Introduce a new API vmemmap_free() to free and remove vmemmap
pagetables. Since pagetable implements are different, each architecture
has to provide its own version of vmemmap_free(), just like
vmemmap_populate().
Note: vmemmap_free() is not implemented for ia64, ppc, s390, and sparc.

When memory is removed, the corresponding pagetables should alse be
removed. This patch introduces some common APIs to support vmemmap
pagetable and x86_64 architecture direct mapping pagetable removing.
All pages of virtual mapping in removed memory cannot be freed if some
pages used as PGD/PUD include not only removed memory but also other
memory. So this patch uses the following way to check whether a page
can be freed or not.
1) When removing memory, the page structs of the removed memory are
filled with 0FD.
2) All page structs are filled with 0xFD on PT/PMD, PT/PMD can be
cleared. In this case, the page used as PT/PMD can be freed.
For direct mapping pages, update direct_pages_count[level] when we freed
their pagetables. And do not free the pages again because they were
freed when offlining.
For vmemmap pages, free the pages and their pagetables.
For larger pages, do not split them into smaller ones because there is
no way to know if the larger page has been split. As a result, there is
no way to decide when to split. We deal the larger pages in the
following way:
1) For direct mapped pages, all the pages were freed when they were
offlined. And since menmory offline is done section by section, all
the memory ranges being removed are aligned to PAGE_SIZE. So only need
to deal with unaligned pages when freeing vmemmap pages.
2) For vmemmap pages being used to store page_struct, if part of the
larger page is still in use, just fill the unused part with 0xFD. And
when the whole page is fulfilled with 0xFD, then free the larger page.

For removing memmap region of sparse-vmemmap which is allocated bootmem,
memmap region of sparse-vmemmap needs to be registered by
get_page_bootmem(). So the patch searches pages of virtual mapping and
registers the pages by get_page_bootmem().
NOTE: register_page_bootmem_memmap() is not implemented for ia64,
ppc, s390, and sparc. So introduce CONFIG_HAVE_BOOTMEM_INFO_NODE
and revert register_page_bootmem_info_node() when platform doesn't
support it.
It's implemented by adding a new Kconfig option named
CONFIG_HAVE_BOOTMEM_INFO_NODE, which will be automatically selected
by memory-hotplug feature fully supported archs(currently only on
x86_64).
Since we have 2 config options called MEMORY_HOTPLUG and
MEMORY_HOTREMOVE used for memory hot-add and hot-remove separately,
and codes in function register_page_bootmem_info_node() are only
used for collecting infomation for hot-remove, so reside it under
MEMORY_HOTREMOVE.
Besides page_isolation.c selected by MEMORY_ISOLATION under
MEMORY_HOTPLUG is also such case, move it too.

Allocating a file structure in function get_empty_filp() might fail because
of several reasons:
- not enough memory for file structures
- operation is not allowed
- user is over its limit
Currently the function returns NULL in all cases and we loose the exact
reason of the error. All callers of get_empty_filp() assume that the function
can fail with ENFILE only.
Return error through pointer. Change all callers to preserve this error code.

With commit 8170e6bed4 ("x86, 64bit: Use a #PF handler to materialize
early mappings on demand") we started hitting an early bootup crash
where the Xen hypervisor would inform us that:
(XEN) d7:v0: unhandled page fault (ec=0000)
(XEN) Pagetable walk from ffffea000005b2d0:
(XEN) L4[0x1d4] = 0000000000000000 ffffffffffffffff
(XEN) domain_crash_sync called from entry.S
(XEN) Domain 7 (vcpu#0) crashed on cpu#3:
(XEN) ----[ Xen-4.2.0 x86_64 debug=n Not tainted ]----
.. that Xen was unable to context switch back to dom0.
Looking at the calling stack we find:
[<ffffffff8103feba>] xen_get_user_pgd+0x5a <--
[<ffffffff8103feba>] xen_get_user_pgd+0x5a
[<ffffffff81042d27>] xen_write_cr3+0x77
[<ffffffff81ad2d21>] init_mem_mapping+0x1f9
[<ffffffff81ac293f>] setup_arch+0x742
[<ffffffff81666d71>] printk+0x48
We are trying to figure out whether we need to up-date the user PGD as
well. Please keep in mind that under 64-bit PV guests we have a limited
amount of rings: 0 for the Hypervisor, and 1 for both the Linux kernel
and user-space. As such the Linux pvops'fied version of write_cr3
checks if it has to update the user-space cr3 as well.
That clearly is not needed during early bootup. The recent changes (see
above git commit) streamline the x86 page table allocation to be much
simpler (And also incidentally the #PF handler ends up in spirit being
similar to how the Xen toolstack sets up the initial page-tables).
The fix is to have an early-bootup version of cr3 that just loads the
kernel %cr3. The later version - which also handles user-page
modifications will be used after the initial page tables have been
setup.
[ hpa: removed a redundant #ifdef and made the new function __init.
Also note that x86-32 already has such an early xen_write_cr3. ]

An architecture should not unconditionally enable 'GENERIC_GPIO'
without providing an implementation. In case of arm64, selecting

lets us enable GPIOLIB when configuring the kernel, and that

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()."

This provides a band-aid to provide stable page writes on jbd without
needing to backport the fixed locking and page writeback bit handling
schemes of jbd2. The band-aid works by using bounce buffers to snapshot
page contents instead of waiting.
For those wondering about the ext3 bandage -- fixing the jbd locking
(which was done as part of ext4dev years ago) is a lot of surgery, and
setting PG_writeback on data pages when we actually hold the page lock
dropped ext3 performance by nearly an order of magnitude. If we're
going to migrate iscsi and raid to use stable page writes, the
complaints about high latency will likely return. We might as well
centralize their page snapshotting thing to one place.

On cris-linux-gcc, __SIZE_TYPE__ expands to "unsigned int", as
gcc-4.6.3-nolibc/cris-linux/lib/gcc/cris-linux/4.6.3/plugin/include/config/cris/linux.h
has
#define SIZE_TYPE "unsigned int"
Hence __kernel_size_t is also "unsigned int". But __kernel_ssize_t is
"long", which has a different base type, causing compiler warnings like:
fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat]
To fix this, __kernel_ssize_t should be changed to "int". Hence cris can
just use the generic 32-bit versions from include/asm-generic/posix_types.h
for all size-related types.

This contains parts of the ARM KVM support that have dependencies on
other patches merged through the arm-soc tree. In combination with
patches coming through Russell's tree, this will finally add full
support for the kernel based virtual machine on ARM, which has
been awaited for some time now.
Further, we now have a separate platform for virtual machines
and qemu booting that is used by both Xen and KVM, separating
these from the Versatile Express reference implementation.
Obviously, this new platform is multiplatform capable so it
can be combined with existing machines in the same kernel.

Converting more ARM platforms to multiplatform support. This time, OMAP
gets converted, which is a major step since this is by far the largest
platform in terms of code size. The same thing happens to the vt8500
platform.

* Two mach/uncompress.h files are removed, the changes made to them
elsewhere can be discarded now.
* Moving the OMAP4 irq_match array has context clashes with turning
omap4_sar_ram_init into an omap_early_initcall()

Pull ARM SoC multiplatform support from Arnd Bergmann:
"Converting more ARM platforms to multiplatform support. This time,
OMAP gets converted, which is a major step since this is by far the
largest platform in terms of code size. The same thing happens to the
vt8500 platform."

the mach/id.h header and the cpu_is_u8500_family() function in it are
now gone.

This is another cleanup series, containing the move of the Renesas
SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
generic pinctrl subsystem, changing it over to the common interfaces in
the process.
Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
we're merging this large branch of pinctrl conversion through arm-soc,
even though it contains the corresponding conversions for arch/sh. Main
reason for this is tight dependencies (that will now mostly be broken)
between the arch/sh and mach-shmobile implementations.
There will be more of this in 3.10 to do device-tree bindings, but this
is the initial conversion.

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.
