6550162200 xtensa: add config option to disable linker relaxation
The default linker behavior is to optimize identical literal values and
remove unnecessary overhead from assembler-generated "longcall" sequences
to reduce code size. Provide an option to disable this behavior to improve
compile time.

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.

c36e0501ee x86, paravirt: fix build error when thp is disabled
With CONFIG_PARAVIRT=y and CONFIG_TRANSPARENT_HUGEPAGE=n, the build breaks
because set_pmd_at() is undeclared:

  mm/memory.c: In function 'do_pmd_numa_page':
  mm/memory.c:3520: error: implicit declaration of function 'set_pmd_at'
  mm/mprotect.c: In function 'change_pmd_protnuma':
  mm/mprotect.c:120: error: implicit declaration of function 'set_pmd_at'

This is because paravirt defines set_pmd_at() only when
CONFIG_TRANSPARENT_HUGEPAGE=y and such a restriction is unneeded.  The
fix is to define it for all CONFIG_PARAVIRT configurations.

06d0b5d9ed xen/smp: Use smp_store_boot_cpu_info() to store cpu info for BSP during boot time.
Git commit 30106c1743
("x86, hotplug: Support functions for CPU0 online/offline") alters what
the call to smp_store_cpu_info() does. For BSP we should use the
smp_store_boot_cpu_info() and for secondary CPU's the old
variant of smp_store_cpu_info() should be used. This fixes
the regression introduced by said commit.

0ad50c3896 compat: generic compat_sys_sched_rr_get_interval() implementation
This function is used by sparc, powerpc tile and arm64 for compat support.
 The patch adds a generic implementation with a wrapper for PowerPC to do
the u32->int sign extension.

The reason for a single patch covering powerpc, tile, sparc and arm64 is
to keep it bisectable, otherwise kernel building may fail with mismatched
function declarations.

Currently the __define_initcall() macro takes three arguments, fn, id and

wrapped in quotes.  To overcome this need to specify three arguments to
the __define_initcall macro, where one argument is the stringification of
another, we can just use the stringification macro instead.

6a2b60b17b Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
 "While small this set of changes is very significant with respect to
  containers in general and user namespaces in particular.  The user
  space interface is now complete.

  This set of changes adds support for unprivileged users to create user
  namespaces and as a user namespace root to create other namespaces.
  The tyranny of supporting suid root preventing unprivileged users from
  using cool new kernel features is broken.

  This set of changes completes the work on setns, adding support for
  the pid, user, mount namespaces.

  This set of changes includes a bunch of basic pid namespace
  cleanups/simplifications.  Of particular significance is the rework of
  the pid namespace cleanup so it no longer requires sending out
  tendrils into all kinds of unexpected cleanup paths for operation.  At
  least one case of broken error handling is fixed by this cleanup.

  The files under /proc/<pid>/ns/ have been converted from regular files
  to magic symlinks which prevents incorrect caching by the VFS,
  ensuring the files always refer to the namespace the process is
  currently using and ensuring that the ptrace_mayaccess permission
  checks are always applied.

  The files under /proc/<pid>/ns/ have been given stable inode numbers
  so it is now possible to see if different processes share the same
  namespaces.

  Through the David Miller's net tree are changes to relax many of the
  permission checks in the networking stack to allowing the user
  namespace root to usefully use the networking stack.  Similar changes
  for the mount namespace and the pid namespace are coming through my
  tree.

  Two small changes to add user namespace support were commited here adn
  in David Miller's -net tree so that I could complete the work on the
  /proc/<pid>/ns/ files in this tree.

  Work remains to make it safe to build user namespaces and 9p, afs,
  ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the
  Kconfig guard remains in place preventing that user namespaces from
  being built when any of those filesystems are enabled.

  Future design work remains to allow root users outside of the initial
  user namespace to mount more than just /proc and /sys."

Commit 2ac29a1 (ARM: PMU: fix runtime PM enable) moved the call to
pm_runtime_enable() from the OMAP2+ PMU code into the ARM PERF core
code. However, header for pm_runtime which should have been removed
from the OMAP2+ PMU code was not. It is no longer necessary to include
this header in the OMAP2+ PMU code and so remove it.

0698811fad ARM: OMAP2+: enable devtmpfs and devtmpfs automount
Since udev-182, udev no longer creates device nodes under /dev
and this has to be managed by the kernel devtmpfs filesystem.

This means that a kernel built with the current OMAP2+ config
will not boot on a system with a recent udev.

Also, it is good to have /dev automatically mounted since some
non-initramfs based setups assumes this and don't manually mount it.

There is several different SoCs sharing the sun5i codename: A10s, A12

Moreover, some boards like the olinuxino come in A10s and A13 variants,
which also share the same SoC codename.

So change the naming scheme to reflect both the codename and the market

69155fd66d ARM i.MX51 clock: Fix regression since enabling MIPI/HSP clocks
The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree.
It turned out that the system does not work properly when the MIPI/HSP
clocks are enabled, but the IPU clock is disabled. This happens when
IPU support is disabled. In this case the IPU clock gets disabled when
the clock framework turns off unused clock in a late_initcall. This
is broken since:

| Date:   Tue Jun 5 13:53:32 2012 +0200
|
|     ARM i.MX5: switch IPU clk support to devicetree bindings
|
|     The i.MX5 clk support has platform based clock bindings for the
|     IPU. IPU support is devicetree only, so move them over to devicetree
|     based bindings. Also, enable MIPI clocks which do not have a device
|     associated with, but still need to be enabled to do graphics on
|     i.MX51.

This patch fixes this by setting some reserved bits in the CCM as recommended
in the reference manual.

Merge tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma

Pull Automatic NUMA Balancing bare-bones from Mel Gorman:
 "There are three implementations for NUMA balancing, this tree
  (balancenuma), numacore which has been developed in tip/master and
  autonuma which is in aa.git.

  In almost all respects balancenuma is the dumbest of the three because
  its main impact is on the VM side with no attempt to be smart about
  scheduling.  In the interest of getting the ball rolling, it would be
  desirable to see this much merged for 3.8 with the view to building
  scheduler smarts on top and adapting the VM where required for 3.9.

  The most recent set of comparisons available from different people are

    mel:    https://lkml.org/lkml/2012/12/9/108
    mingo:  https://lkml.org/lkml/2012/12/7/331
    tglx:   https://lkml.org/lkml/2012/12/10/437
    srikar: https://lkml.org/lkml/2012/12/10/397

  The results are a mixed bag.  In my own tests, balancenuma does
  reasonably well.  It's dumb as rocks and does not regress against
  mainline.  On the other hand, Ingo's tests shows that balancenuma is
  incapable of converging for this workloads driven by perf which is bad
  but is potentially explained by the lack of scheduler smarts.  Thomas'
  results show balancenuma improves on mainline but falls far short of
  numacore or autonuma.  Srikar's results indicate we all suffer on a
  large machine with imbalanced node sizes.

  My own testing showed that recent numacore results have improved
  dramatically, particularly in the last week but not universally.
  We've butted heads heavily on system CPU usage and high levels of
  migration even when it shows that overall performance is better.
  There are also cases where it regresses.  Of interest is that for
  specjbb in some configurations it will regress for lower numbers of
  warehouses and show gains for higher numbers which is not reported by
  the tool by default and sometimes missed in treports.  Recently I
  reported for numacore that the JVM was crashing with
  NullPointerExceptions but currently it's unclear what the source of
  this problem is.  Initially I thought it was in how numacore batch
  handles PTEs but I'm no longer think this is the case.  It's possible
  numacore is just able to trigger it due to higher rates of migration.

  These reports were quite late in the cycle so I/we would like to start
  with this tree as it contains much of the code we can agree on and has
  not changed significantly over the last 2-3 weeks."

dad5451a32 ARM: 7605/1: vmlinux.lds: Move .notes section next to the rodata
The .notes, being read-only data by nature, were placed between
read-write .data and .bss. This was harmful in case of the XIP
kernel, as being placed in the RAM range, most likely far
from the ROM address, was inflating the XIP images.

Moving the .notes at the end of the read-only section
(consisting of .text, .rodata and unwind info) fixes the problem.

It causes odd bootup problems on x86-64.  Markus Trippelsdorf gets a

this commit reverted.

So we don't know exactly what is wrong with the commit, but it's
definitely problematic, and worth reverting sooner rather than later.

29f0667f92 ARM: OMAP4: Fix EMU clock domain always on
Commit d043d87 (ARM: OMAP2+: clockdomain: bypass clockdomain handling
when disabling unused clks) skips the decrementing of a clock-domains
use count if the clocks use count is zero. However, for OMAP4 devices
this is causing the EMU clock-domain to be stuck ON as the use count is
not getting decremented correctly.

The scenario that leads to this problem is described below ...

omap_hwmod_setup_all
--> _setup
    --> clkdm_hwmod_enable
    	--> EMU clock domain usecount = 1
    --> _enable_clocks
        --> clk_enable
	    --> trace_clk_div_div usecount = 1
            --> clkdm_hwmod_enable
    	        --> EMU clock domain usecount = 2
--> _idle
    --> _disable_clocks
	--> clk_disable
            --> trace_clk_div_div usecount = 0
            --> clkdm_hwmod_disable
                --> skips decrement of EMU clock domain usecount
		    because trace_clk_div_div is 0!
    	        --> EMU clock domain usecount = 2
    --> clkdm_hwmod_disable
    	--> EMU clock domain usecount = 1

Hence, due to the order that a clocks use count is decremented and the
clock domain is disabled, it is possible that the clock domain can have
a non-zero use count when the actual clock has a use count of 0.
Therefore, we should only bypass the clock-domain handling when both the
clock-domain and clock in the clock-domain have a use count of 0 and
warn when the clock-domain has a zero use count and the clock has a
non-zero use count.

8c197ccfb6 ARM: OMAP4460: Workaround ABE DPLL failing to turn-on
With the latest mainline u-boot bootloader (v2012.10), timers (5-8) in
the ABE power domain are failing to turn-on. The timers never come out
of the disabled state when setting the module-mode field to enable.

The problem was exposed when u-boot was updated to NOT configure and
lock the ABE DPLL on start-up. If the ABE DPLL is configured and locked
by u-boot the problem does not occur. However, if the ABE DPLL is in the
idle low-power bypass state and we attempt to enable a timer in the ABE
power domain, it remains stuck in the disabled state. It appears to be a
problem the timer interface clock as this comes from the ABE DPLL.

If we place the ABE DPLL in the MN-bypass state and not the idle
low-power state, then this problem is not seen.

This problem only appears to occur on OMAP4460 and not OMAP4430.

Workaround this problem by locking the ABE DPLL for OMAP4460 in the
kernel on boot. By locking the ABE DPLL, when clocks from the ABE DPLL
are not being requested the DPLL will transition into a low-power stop
mode.

3ff51ed828 ARM: OMAP4: Enhance support for DPLLs with 4X multiplier
On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can
be enabled or disabled in addition to the standard configurable
multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X
multiplier is accounted for by checking to see whether it is enabled or
not. However, when calculating a new rate we only check to see if the
rate can be achieved with the current setting for the 4X multiplier.
Enhance the round_rate() function for such DPLLs to see if the rate
can be achieved with the 4X multiplier if it cannot be achieved without
the 4X multiplier.

This change is necessary, because when using the 32kHz clock as the
source clock for the ABE DPLL, the default DPLL frequency for the ABE
DPLL cannot be achieved without enabling the 4X multiplier.

When using the 32kHz clock as the source clock for the ABE DPLL and
attempting to lock the DPLL to 98.304MHz (default frequency), it was
found that the DPLL would fail to lock if the low-power mode for the DPLL
was not enabled. From reviewing boot-loader settings that configure the
ABE DPLL it was found that the low-power mode is enabled when using the
32kHz clock source, however, the documentation for OMAP does not state
that this is a requirement. Therefore, introduce a new function for
OMAP4 devices to see if low-power mode can be enabled when calculating a
new rate to ensure the DPLL will lock.

New variables for the last calculated 4X multiplier and low-power
setting have been added to the dpll data structure as well as variables
defining the bit mask for enabling these features via the DPLL's
control_reg. It is possible that we could eliminate these bit masks from
the dpll data structure as these bit masks are not unique to OMAP4, if
it is preferred.

The function omap3_noncore_program_dpll() has been updated to avoid
passing the calculated values for the multiplier (M) and divider (N) as
these are stored in the clk structure.

9b4fcc8694 ARM: OMAP4: Add function table for non-M4X dplls
Currently all OMAP4 non-core DPLLs use the same function table for
configuring DPLLs. For these DPLLs, the function
omap4_dpll_regm4xen_recalc() is used to recalculate the DPLL rate and
the function omap4_dpll_regm4xen_round_rate() is used to calculate the
closest rate to that requested. However, these omap4_dpll_regm4xen_xxx()
functions are only applicable to the ABE DPLL and not the other non-core
DPLLs. Therefore, add a new function table for non-core DPLLs that do
not include the 4X-multiplier (M4X).

Please note that using these omap4_dpll_regm4x_xxx() function works for
the non-M4X DPLLs today because we only check to see if the 4X
multiplier is enabled when calculating the rate. However, it is planned
that the dpll functions will be enhanced to enable the 4X multiplier as
necessary (in order to achieve the requested rate) and so calling these
functions for non-M4X dplls will no longer work.

c2714334b9 ARM: arm-soc: Updates for Marvell mvebu/kirkwood
This is a branch with updates for Marvell's mvebu/kirkwood platforms. They
 came in late-ish, and were heavily interdependent such that it didn't
 make sense to split them up across the cross-platform topic branches. So
 here they are (for the second release in a row) in a branch on their own.

Ethernet is not currently working on the OMAP2420 H4 board. In commit
f604931 (ARM: OMAP: abstract debug card setup (smc, leds)) the function
h4_init_smc91x() that initialised the ethernet controller was renamed to
h4_init_debug() but was never called when initialising the board.

Adding a call to h4_init_debug() fixes ethernet support, however,
instead of using the legacy H4 code migrate the H4 to use the
gpmc_smc91x_init() function instead and remove the legacy H4 code.

ca2e16faa7 OMAP: board-files: fix i2c_bus for tfp410
The i2c handling in tfp410 driver, which handles converting parallel RGB
to DVI, was changed in 958f2717b8
(OMAPDSS: TFP410: pdata rewrite). The patch changed what value the
driver considers as invalid/undefined.  Before the patch, 0 was the
invalid value, but as 0 is a valid bus number, the patch changed this to
-1.

However, the fact was missed that many board files do not define the bus
number at all, thus it's left to 0. This causes the driver to fail to
get the i2c bus, exiting from the driver's probe with an error, meaning
that the DVI output does not work for those boards.

This patch fixes the issue by changing the i2c_bus number field in the
driver's platform data from u16 to int, and setting the bus number to -1
in the board files for the boards that did not define the bus. The
exception is devkit8000, for which the bus is set to 1, which is the
correct bus for that board.

The bug exists in v3.5+ kernels.

  they are fed first in the initramfs blob (lots of bootloaders can

e0c3e27ce1 ARM: AM335x: Fix warning in timer.c
When compiling the kernel with configuration options ...

 # CONFIG_ARCH_OMAP2 is not set
 # CONFIG_ARCH_OMAP3 is not set
 # CONFIG_ARCH_OMAP4 is not set
 # CONFIG_SOC_OMAP5 is not set
 CONFIG_SOC_AM33XX=y

 ... the following build warning is seen.

  CC      arch/arm/mach-omap2/timer.o
  arch/arm/mach-omap2/timer.c:395:19: warning: ‘omap2_sync32k_clocksource_init’
  	defined but not used [-Wunused-function]

This issue was introduced by commit 6f80b3b (ARM: OMAP2+: timer: remove
CONFIG_OMAP_32K_TIMER) where the omap2_sync32k_clocksource_init() is no
longer referenced by the timer initialisation function for the AM335x
device as it has no 32k-sync timer.

Fix this by adding the "__maybe_unused" compiler directive to the
omap2_sync32k_clocksource_init() function to indicate that this function
may be used for certain configurations.

34cceb7464 ARM: OMAP2+: Fix realtime_counter_init warning in timer.c
In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time
counter), the function realtime_counter_init() was added. However, if
the kernel configuration option CONFIG_SOC_OMAP5 is not selected then
the following compiler warning is observed.

  CC      arch/arm/mach-omap2/timer.o
  arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’
  defined but not used [-Wunused-function]

Commit fa6d79d also introduced the kernel configuration option
CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the
a stub function for realtime_counter_init() is defined.

For non-OMAP5 devices, there is no realtime counter and so
realtime_counter_init() function and stub function are not used for
these devices. Therefore, fix this warning by only allowing the kernel
configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for
OMAP5 devices.

82fab442f5 modules: don't hand 0 to vmalloc.
In commit d0a21265df David Rientjes unified various archs'
module_alloc implementation (including x86) and removed the graduitous
shortcut for size == 0.

Then, in commit de7d2b567d, Joe Perches added a warning for
zero-length vmallocs, which can happen without kallsyms on modules
with no init sections (eg. zlib_deflate).

Fix this once and for all; the module code has to handle zero length
anyway, so get it right at the caller and remove the now-gratuitous
checks within the arch-specific module_alloc implementations.

34e1169d99 module: add syscall to load module from fd
As part of the effort to create a stronger boundary between root and
kernel, Chrome OS wants to be able to enforce that kernel modules are
being loaded only from our read-only crypto-hash verified (dm_verity)
root filesystem. Since the init_module syscall hands the kernel a module
as a memory blob, no reasoning about the origin of the blob can be made.

Earlier proposals for appending signatures to kernel modules would not be
useful in Chrome OS, since it would involve adding an additional set of
keys to our kernel and builds for no good reason: we already trust the
contents of our root filesystem. We don't need to verify those kernel
modules a second time. Having to do signature checking on module loading
would slow us down and be redundant. All we need to know is where a
module is coming from so we can say yes/no to loading it.

If a file descriptor is used as the source of a kernel module, many more
things can be reasoned about. In Chrome OS's case, we could enforce that
the module lives on the filesystem we expect it to live on.  In the case
of IMA (or other LSMs), it would be possible, for example, to examine
extended attributes that may contain signatures over the contents of
the module.

This introduces a new syscall (on x86), similar to init_module, that has
only two arguments. The first argument is used as a file descriptor to
the module and the second argument is a pointer to the NULL terminated
string of module arguments.

 that i.MX was converted in one of the earlier cleanup branches as

db5b0ae007 ARM: arm-soc: device tree conversions and enablement
Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
 smaller series as well.
 
 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.

a16dad7763 MIPS: Fix potencial corruption
Normally r4k_dma_cache_inv should only ever be called with cacheline
aligned addresses.  If however, it isn't there is the theoretical
possibility of data corruption.  There is no correct way of handling this
and anyway, it should only happen if the DMA API is used incorrectly
so drop

There is a different corruption scenario with these CACHE instructions
removed but again there is no way of handling this correctly and it can
be triggered only through incorrect use of the DMA API.

So just get rid of the complexity.
