for sda holding time (and
   designware driver already uses it)
 - we tried to allow driver probing with only device tree and no i2c
   ids, but I had to revert it because of side effects.  Needs some
   rethinking.
 - driver bugfixes, cleanups...

Linus Torvalds e61aca5158 Merge branch 'kconfig-diet' from Dave Hansen
Merge Kconfig menu diet patches from Dave Hansen:
 "I think the "Kernel Hacking" menu has gotten a bit out of hand.  It is
  over 120 lines long on my system with everything enabled and options
  are scattered around it haphazardly.

        http://sr71.net/~dave/linux/kconfig-horror.png

  Let's try to introduce some sanity.  This set takes that 120 lines
  down to 55 and makes it vastly easier to find some things.  It's a
  start.

  This set stands on its own, but there is plenty of room for follow-up
  patches.  The arch-specific debug options still end up getting stuck
  in the top-level "kernel hacking" menu.  OPTIMIZE_INLINING, for
  instance, could obviously go in to the "compiler options" menu, but
  the fact that it is defined in arch/ in a separate Kconfig file keeps
  it on its own for the moment.

  The Signed-off-by's in here look funky.  I changed employers while
  working on this set, so I have signoffs from both email addresses"

* emailed patches from Dave Hansen <dave@sr71.net>:
  hang and lockup detection menu
  kconfig: consolidate printk options
  group locking debugging options
  consolidate compilation option configs
  consolidate runtime testing configs
  order memory debugging Kconfig options
  consolidate per-arch stack overflow debugging options
2013-07-04 11:25:51 -07:00
Dave Hansen d1a1dc0be8 consolidate per-arch stack overflow debugging options
Original posting:

	http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com

Several architectures have similar stack debugging config options.
They all pretty much do the same thing, some with slightly
differing help text.

This patch changes the architectures to instead enable a Kconfig
boolean, and then use that boolean in the generic Kconfig.debug
to present the actual menu option.  This removes a bunch of
duplication and adds consistency across arches.

Linus Torvalds 65b97fb730 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
 "This is the powerpc changes for the 3.11 merge window.  In addition to
  the usual bug fixes and small updates, the main highlights are:

   - Support for transparent huge pages by Aneesh Kumar for 64-bit
     server processors.  This allows the use of 16M pages as transparent
     huge pages on kernels compiled with a 64K base page size.

   - Base VFIO support for KVM on power by Alexey Kardashevskiy

   - Wiring up of our nvram to the pstore infrastructure, including
     putting compressed oopses in there by Aruna Balakrishnaiah

   - Move, rework and improve our "EEH" (basically PCI error handling
     and recovery) infrastructure.  It is no longer specific to pseries
     but is now usable by the new "powernv" platform as well (no
     hypervisor) by Gavin Shan.

   - I fixed some bugs in our math-emu instruction decoding and made it
     usable to emulate some optional FP instructions on processors with
     hard FP that lack them (such as fsqrt on Freescale embedded
     processors).

   - Support for Power8 "Event Based Branch" facility by Michael
     Ellerman.  This facility allows what is basically "userspace
     interrupts" for performance monitor events.

   - A bunch of Transactional Memory vs.  Signals bug fixes and HW
     breakpoint/watchpoint fixes by Michael Neuling.

  And more ...  I appologize in advance if I've failed to highlight
  something that somebody deemed worth it."

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (156 commits)

Alexandre Bounine fdf90abc00 rapidio: add modular build option for the subsystem core
Add a configuration option to build RapidIO subsystem core code as a
loadable kernel module.  Currently this option is available only for
x86-based platforms, with the additional patch for PowerPC planned to be
provided later.

This patch replaces kernel command line parameter "riohdid=" with its
module-specific analog "rapidio.hdid=".

Zhang Yanfei 8bdc237ac1 s390: remove setting for saved_max_pfn
The only user of saved_max_pfn in s390 is read_oldmem interface but we
have removed that interface, so saved_max_pfn is now unneeded in s390, and
we needn't set it anymore.

Zhang Yanfei 427fcd23b5 powerpc: Remove savemaxmem parameter setup
saved_max_pfn is used to know the amount of memory that the previous
kernel used.  And for powerpc, we set saved_max_pfn by passing the kernel
commandline parameter "savemaxmem=".

The only user of saved_max_pfn in powerpc is read_oldmem interface.  Since
we have removed read_oldmem, we don't need this parameter anymore.

Xianglong Du e88b815e01 drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVI
On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider
(RTC_DIV) that divides the input 32.768KHz clock to the frequency that
users need (E.g.  1 Hz).  The divided real-time clock will be used to
drive a 32-bit counter (RTC_COUNTER) that provides users with the actual
time.

In each cycle of the divided real-time clock, there is a Hertz interrupt
generated to the RISC.  Users can also configure an alarm (RTC_ALARM).
When RTC_COUNTER matches the alarm, there will be an alarm interrupt
generated to the RISC.

The system RTC can generate an alarm wake-up signal to notify the power
controller to wake up from power saving mode.

There have never been any real users of MEMSET operations since they
have been introduced in January 2007 by commit 7405f74bad ("dmaengine:
refactor dmaengine around dma_async_tx_descriptor").  Therefore remove
support for them for now, it can be always brought back when needed.

'cmdline' is a NUL terminated string, when its length < 4, memcmp()
will cause memory access out of boundary.

So use strncmp() instead of memcmp().
