No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee Jones. In
particular, the debugfs and the sysct interfaces got extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
driver, with a much needed module id lookup code improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the palmas
GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
devices to switch to the new abx500 pin-ctrl driver.

Commit 81732c3b2f ("tty vt: Fix line garbage in virtual console on

commit b1a925f44a ("tty vt: Fix a regression in command line edition")
partially fixed it. However, the buffer being moved is still too large
and overflowing beyond the end of the current line, corrupting existing
characters on the next line.
Example test case:
echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B"
Expected result:

de
Current result:

Merge tag 'stable/for-linus-3.9-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen update from Konrad Rzeszutek Wilk:
"This has two new ACPI drivers for Xen - a physical CPU offline/online
and a memory hotplug. The way this works is that ACPI kicks the
drivers and they make the appropiate hypercall to the hypervisor to
tell it that there is a new CPU or memory. There also some changes to
the Xen ARM ABIs and couple of fixes. One particularly nasty bug in
the Xen PV spinlock code was fixed by Stefan Bader - and has been
there since the 2.6.32!
Features:
- Xen ACPI memory and CPU hotplug drivers - allowing Xen hypervisor
to be aware of new CPU and new DIMMs
- Cleanups
Bug-fixes:
- Fixes a long-standing bug in the PV spinlock wherein we did not
kick VCPUs that were in a tight loop.
- Fixes in the error paths for the event channel machinery"

HWPOISON: fix misjudgement of page_action() for errors on mlocked pages
memcg: stop warning on memcg_propagate_kmem

vmscan: change type of vm_total_pages to unsigned long
fs/nfsd: change type of max_delegations, nfsd_drc_max_mem and nfsd_drc_mem_used
...
The function names page_xchg_last_nid(), page_last_nid() and
reset_page_last_nid() were judged to be inconsistent so rename them to a
struct_field_op style pattern. As it looked jarring to have
reset_page_mapcount() and page_nid_reset_last() beside each other in
memmap_init_zone(), this patch also renames reset_page_mapcount() to
page_mapcount_reset(). There are others like init_page_count() but as
it is used throughout the arch code a rename would likely cause more
conflicts than it is worth.

If one storage interface or usb network interface(iSCSI case) exists in
current configuration, memory allocation with GFP_KERNEL during
usb_device_reset() might trigger I/O transfer on the storage interface
itself and cause deadlock because the 'us->dev_mutex' is held in
.pre_reset() and the storage interface can't do I/O transfer when the
reset is triggered by other interface, or the error handling can't be
completed if the reset is triggered by the storage itself (error
handling path).

Introduce the flag memalloc_noio in 'struct dev_pm_info' to help PM core
to teach mm not allocating memory with GFP_KERNEL flag for avoiding
probable deadlock.
As explained in the comment, any GFP_KERNEL allocation inside
runtime_resume() or runtime_suspend() on any one of device in the path
from one block or network device to the root device in the device tree
may cause deadlock, the introduced pm_runtime_set_memalloc_noio() sets
or clears the flag on device in the path recursively.

On linux, the pages used by kernel could not be migrated. As a result,
if a memory range is used by kernel, it cannot be hot-removed. So if we
want to hot-remove memory, we should prevent kernel from using it.
The way now used to prevent this is specify a memory range by
movablemem_map boot option and set it as ZONE_MOVABLE.
But when the system is booting, memblock will allocate memory, and
reserve the memory for kernel. And before we parse SRAT, and know the
node memory ranges, memblock is working. And it may allocate memory in
ranges to be set as ZONE_MOVABLE. This memory can be used by kernel,
and never be freed.
So, let's parse SRAT before memblock is called first. And it is early
enough.
The first call of memblock_find_in_range_node() is in:
setup_arch()
|-->setup_real_mode()
so, this patch add a function early_parse_srat() to parse SRAT, and call
it before setup_real_mode() is called.
NOTE:
1) early_parse_srat() is called before numa_init(), and has initialized
numa_meminfo. So DO NOT clear numa_nodes_parsed in numa_init() and DO
NOT zero numa_meminfo in numa_init(), otherwise we will lose memory
numa info.
2) I don't know why using count of memory affinities parsed from SRAT
as a return value in original acpi_numa_init(). So I add a static
variable srat_mem_cnt to remember this count and use it as the return
value of the new acpi_numa_init()

When (hot)adding memory into system, /sys/firmware/memmap/X/{end, start,
type} sysfs files are created. But there is no code to remove these
files. This patch implements the function to remove them.
We cannot free firmware_map_entry which is allocated by bootmem because
there is no way to do so when the system is up. But we can at least
remember the address of that memory and reuse the storage when the
memory is added next time.
This patch also introduces a new list map_entries_bootmem to link the
map entries allocated by bootmem when they are removed, and a lock to
protect it. And these entries will be reused when the memory is
hot-added again.
The idea is suggestted by Andrew Morton.
NOTE: It is unsafe to return an entry pointer and release the
map_entries_lock. So we should not hold the map_entries_lock
separately in firmware_map_find_entry() and
firmware_map_remove_entry(). Hold the map_entries_lock across find
and remove /sys/firmware/memmap/X operation.
And also, users of these two functions need to be careful to
hold the lock when using these two functions.

We remove the memory like this:
1. lock memory hotplug
2. offline a memory block
3. unlock memory hotplug
4. repeat 1-3 to offline all memory blocks
5. lock memory hotplug
6. remove memory(TODO)
7. unlock memory hotplug
All memory blocks must be offlined before removing memory. But we don't
hold the lock in the whole operation. So we should check whether all
memory blocks are offlined before step6. Otherwise, kernel maybe
panicked.
Offlining a memory block and removing a memory device can be two
different operations. Users can just offline some memory blocks without
removing the memory device. For this purpose, the kernel has held
lock_memory_hotplug() in __offline_pages(). To reuse the code for
memory hot-remove, we repeat step 1-3 to offline all the memory blocks,
repeatedly lock and unlock memory hotplug, but not hold the memory
hotplug lock in the whole operation.

Pull x86 mm changes from Peter Anvin:
"This is a huge set of several partly interrelated (and concurrently
developed) changes, which is why the branch history is messier than
one would like.
The *really* big items are two humonguous patchsets mostly developed
by Yinghai Lu at my request, which completely revamps the way we
create initial page tables. In particular, rather than estimating how
much memory we will need for page tables and then build them into that
memory -- a calculation that has shown to be incredibly fragile -- we
now build them (on 64 bits) with the aid of a "pseudo-linear mode" --
a #PF handler which creates temporary page tables on demand.
This has several advantages:
1. It makes it much easier to support things that need access to data
very early (a followon patchset uses this to load microcode way
early in the kernel startup).
2. It allows the kernel and all the kernel data objects to be invoked
from above the 4 GB limit. This allows kdump to work on very large
systems.
3. It greatly reduces the difference between Xen and native (Xen's
equivalent of the #PF handler are the temporary page tables created
by the domain builder), eliminating a bunch of fragile hooks.
The patch series also gets us a bit closer to W^X.
Additional work in this pull is the 64-bit get_user() work which you
were also involved with, and a bunch of cleanups/speedups to
__phys_addr()/__pa()."
