If CONFIG_ARCH_MULTIPLATFORM & CONFIG_ARCH_MVEBU are both enabled,
__v7_pj4b_setup is added between __v7_ca9mp_setup and __v7_setup.

But there's no jump instruction added. If the chip is Cortex A5/A9,
it goes through __v7_pj4b_setup also. It results in system hang.

a47e3bc10d ARM: 7612/1: imx: Do not select some errata that depends on !ARCH_MULTIPLATFORM
Since commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access

Since imx has been converted to multiplatform, the following warning happens:

warning: (SOC_IMX6Q && ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC) selects

Recommended approach is to remove ARM_ERRATA_743622/751472 from being selected
by SOC_IMX6Q and apply such workarounds into the bootloader.

77916519cb arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces
We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and
MV78460. In fact, this is not true, and the MV78230 has only three
Ethernet interfaces.

So, the definitions of the Ethernet interfaces is now done as follows:

 * armada-370-xp.dtsi: definitions of the first two interfaces, that
   are common to Armada 370 and Armada XP

 * armada-xp.dtsi: definition of the third interface, common to all
   Armada XP variants.

 * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of
   the fourth interface.

With the change to a DT based pinctrl/gpio driver, using gpio API
calls in board-*.c files no longer works, a dereferenced NULL pointer
exception occurs instead. By converting the GPIO code into a

b24212fbfb arm: mvebu: Use dw-apb-uart instead of ns16650 as UART driver
The UART controller used in the Armada 370 and Armada XP SoCs is the
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
improper use of the ns16550 can lead to a kernel oops during boot if
a character is sent to the UART before the initialization of the
driver. The DW APB has an extra interrupt that gets raised when
writing to the LCR when busy. This explains why we need to use
dw-apb-uart driver to handle this.

This fixes up all of the smaller arches that had __dev* markings for

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

d962117687 ARM: nomadik: bump the IRQ numbers again
Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
to 32. This is the painful way to learn that if you're using
SPARSE_IRQ and avoid to define .nr_irqs in your machine,
the first 16 IRQs will be pre-allocated, and the IRQdomain
code (as the VIC core code before it) will then assume
that all IRQ descriptors are pre-allocated, and 16 of them
are - by somebody else. So mapping the IRQs will fail in
irq_create_mapping(). Moving the offset upward rids us of
this problem.

 The 3730 Beagle XM here has an intermittent failure mounting SD root,
 but the suspicion right now is that this is due to a failing SD card,
 rather than any change introduced by these patches.

logs are available here:

    http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/

The 3730 Beagle XM here has an intermittent failure mounting SD root,
but the suspicion right now is that this is due to a failing SD card,
rather than any change introduced by these patches.

This second version includes a few changes requested by Tony Lindgren.

ce73ec6db4 powerpc/vdso: Remove redundant locking in update_vsyscall_tz()
The locking in update_vsyscall_tz() is not only unnecessary because the vdso
code copies the data unproteced in __kernel_gettimeofday() but also
introduces a hard to reproduce race condition between update_vsyscall()
and update_vsyscall_tz(), which causes user space process to loop
forever in vdso code.

The following patch removes the locking from update_vsyscall_tz().

Locking is not only unnecessary because the vdso code copies the data
unprotected in __kernel_gettimeofday() but also erroneous because updating
the tb_update_count is not atomic and introduces a hard to reproduce race
condition between update_vsyscall() and update_vsyscall_tz(), which further
causes user space process to loop forever in vdso code.

The below scenario describes the race condition,
x==0	Boot CPU			other CPU
	proc_P: x==0
	    timer interrupt
		update_vsyscall
x==1		    x++;sync		settimeofday
					    update_vsyscall_tz
x==2						x++;sync
x==3		    sync;x++
						sync;x++
	proc_P: x==3 (loops until x becomes even)

Because the ++ operator would be implemented as three instructions and not
atomic on powerpc.

A similar change was made for x86 in commit 6c260d5863
("x86: vdso: Remove bogus locking in update_vsyscall_tz")

7e7fff8254 ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return values
On OMAP2xxx chips, the register bitfields for the
PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are
different than those used on OMAP3/4.  The order is reversed.  So, for
example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0
indicates 'OFF'.  Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on
OMAP3/4, 0x3 indicates 'ON'.

To fix this, we treat the OMAP3/4 values as the powerdomain API
values, and create new low-level powerdomain functions for the
OMAP2xxx chips which translate between the OMAP2xxx values and the
OMAP3/4 values.

Without this patch, the conversion of the OMAP2xxx PM code to the
functional powerstate code results in a non-booting kernel.

currently when enabling the emu_src_ck the EMU clock domain is not

1) It didn't call irq_create_mapping() once on each

2) It passed a -1 as IRQ offset for the DT case, whereas
   0 should be passed as invalid IRQ instead.

8e0d7372f5 MIPS: Alchemy: Make 32kHz and r4k timer coexist peacefully
Now that the r4k timer is registered no matter what, bump the rating of
the Alchemy 32kHz timer so that it gets used when it is working,
and fall back on the r4k when it isn't.

This fixes a timer-related hang on platform with a working 32kHz timer
(the better rated c0 timer stops while executing 'wait' leading to (almost)
eternal sleep) and an oops on boot on platforms without a working 32kHz
timer (due to double registration of the r4k timer).

dma_{alloc,free}_attrs().

Hence provide these functions, as wrappers around
dma_{alloc,free}_coherent().

Note that most architectures do it the other way around. But as so far
m68k doesn't support the attributes at all, our solution should generate

Commit 787314c35f ("Merge tag 'iommu-updates-v3.8' of

header location.

The headers were made local to mach-omap2 as they are specific to omap2+
only, and we wanted to get most of the #include <plat/*.h> headers fixed
up anyways for the ARM multiplatform support.

We attempted to avoid this kind of merge conflict early on by setting up
a minimal git branch shared by the arm-soc tree and the iommu tree, but
looks like we still hit a merge issue there as the branches got merged
as various topic branches.

787314c35f IOMMU Updates for Linux v3.8
A few new features this merge-window. The most important one is
 probably, that dma-debug now warns if a dma-handle is not checked with
 dma_mapping_error by the device driver. This requires minor changes to
 some architectures which make use of dma-debug. Most of these changes
 have the respective Acks by the Arch-Maintainers.
 Besides that there are updates to the AMD IOMMU driver for refactor the
 IOMMU-Groups support and to make sure it does not trigger a hardware
 erratum.
 The OMAP changes (for which I pulled in a branch from Tony Lindgren's
 tree) have a conflict in linux-next with the arm-soc tree. The conflict
 is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
 the arm-soc tree. It is safe to delete the file too so solve the
 conflict. Similar changes are done in the arm-soc tree in the common
 clock framework migration. A missing hunk from the patch in the IOMMU
 tree will be submitted as a seperate patch when the merge-window is
 closed.

Merge tag 'iommu-updates-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU updates from Joerg Roedel:
 "A few new features this merge-window.  The most important one is
  probably, that dma-debug now warns if a dma-handle is not checked with
  dma_mapping_error by the device driver.  This requires minor changes
  to some architectures which make use of dma-debug.  Most of these
  changes have the respective Acks by the Arch-Maintainers.

  Besides that there are updates to the AMD IOMMU driver for refactor
  the IOMMU-Groups support and to make sure it does not trigger a
  hardware erratum.

  The OMAP changes (for which I pulled in a branch from Tony Lindgren's
  tree) have a conflict in linux-next with the arm-soc tree.  The
  conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is
  deleted in the arm-soc tree.  It is safe to delete the file too so
  solve the conflict.  Similar changes are done in the arm-soc tree in
  the common clock framework migration.  A missing hunk from the patch
  in the IOMMU tree will be submitted as a seperate patch when the
  merge-window is closed."

77c8006d8d UAPI: Fix up empty files in arch/cris/
Fix up three empty files in arch/cris/ by sticking placeholder comments in
there to prevent the patch program from deleting them.

I decided not to delete the arch-v*/Kbuild files as it's possibly someone might
want to use them for genhdr-y lines in the future, but they could be deleted
and the pointer lines removed from asm/Kbuild.  The uapi/arch-v*/Kbuild files
ought to be uneffected by such a change.

asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in
uapi/asm/swab.h.  The latter, however, is exported by Kbuild.asm.

This needs to be applied after the CRIS UAPI disintegration patch.

flush_cache_louis flushes the D-side caches to the point of unification
inner-shareable. On uniprocessor CPUs, this is defined as zero and
therefore no flushing will take place. Rather than invent a new interface
for UP systems, instead use our SMP_ON_UP patching code to read the
LoUU from the CLIDR instead.

7bf9b7bef8 ARM: missing ->mmap_sem around find_vma() in swp_emulate.c
find_vma() is *not* safe when somebody else is removing vmas.  Not just
the return value might get bogus just as you are getting it (this instance
doesn't try to dereference the resulting vma), the search itself can get
buggered in rather spectacular ways.  IOW, ->mmap_sem really, really is
not optional here.

9f28ffc03e sparc64: Fix unrolled AES 256-bit key loops.
The basic scheme of the block mode assembler is that we start by
enabling the FPU, loading the key into the floating point registers,
then iterate calling the encrypt/decrypt routine for each block.

For the 256-bit key cases, we run short on registers in the unrolled
loops.

So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that
get clobbered.

The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this.

So if we have a mix of multi-block and single-block calls, the
single-block unrolled 256-bit encrypt/decrypt can run with some
of the key registers clobbered.

Handle this by always explicitly loading those registers before using
the non-unrolled 256-bit macro.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

479dda2218 ARM: EXYNOS: Fix NULL pointer dereference bug in Origen
When DRM support for Samsung SoC and Samsung S3C framebuffer support
are selected, the kernel crashes as it does not get the required
platform data. Change the compile macro to CONFIG_DRM_EXYNOS_FIMD
to fix this.

Without this patch the following crash occurs during bootup:

Unable to handle kernel NULL pointer dereference at virtual address 00000000

7f2de8171d This single patch is effectively a no-op for now. It enables architectures
to opt in to using GCC's __builtin_bswapXX() intrinsics for byteswapping,
 and if we merge this now then the architecture maintainers can enable it
 for their arch during the next cycle without dependency issues.
 
 It's worth making it a par-arch opt-in, because although in *theory* the
 compiler should never do worse than hand-coded assembler (and of course
 it also ought to do a lot better on platforms like Atom and PowerPC which
 have load-and-swap or store-and-swap instructions), that isn't always the
 case. See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46453 for example.

da844a8177 xtensa: add device trees support
Device trees allow specification of hardware topology and device
parameters at runtime instead of hard-coding them in platform setup
code. This allows running single binary kernel on a range of compatible
boards.

New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat
device tree is passed in it.

Note that current interrupt mapping scheme uses single cell for
interrupt identification. That means that IRQ numbers used in DTS must
be CPU internal IRQ numbers, not external. It is possible to extend
interrupt identification to two cells, and use second cell to tell
external IRQ numbers form internal. That would allow to use single DTS
on multiple boards with different mapping of external IRQ numbers.

00273125c3 xtensa: add s32c1i sanity check
Add a brief sanity test of S32C1I functionality.  This instruction
is needed by the kernel and userland as part of the base ABI
(including GCC atomic builtins, certain threading packages, future
atomic support in the C++ standard, etc).  However, correct operation
of this instruction requires some cooperation by hardware external to
the processor (such as bus bridge, bus fabric, or memory controller).
Minimally exercising this mechanism and reporting explicit status
early in the boot process is helpful to chip vendors using the Linux
kernel as a benchmark of correctness of hardware.

As it turns out, S32C1I is not exercised by the kernel and by uClibc
based userland as of early June 2008.  This is expected to change
soon as both incorporate more recent open source developments.

c0226e34a4 xtensa: make DoubleExceptionVector literals fit the gap
Manually load references to exc_table from the explicit literal in order
to fit DoubleExceptionVector.literals into the available 16-byte gap
before DoubleExceptionVector.text in the absence of link time
relaxation. Without this fix DoubleExceptionVector.literal section
overlaps DoubleExceptionVector.text section in the linked vmlinux image.

d95bfe464b h8300: select generic atomic64_t support
Rationales from Eric:

So I just looked a little deeper and it appears architectures that do
not support atomic64_t are broken.

The generic atomic64 support came in 2009 to support the perf subsystem
with the expectation that all architectures would implement atomic64
support.

Furthermore upon inspection of the kernel atomic64_t is used in a fair
number of places beyond the performance counters:

block/blk-cgroup.c
drivers/acpi/apei/
drivers/block/rbd.c
drivers/crypto/nx/nx.h
drivers/gpu/drm/radeon/radeon.h
drivers/infiniband/hw/ipath/
drivers/infiniband/hw/qib/
drivers/staging/octeon/
fs/xfs/
include/linux/perf_event.h
include/net/netfilter/nf_conntrack_acct.h
kernel/events/
kernel/trace/
net/mac80211/key.h
net/rds/

The block control group, infiniband, xfs, crypto, 802.11, netfilter.
Nothing quite so fundamental as fs/namespace.c but definitely in
multiplatform-code that should work, and is already broken on those
architecutres.

Looking at the implementation of atomic64_add_return in lib/atomic64.c the
code looks as efficient as these kinds of things get.

Which leads me to the conclusion that we need atomic64 support on all
architectures.

c24bf9b4cc CRIS: fix I/O macros
The inb/outb macros for CRIS are broken from a number of points of view,
missing () around parameters and they have an unprotected if statement
in them.  This was breaking the compile of IPMI on CRIS and thus I was
being annoyed by build regressions, so I fixed them.

Plus I don't think they would have worked at all, since the data values
were missing "&" and the outsl had a "3" instead of a "4" for the size.
From what I can tell, this stuff is not used at all, so this can't be
any more broken than it was before, anyway.
