Tobias Klauser 595e8fabea microblaze: Storage class should be before const qualifier
The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

Benjamin Herrenschmidt 0203d6ec4e powerpc: Fix setting of oprofile cpu type
commit 2657dd4e30 introduced a
bug where we would now always override the "real" oprofile CPU
type with the "compatible" one provided by a pseudo-PVR in the
device-tree which is incorrect and breaks oprofile on all current
configs since the "compatible" ones aren't yet recognized.

This fixes it.

Michael Wolf 79af6c49a9 powerpc adjust oprofile_cpu_type version 3
Oprofile is changing the naming it is using for the compatibility modes.
Instead of having compat-power<x>, oprofile will go to family naming
convention and use ibm-compat-v<x>.  Currently only ibm-compat-v1 will
be defined.
The notion of compatibility events just started with POWER6. So there is
no way that any other tool could exist that is using these
oprofile_cpu_type strings we want to change.

John Wright 2f65dd475c x86: gettimeofday() vDSO: fix segfault when tv == NULL
According to the gettimeofday(2) manual:

       If either tv or tz is NULL, the corresponding structure is not
       set or returned.

Since it is legal to give NULL as the tv argument, the code should make
sure tv is not NULL before trying to dereference it.

This issue manifests itself on x86_64 when vdso=0 is not on the kernel
command-line and libc uses the vDSO for gettimeofday() (e.g. glibc >=
2.7).  A simple reproducer:

  #include <stdio.h>
  #include <sys/time.h>

  int main(void)
  {
      struct timezone tz;

      gettimeofday(NULL, &tz);

      return 0;
  }

See http://bugs.debian.org/466491 for more details.

Tim Abbott 13beadd91f powerpc: Revert switch to TEXT_TEXT in linker script
Commit edada399 broke the build on 64-bit powerpc because it moved the
__ftr_alt_* sections of a file away from the .text section, causing
link failures due to relative conditional branch targets being too far
away from the branch instructions.  This happens on pretty much all
64-bit powerpc configs.

This change reverts commit edada399 while preserving the update from
the *.refok sections to .ref.text that has happened since.

Michael Ellerman ff61e5ccc3 powerpc/cell: Select PCI for IBM_CELL_BLADE AND CELLEB
Currently PPC_CELL_NATIVE selects PPC_OF_PLATFORM_PCI, but does not
select PCI. This can lead to a config with the former and the latter
disabled, which does not build.

To fix this PPC_CELL_NATIVE should select PCI. However, that would
force PCI on for QPACE, which also selects PPC_CELL_NATIVE. So
instead move the select of PPC_OF_PLATFORM_PCI and PCI under both
IBM_CELL_BLADE and CELLEB.

Kumar Gala 2e8aead1b5 powerpc: ppc32 needs elf_read_implies_exec()
On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries
because old toolchains had bugs where they didn't mark program
segments executable that needed to be.  For some reason we didn't do
this on ppc32 builds.  This hadn't been an issue until commit 8d30c14c
("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side
effect that we are now enforcing execute permissions to some extent on
32-bit 4xx and Book E processors.

This fixes it by defining elf_read_implies_exec on 32-bit to turn on
the read-implies-exec behaviour on programs that are sufficiently old
that they don't have a PT_GNU_STACK program header.

David Brownell 3e9c18e1dc davinci: DM644x: NAND: update partitioning
Update NAND partitioning for the dm6446 evm, unmasking the hidden
data at the beginning and letting the kernel be updated from Linux.

 - This is boot-compatible with TI's software (U-Boot 1.20 and both
   the 2.6.10 and 2.6.18 kernels), in terms of startup and loading
   kernels from flash.

 - In the same way, it's also boot-compatible with mainline U-Boot,
   which stores U-Boot params in block 0 not block 16.

 - It's not quite compatible with systems that previously used NAND
   partitions to hold (filesystem) data.  The compatibilities are a
   bit different based on which kernel was used previously
     + Users of TI/MV kernels no longer see mtd2 "params"
       (mainline u-boot env is in a different place)
	* Filesystem is now mtd2 ... vs mtd3
     + Users of GIT kernels now see mtd0 and mtd1 partitions
	* Filesystem partition starts 640 KBytes earlier
	* Filesystem is now mtd2 ... vs mtd0
     * Linux now *uses* the flash-resident BBT
	* Removes annoying slowdown/hiccup during boot
	* Potentially ~64KB less space available with TI/MV kernels

If you *used* NAND partitions from Linux, there is no solution that's
fully compatible with all previous kernels in those respects ... ergo
this "best compromise".  It'd be good to back back up the filesystem
data; or, carry your own backwards-compatibility patch for awhile.

David Brownell 474dad54ba davinci: gpio bugfixes
Update the DaVinci GPIO code to work better on non-dm6446 parts,
notably the dm355:

 - Only handle the number of GPIOs the chip actually has.  So
   for example on dm6467, GPIO-42 is the last GPIO, and trying
   to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446.

 - Enable GPIO interrupts on each 16-bit GPIO-irq bank ...
   previously, only the first five were enabled, so GPIO-80
   and above (on dm355) wouldn't trigger IRQs.

 - Use the right IRQ for each GPIO bank.  The wrong values were
   used for dm355 chips, so GPIO IRQs got routed incorrectly.

 - Handle up to four pairs of 16-bit GPIO banks ... previously
   only three were handled, so accessing GPIO-96 and up (e.g. on
   dm355) would oops.

 - Update several comments that were dm6446-specific.

Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs
on the DM355 EVM.

One thing this doesn't do is handle the way some of the GPIO
numbers on dm6467 are reserved but aren't valid as GPIOs.  Some
bitmap logic could fix that if needed.

David Howells 9a523d427d FRV: Stop gcc from generating uninitialised variable warnings after BUG()
Stop gcc from generating uninitialised variable warnings after BUG().
The problem is that FRV's call into its gdbstub appears to return (if
the function is marked noreturn, then the compiler is under no
obligation to pass it a return address, and so GDB won't know where the
bug happened).

To get around this, we make the do...while wrapper in _debug_bug_trap()
an endless loop from which there's no escape.

Paul Mundt ecd4ca52bf sh: Fix up unsigned syscall_nr in SH-5 pt_regs.
syscall_nr is presently defined as unsigned in the SH-5 pt_regs,
while the syscall restarting code wants it to be signed. Fix this
up, and bring it in line with the other SH parts.

Eric Miao 15fbc93857 [ARM] pxa/zylonite: fix the issue of unused SDATA_IN_1 pin get AC97 not working
GPIO17_SDATA_IN_1 and GPIO36_SDATA_IN_1 are originally designed for the 2nd
codec but unused on the board, yet they are initialized incorrectly by the
bootloader as the SDATA_IN_1 alternate function, thus causing AC97 fail to
work. Fix this issue by configuring these pins as normal GPIO to avoid the
noise from these pins being treated as signals from the 2nd codec.

Valentine Barshak 644e28f342 powerpc/44x: Correct memory size calculation for denali-based boards
Some U-Boot versions incorrectly set the number of chipselects to two
for Sequoia/Rainier boards while they only have one chipselect hardwired.
This patch adds a workaround for this, hardcoding the number of chipselects
to one for sequioa/rainer board models and reading the actual value from
the memory controller register DDR0_10 otherwise.

It also fixes another error in the way ibm4xx_denali_fixup_memsize
calculates memory size. When testing the DDR_REDUC bit, the polarity is
backwards.  A "1" implies 32-bit wide memory while a "0" implies 64-bit
wide memory.

While it is fine for hackers to continue to use "hpet=force"

Paul Walmsley f248076c0d OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c files
Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12.  Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management.  GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management.  GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it
may not be available for Linux use.

It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below.  Modify board-omap3beagle.c to use GPTIMER12.

This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.

Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of
this patch - thanks Kalle.

Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and
3430SDP.

Commit 8ad8ff6548 breaks the OMAP2xxx
cpu_mask code, which causes OMAP2xxx to panic on boot.  Fix by
removing the cpu_mask auto variable and by changing CK_242X
and CK_243X to use RATE_IN_242X/RATE_IN_243X.

Nicolas Pitre fdd8b079e3 [ARM] 5460/1: Orion: reduce namespace pollution
Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

Kevin Hilman b3bb4f688c ARM: OMAP2/3: GPIO: do not attempt to wake-enable
The GPIO IRQ enable/disable path attempts to also enable IRQ wake
support for the parent GPIO bank IRQ as well.  However, since there is
no 'set_wake' hook for the bank IRQs, these calls will always fail.
Also, since the enable will fail on the suspend path, the disable on
the resume path will trigger unbalanced enable/disable warnings.

This was discovered in the suspend/resume path on OMAP3/Beagle using
the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the
suspend/resume path.

vi arch/arm/mach-omap2/usb-tusb6010.c +111	- tusb_set_sync_mode()

is -ENODEV appropriate when sysclk_ps == 0?

This was found by code analysis, please review.
------------------------------>8-------------8<---------------------------------
gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is
not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it
seems. In tusb_set_sync_mode() this may result in a division by zero.
