abf015f046 Revert "ARM: 7098/1: kdump: copy kernel relocation code at the kexec prepare stage"
This reverts commit 2b034922af.

Will Deacon reports:

This is causing kexec to fail.

The symptoms are that the .init.text section is not loaded as part of the
new kernel image, so when we try to do the SMP/UP fixups we hit a whole sea
of poison left there by the previous kernel.

So my guess is that machine_kexec_prepare *is* too early for preparing the
reboot_code_buffer and, unless anybody has a good reason not to, I'd like to
revert the patch causing these problems.

These files didn't exist at the time of the module.h split, and
so were not fixed by the commits on that baseline.  Since they use
the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the

46bcfad7a8 cpuidle: Single/Global registration of idle states
This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.

Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu  would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.

4202735e8a cpuidle: Split cpuidle_state structure and move per-cpu statistics fields
This is the first step towards global registration of cpuidle
states. The statistics used primarily by the governor are per-cpu
and have to be split from rest of the fields inside cpuidle_state,
which would be made global i.e. single copy. The driver_data field
is also per-cpu and moved.

e978aa7d7d cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state
Cpuidle governor only suggests the state to enter using the
governor->select() interface, but allows the low level driver to
override the recommended state. The actual entered state
may be different because of software or hardware demotion. Software
demotion is done by the back-end cpuidle driver and can be accounted
correctly. Current cpuidle code uses last_state field to capture the
actual state entered and based on that updates the statistics for the
state entered.

Ideally the driver enter routine should update the counters,
and it should return the state actually entered rather than the time
spent there. The generic cpuidle code should simply handle where
the counters live in the sysfs namespace, not updating the counters.

830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

Fix:

WARNING: vmlinux.o(.text+0x1a820): Section mismatch in reference from the function eseries_register_clks() to the function .init.text:clkdev_add_table()
The function eseries_register_clks() references
the function __init clkdev_add_table().
This is often because eseries_register_clks lacks a __init
annotation or the annotation of clkdev_add_table is wrong.

by adding the __init annotation to eseries_register_clks() - this
function is only called from other __init-marked functions.  While
we're here, mark it static as it's only called from within eseries.c.

fc01387302 ARM: OMAP: change get_context_loss_count ret value to int
get_context_loss_count functions return context loss count as u32, and
zero means an error. However, zero is also returned when context has
never been lost and could also be returned when the context loss count
has wrapped and goes to zero.

Change the functions to return an int, with negative value meaning an
error.

OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the
hsmmc code handles the returned value as an int, with negative value
meaning an error, this patch actually fixes hsmmc code also.

ace9021698 ARM: OMAP3: hwmod: fix variant registration and remove SmartReflex from common list
Commit d6504acd21 ("OMAP2+: hwmod:
remove OMAP_CHIP*") tests the inverse condition of what it should be
testing for the return value from omap_hwmod_register().  This causes
several IP blocks to not be registered on several OMAP3 family devices.

Fixing that bug also unmasked another bug, originally reported by
Chase Maupin <chase.maupin@ti.com> and then subsequently by Abhilash K
V <abhilash.kv@ti.com>, which caused SmartReflex IP blocks to be
registered on SoCs that don't support them.

Commit 4d17aeb1c5 ("OMAP: I2C: split
device registration and convert OMAP2+ to omap_device") makes
omap2_i2c_add_bus() return a pointer to an omap_device instead on
success instead of 0.

This breaks the omap_register_i2c_bus() ABI and results in the igep0020
board code detecting an I2C bus registration error when there is none.

Fix the problem by using PTR_RET() instead of PTR_ERR() in
omap2_i2c_add_bus().

eb7c792da5 arch/tile: factor out <arch/opcode.h> header
The kernel code was using some <asm> headers that included a mix
of hardware-specific information (typically found in Tilera <arch>
headers) and structures, enums, and function declarations supporting
the disassembly function of the tile-desc.c sources.

This change refactors that code so that a hardware-specific, but
OS- and application-agnostic header, is created: <arch/opcode.h>.
This header is then exported to userspace along with the other
<arch> headers and can be used to build userspace code; in particular,
it is used by glibc as part of implementing the backtrace() function.

The new header, together with a header that specifically describes
the disassembly code (<asm/tile-desc.h> with _32 and _64 variants),
replaces the old <asm/opcode-tile*.h> and <asm/opcode_constants*.h>
headers.

As part of this change, we are also renaming the 32-bit constants
from TILE_xxx to TILEPRO_xxx to better reflect the fact that they
are specific to the TILEPro architecture, and not to TILE-Gx
and any successor "tile" architecture chips.

f319d6e238 arch/tile: avoid exporting a symbol no longer used by gcc
An earlier Tilera compiler generated calls to an "__ll_mul"
function for long long multiplication.  Our libgcc supported that
as an alias for the normal __muldi3 routine, so we made it available
to kernel modules as well.  However, for a while now the compiler
has internally been generating only the standard __muldi3 symbol,
and the version we are giving back to the community does not have
the __ll_mul alias, so we are removing it from the kernel too.

e0b1f39d55 arch/tile: avoid ISO namespace pollution with <asm/sigcontext.h>
<asm/sigcontext.h> is used by glibc's <bits/sigcontext.h> from <signal.h>,
which means that it can't clutter the namespace with random symbols
or #defines.  However, we use <arch/abi.h> to get a suitable type to
hold a machine register.

This change makes <arch/abi.h> safe to use in this kind of context
if __need_int_reg_t is defined prior to including the file; in that
case, it only defines a few symbols that are safe in the ISO namespace
(prefixed with double underscores).  <asm/sigcontext.h> then uses
the __uint_reg_t type instead of the normal uint_reg_t.

6ca6ca5d81 powerpc/83xx: Add shutdown request support to MCU handling on MPC8349 MITX
This patch add support for calling ctrl_alt_del() when the power button is
pressed for more than about 2 seconds on some freescale MPC83xx evaluation
boards and reference design.

The code uses a kthread to poll the CTRL_BTN bit each second.

Also change Kconfig entry of the driver to bool, as device's gpio
registration is broken when loading as module.

Tested on an MPC8315E RDB board.

e80dd9a7bc arch/powerpc/sysdev/fsl_rio.c: release rapidio port I/O region resource if port failed to initialize
The "struct rio_mport" contains a member of master port I/O memory
resource structure "struct resource iores".  This resource will be read
from device tree and be used for rapidio R/W transaction memory space.
Rapidio requests the port I/O memory resource under the root resource
"iomem_resource".

			struct rio_mport *port;
			port = kzalloc(sizeof(struct rio_mport), GFP_KERNEL);

			request_resource(&iomem_resource, &port->iores);

When port failed to initialize, allocated "rio_mport" structure memory
will be freed, and the port I/O memory resource structure pointer
"&port->iores" will be invalid.  If other requests resource under
"iomem_resource", "&port->iores" node may be operated in the child
resources list and this will cause the system to crash.

So the requested port I/O memory resource should be released before
freeing allocated "rio_mport" structure.

405e44f2e3 powerpc: get_hugepte() don't put_page() the wrong page
"page" may have changed to point to the next hugepage after the loop
completed, The references have been taken on the head page, so the
put_page must happen there too.

This is a longstanding issue pre-thp inclusion.

It's totally unclear how these page_cache_add_speculative and
pte_val(pte) != pte_val(*ptep) checks are necessary across all the
powerpc gup_fast code, when x86 doesn't need any of that: there's no way
the page can be freed with irq disabled so we're guaranteed the
atomic_inc will happen on a page with page_count > 0 (so not needing the
speculative check).

The pte check is also meaningless on x86: no need to rollback on x86 if
the pte changed, because the pte can still change a CPU tick after the
check succeeded and it won't be rolled back in that case.  The important
thing is we got a reference on a valid page that was mapped there a CPU
tick ago.  So not knowing the soft tlb refill code of ppc64 in great
detail I'm not removing the "speculative" page_count increase and the
pte checks across all the code, but unless there's a strong reason for
it they should be later cleaned up too.

If a pte can change from huge to non-huge (like it could happen with
THP) passing a pte_t *ptep to gup_hugepte() would also require to repeat

2839bdc1bf powerpc: remove superfluous PageTail checks on the pte gup_fast
This part of gup_fast doesn't seem capable of handling hugetlbfs ptes,
those should be handled by gup_hugepd only, so these checks are
superfluous.

Plus if this wasn't a noop, it would have oopsed because, the insistence
of using the speculative refcounting would trigger a VM_BUG_ON if a tail
page was encountered in the page_cache_get_speculative().

70b50f94f1 mm: thp: tail page refcounting fix
Michel while working on the working set estimation code, noticed that
calling get_page_unless_zero() on a random pfn_to_page(random_pfn)
wasn't safe, if the pfn ended up being a tail page of a transparent
hugepage under splitting by __split_huge_page_refcount().

He then found the problem could also theoretically materialize with
page_cache_get_speculative() during the speculative radix tree lookups
that uses get_page_unless_zero() in SMP if the radix tree page is freed
and reallocated and get_user_pages is called on it before
page_cache_get_speculative has a chance to call get_page_unless_zero().

So the best way to fix the problem is to keep page_tail->_count zero at
all times.  This will guarantee that get_page_unless_zero() can never
succeed on any tail page.  page_tail->_mapcount is guaranteed zero and
is unused for all tail pages of a compound page, so we can simply
account the tail page references there and transfer them to
tail_page->_count in __split_huge_page_refcount() (in addition to the
head_page->_mapcount).

While debugging this s/_count/_mapcount/ change I also noticed get_page is
called by direct-io.c on pages returned by get_user_pages.  That wasn't
entirely safe because the two atomic_inc in get_page weren't atomic.  As
opposed to other get_user_page users like secondary-MMU page fault to
establish the shadow pagetables would never call any superflous get_page
after get_user_page returns.  It's safer to make get_page universally safe
for tail pages and to use get_page_foll() within follow_page (inside
get_user_pages()).  get_page_foll() is safe to do the refcounting for tail
pages without taking any locks because it is run within PT lock protected
critical sections (PT lock for pte and page_table_lock for
pmd_trans_huge).

The standard get_page() as invoked by direct-io instead will now take
the compound_lock but still only for tail pages.  The direct-io paths
are usually I/O bound and the compound_lock is per THP so very
finegrined, so there's no risk of scalability issues with it.  A simple
direct-io benchmarks with all lockdep prove locking and spinlock
debugging infrastructure enabled shows identical performance and no
overhead.  So it's worth it.  Ideally direct-io should stop calling
get_page() on pages returned by get_user_pages().  The spinlock in
get_page() is already optimized away for no-THP builds but doing
get_page() on tail pages returned by GUP is generally a rare operation
and usually only run in I/O paths.

This new refcounting on page_tail->_mapcount in addition to avoiding new
RCU critical sections will also allow the working set estimation code to
work without any further complexity associated to the tail page
refcounting with THP.

8535639810 um: fix ubd cow size
ubd_file_size() cannot use ubd_dev->cow.file because at this time
ubd_dev->cow.file is not initialized.
Therefore, ubd_file_size() will always report a wrong disk size when
COW files are used.
Reading from /dev/ubd* would crash the kernel.

We have to read the correct disk size from the COW file's backing
file.

For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM),
so there's no need to pass sa_mask elements in arguments.  For another, the
flags depend only on whether it's an IRQ signal or not (we add SA_RESTART
for them).

47a6770ac6 msm: boards: Fix fallout from removal of machine_desc in fixup
After 0744a3ee (ARM: platform fixups: remove mdesc argument to
fixup function, 2010-12-20) the fixup functions introduced in
9e775ad (ARM: 7012/1: Set proper TEXT_OFFSET for newer MSMs,
2011-08-12) cause warnings like:

arch/arm/mach-msm/board-msm8x60.c:85: warning: initialization
from incompatible pointer type

Fix them by removing the machine_desc argument from the fixup
functions.
