Fix a gcc warning (and bug?) introduced in cc9a6c877 ("cpuset: mm: reduce
large amounts of memory barrier related damage v3")
Local variable "page" can be uninitialized if the nodemask from vma policy
does not intersects with nodemask from cpuset. Even if it doesn't happens
it is better to initialize this variable explicitly than to introduce
a kernel oops in a weird corner case.

The comments above __alloc_bootmem_node() claim that the code will
first try the allocation using 'goal' and if that fails it will
try again but with the 'goal' requirement dropped.
Unfortunately, this is not what the code does, so fix it to do so.
This is important for nobootmem conversions to architectures such
as sparc where MAX_DMA_ADDRESS is infinity.
On such architectures all of the allocations done by generic spots,
such as the sparse-vmemmap implementation, will pass in:
__pa(MAX_DMA_ADDRESS)
as the goal, and with the limit given as "-1" this will always fail
unless we add the appropriate fallback logic here.

Commit 026cee0086 had the side-effect of dropping the '=' from
the unknown boot arguments that are passed to init as environment
variables. This is because parse_args() puts a NUL in the string
where the '=' was when it passes the "param" and "val" pointers
to the parsing subfunctions. Previously, unknown_bootoption() was
the last parse_args() subfunction to run, and it carefully put back
the '=' character. Now the ignore_unknown_bootoption() is the last
one to run, and it wasn't doing the necessary repair, so the
envp params ended up with the embedded NUL and were no longer
seen as valid environment variables by init.

This patch instructs DLM to prevent an "in place" conversion, where the
lock just stays on the granted queue, and instead forces the conversion to
the back of the convert queue. This is done on upward conversions only.
This is useful in cases where, for example, a lock is frequently needed in
PR on one node, but another node needs it temporarily in EX to update it.
This may happen, for example, when the rindex is being updated by gfs2_grow.
The gfs2_grow needs to have the lock in EX, but the other nodes need to
re-read it to retrieve the updates. The glock is already granted in PR on
the non-growing nodes, so this prevents them from continually re-granting
the lock in PR, and forces the EX from gfs2_grow to go through.

dlm: fix QUECVT when convert queue is empty
Mel reports a BUG_ON(slot == NULL) in radix_tree_tag_set() on s390
3.0.13: called from __set_page_dirty_nobuffers() when page_remove_rmap()
tries to transfer dirty flag from s390 storage key to struct page and
radix_tree.
That would be because of reclaim's shrink_page_list() calling
add_to_swap() on this page at the same time: first PageSwapCache is set
(causing page_mapping(page) to appear as &swapper_space), then
page->private set, then tree_lock taken, then page inserted into
radix_tree - so there's an interval before taking the lock when the
radix_tree slot is empty.
We could fix this by moving __add_to_swap_cache()'s spin_lock_irq up
before the SetPageSwapCache. But a better fix is simply to do what's
five years overdue: Ken Chen introduced __set_page_dirty_no_writeback()
(if !PageDirty TestSetPageDirty) for tmpfs to skip all the radix_tree
overhead, and swap is just the same - it ignores the radix_tree tag, and
does not participate in dirty page accounting, so should be using
__set_page_dirty_no_writeback() too.
s390 testing now confirms that this does indeed fix the problem.

commit c744a65c1e
md: don't set md arrays to readonly on shutdown.
removed the possibility of a 'BUG' when data is written to an array
that has just been switched to read-only, but also introduced the
possibility that the array metadata could be corrupted.
If, when md_notify_reboot gets the mddev lock, the array is
in a state where it is assembled but hasn't been started (as can
happen if the personality module is not available, or in other unusual
situations), then incorrect metadata will be written out making it
impossible to re-assemble the array.
So only call __md_stop_writes() if the array has actually been
activated.
This patch is needed for any stable kernel which has had the above
commit applied.

Instead of only when the array is degraded, it is now called whenever
md_check_recovery finds anything useful to do, which includes
updating the metadata for clean<->dirty transition.
This causes unnecessary work, and causes info messages from ->add_disk
to be reported much too often.
So refine md_check_recovery to only do any actual recovery checking

For the particular issue of x32, which shares code with i386 in the
handling of compat_siginfo_t, the use of a 64-bit clock_t bumps the
sigchld structure out of alignment, which triggers a messy cascade of
padding.
This was already handled on the kernel compat side, but it needs
handling on the user space side, which uses the generic header. To
make that possible:
1. Allow __kernel_clock_t to be overridden in struct siginfo;
2. Allow there to be attributes added to struct siginfo.

With commit a2ef5c4fd4
"ACPI: Move module parameter gts and bfs to sleep.c" the
wake_sleep_flags is required when calling acpi_enter_sleep_state.
The assembler code in wakeup_*.S did not do that. One solution
is to call it from assembler and stick the wake_sleep_flags on
the stack (for 32-bit) or in %esi (for 64-bit). hpa and rafael
both suggested however to create a wrapper function to call
acpi_enter_sleep_state and call said wrapper function
("acpi_enter_s3") from assembler.
For 32-bit, the acpi_enter_s3 ends up looking as so:
push %ebp
mov %esp,%ebp
sub $0x8,%esp
movzbl 0xc1809314,%eax [wake_sleep_flags]
movl $0x3,(%esp)
mov %eax,0x4(%esp)
call 0xc12d1fa0 <acpi_enter_sleep_state>
leave
ret
And 64-bit:
movzbl 0x9afde1(%rip),%esi [wake_sleep_flags]
push %rbp
mov $0x3,%edi
mov %rsp,%rbp
callq 0xffffffff812e9800 <acpi_enter_sleep_state>

A small fallout from Vinod's conversions to dma_transfer_direction,
this small comparison was done with a dma_data_direction instead.
Fix it by comparing against the correct enum.

The patch "ARM: amba: Remove AMBA level regulator support" breaks
the DMA40 driver since the <linux/amba/bus.h> header implicitly
included the regulator consumer header. So include it explicitly
and fix the build error.

can be directly stopped by issuing a SUSPEND_REQ on the EE
bits. There is no need to suspend the physical channel and
restart it.
Also, the support for pre-V2 hw is discontinued.
EE bits for writing:
00: disable only if AS=11 or AS=00
01: enable
10: suspend_req only if AS=01 & EE=01 or EE=11
11: round / no change for writing

Remove custom hack and make use of the notifier chain interfaces for
delivering events from the ports to their associated clients.
Clients that want to receive port events need to register their callbacks
using hsi_register_port_event(). The callbacks can be called in interrupt
context. Use hsi_unregestier_port_event() to undo the registration.

Pull ARM fixes from Russell King:
"Here's my usual Sunday push, just for one revert which PeterZ hollered
about after last weeks push. Other than that, all seems strangely
quiet as far as fixes go in non-platform ARM land at the moment."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
Revert "ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus"
Pull powerpc fixes from Benjamin Herrenschmidt:
"Here are a few fixes for powerpc. Note the addition to the generic
irq.h. This is part of a 3-patches regression fix for mpic due to
changes in how IRQ_TYPE_NONE is being handled. Thomas agreed to the
addition of the new IRQ_TYPE_DEFAULT contant, however he hasn't
replied with an Ack to the actual patch yet. I don't to wait much
longer with these patches tho."
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc/mpic: Properly set default triggers
irq: Add IRQ_TYPE_DEFAULT for use by PIC drivers
powerpc/mpic: Fix confusion between hw_irq and virq
powerpc/pmac: Don't add_timer() twice

This gets rid of the unused default senses array, and replaces the
incorrect use of IRQ_TYPE_NONE with the new IRQ_TYPE_DEFAULT for
the initial set_trigger() call when mapping an interrupt.
This in turn makes us read the HW state and update the irq desc
accordingly.
