drm/ttm: device address space != CPU address space
We need to store device offsets in 64 bit as the device
address space may be larger than the CPU's.
Fixes GPU init failures on radeons with 4GB or more of
vram on 32 bit kernels. We put vram at the start of the
GPU's address space so the gart aperture starts at 4 GB
causing all GPU addresses in the gart aperture to get
truncated.

drm/mm: Support 4 GiB and larger ranges
The current implementation is limited by the number of addresses that
fit into an unsigned long. This causes problems on 32-bit Tegra where
unsigned long is 32-bit but drm_mm is used to manage an IOVA space of
4 GiB. Given the 32-bit limitation, the range is limited to 4 GiB - 1
(or 4 GiB - 4 KiB for page granularity).
This commit changes the start and size of the range to be an unsigned
64-bit integer, thus allowing much larger ranges to be supported.

locking/rtmutex: Set state back to running on error
The "usual" path is:
- rt_mutex_slowlock()
- set_current_state()
- task_blocks_on_rt_mutex() (ret 0)
- __rt_mutex_slowlock()
- sleep or not but do return with __set_current_state(TASK_RUNNING)
- back to caller.
In the early error case where task_blocks_on_rt_mutex() return
-EDEADLK we never change the task's state back to RUNNING. I
assume this is intended. Without this change after ww_mutex
using rt_mutex the selftest passes but later I get plenty of:

mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED defines
Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page
table levels folded. Usually, these defines are provided by
<asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>.
But some architectures fold page table levels in a custom way. They
need to define these macros themself. This patch adds missing defines.
The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc()
and __pud_alloc() on architectures without these page table levels.

nilfs2: fix potential memory overrun on inode
Each inode of nilfs2 stores a root node of a b-tree, and it turned out to
have a memory overrun issue:
Each b-tree node of nilfs2 stores a set of key-value pairs and the number
of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as
a few other "bn_*" members.
Since the value of "bn_nchildren" is used for operations on the key-values
within the b-tree node, it can cause memory access overrun if a large
number is incorrectly set to "bn_nchildren".
For instance, nilfs_btree_node_lookup() function determines the range of
binary search with it, and too large "bn_nchildren" leads
nilfs_btree_node_get_key() in that function to overrun.
As for intermediate b-tree nodes, this is prevented by a sanity check
performed when each node is read from a drive, however, no sanity check
has been done for root nodes stored in inodes.
This patch fixes the issue by adding missing sanity check against b-tree
root nodes so that it's called when on-memory inodes are read from ifile,
inode metadata file.

memcg: fix low limit calculation
A memcg is considered low limited even when the current usage is equal to
the low limit. This leads to interesting side effects e.g.
groups/hierarchies with no memory accounted are considered protected and
so the reclaim will emit MEMCG_LOW event when encountering them.
Another and much bigger issue was reported by Joonsoo Kim. He has hit a
NULL ptr dereference with the legacy cgroup API which even doesn't have
low limit exposed. The limit is 0 by default but the initial check fails
for memcg with 0 consumption and parent_mem_cgroup() would return NULL if
use_hierarchy is 0 and so page_counter_read would try to dereference NULL.
I suppose that the current implementation is just an overlook because the
documentation in Documentation/cgroups/unified-hierarchy.txt says:
"The memory.low boundary on the other hand is a top-down allocated
reserve. A cgroup enjoys reclaim protection when it and all its
ancestors are below their low boundaries"
Fix the usage and the low limit comparision in mem_cgroup_low accordingly.

Unable to allocate RAM for process text/data, errno 12 SEGV
This problem happens because we allocate ordered page through
__get_free_pages() in do_mmap_private() in some cases and we try to free
individual pages rather than ordered page in free_page_series(). In
this case, freeing pages whose refcount is not 0 won't be freed to the
page allocator so memory leak happens.
To fix the problem, this patch changes __get_free_pages() to
alloc_pages_exact() since alloc_pages_exact() returns
physically-contiguous pages but each pages are refcounted.

Commit:
1e02ce4cccdc ("x86: Store a per-cpu shadow copy of CR4")
added a shadow CR4 such that reads and writes that do not
modify the CR4 execute much faster than always reading the
register itself.
The change modified cpu_init() in common.c, so that the
shadow CR4 gets initialized before anything uses it.
Unfortunately, there's two cpu_init()s in common.c. There's
one for 64-bit and one for 32-bit. The commit only added
the shadow init to the 64-bit path, but the 32-bit path
needs the init too.

ARM64 CPUidle driver requires the cpu_do_idle function so that it can

The current ARM64 CPUidle driver does not include asm/proc-fns.h
explicitly and it has so far relied on implicit inclusion from other
header files.
Owing to some header dependencies reshuffling this currently triggers
build failures when CONFIG_ARM64_64K_PAGES=y:

This patch adds the explicit inclusion of the asm/proc-fns.h header file
in the arm64 asm/cpuidle.h header file, so that the build breakage is fixed
and the required header inclusion is added to the appropriate arch back-end
CPUidle header, already included by the CPUidle arm64 driver, where
CPUidle arch related function declarations belong.

arm64: compat Fix siginfo_t -> compat_siginfo_t conversion on big endian
The native (64-bit) sigval_t union contains sival_int (32-bit) and

takes a sigval_t value (as part of a larger structure, e.g.
compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t
union is converted to the native sigval_t with sival_int overlapping
with either the least or the most significant half of sival_ptr,
depending on endianness. When the corresponding signal is delivered to a
compat application, on big endian the current (compat_uptr_t)sival_ptr
cast always returns 0 since sival_int corresponds to the top part of
sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int

This is triggered by the use of virt_to_page() on a module address,
which ends to pointing to Nowhereland if you're lucky, or corrupt
your precious data if not.
This patch fixes the logic by mimicking what is done on arm:
- If we're patching a module and CONFIG_DEBUG_SET_MODULE_RONX is set,
use vmalloc_to_page().
- If we're patching the kernel and CONFIG_DEBUG_RODATA is set,
use virt_to_page().
- Otherwise, use the provided address, as we can write to it directly.

At the same time, disable inline expansion of the core AES functions,

arm64: psci: move psci firmware calls out of line
An arm64 allmodconfig fails to build with GCC 5 due to __asmeq
assertions in the PSCI firmware calling code firing due to mcount
preambles breaking our assumptions about register allocation of function
arguments:
/tmp/ccDqJsJ6.s: Assembler messages:
/tmp/ccDqJsJ6.s:60: Error: .err encountered

This patch fixes the issue by moving the PSCI calls out-of-line into
their own assembly files, which are safe from the compiler's meddling
fingers.

arm64: vdso: minor ABI fix for clock_getres
The vdso implementation of clock_getres currently returns 0 (success)
whenever a null timespec is provided by the caller, regardless of the
clock id supplied.
This behavior is incorrect. It should fall back to syscall when an
unrecognized clock id is passed, even when the timespec argument is
null. This ensures that clock_getres always returns an error for
invalid clock ids.

perf tools: Fix probing for PERF_FLAG_FD_CLOEXEC flag
Commit
f6edb53c4993ffe92ce521fb449d1c146cea6ec2 converted the probe to
a CPU wide event first (pid == -1). For kernels that do not support
the PERF_FLAG_FD_CLOEXEC flag the probe fails with EINVAL. Since this
errno is not handled pid is not reset to 0 and the subsequent use of
pid = -1 as an argument brings in an additional failure path if
perf_event_paranoid > 0:
$ perf record -- sleep 1
perf_event_open(..., 0) failed unexpectedly with error 13 (Permission denied)
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.007 MB /tmp/perf.data (11 samples) ]
Also, ensure the fd of the confirmation check is closed and comment why
pid = -1 is used.
