Fix clashing values for O_PATH and FMODE_NONOTIFY on sparc. The
clashing O_PATH value was added in commit 5229645bdc35 ("vfs: add
nonconflicting values for O_PATH") but this can't be changed as it is
user-visible.
FMODE_NONOTIFY is only used internally in the kernel, but it is in the
same numbering space as the other O_* flags, as indicated by the comment
at the top of include/uapi/asm-generic/fcntl.h (and its use in
fs/notify/fanotify/fanotify_user.c). So renumber it to avoid the clash.
All of this has happened before (commit 12ed2e36c98a: "fanotify:
FMODE_NONOTIFY and __O_SYNC in sparc conflict"), and all of this will
happen again -- so update the uniqueness check in fcntl_init() to
include __FMODE_NONOTIFY.

link file
In ocfs2_link(), the parent directory inode passed to function
ocfs2_lookup_ino_from_name() is wrong. Parameter dir is the parent of
new_dentry not old_dentry. We should get old_dir from old_dentry and
lookup old_dentry in old_dir in case another node remove the old dentry.
With this change, hard linking works again, when paths are relative with
at least one subdirectory. This is how the problem was reproducable:
# mkdir a
# mkdir b
# touch a/test
# ln a/test b/test
ln: failed to create hard link `b/test' => `a/test': No such file or directory
However when creating links in the same dir, it worked well.
Now the link gets created.

Tejun, while reviewing the code, spotted the following race condition
between the dirtying and truncation of a page:
__set_page_dirty_nobuffers() __delete_from_page_cache()
if (TestSetPageDirty(page))
page->mapping = NULL
if (PageDirty())
dec_zone_page_state(page, NR_FILE_DIRTY);
dec_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE);
if (page->mapping)
account_page_dirtied(page)
__inc_zone_page_state(page, NR_FILE_DIRTY);
__inc_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE);
which results in an imbalance of NR_FILE_DIRTY and BDI_RECLAIMABLE.
Dirtiers usually lock out truncation, either by holding the page lock
directly, or in case of zap_pte_range(), by pinning the mapcount with
the page table lock held. The notable exception to this rule, though,
is do_wp_page(), for which this race exists. However, do_wp_page()
already waits for a locked page to unlock before setting the dirty bit,
in order to prevent a race where clear_page_dirty() misses the page bit
in the presence of dirty ptes. Upgrade that wait to a fully locked
set_page_dirty() to also cover the situation explained above.
Afterwards, the code in set_page_dirty() dealing with a truncation race
is no longer needed. Remove it.

Constantly forking task causes unlimited grow of anon_vma chain. Each
next child allocates new level of anon_vmas and links vma to all
previous levels because pages might be inherited from any level.
This patch adds heuristic which decides to reuse existing anon_vma
instead of forking new one. It adds counter anon_vma->degree which
counts linked vmas and directly descending anon_vmas and reuses anon_vma
if counter is lower than two. As a result each anon_vma has either vma
or at least two descending anon_vmas. In such trees half of nodes are
leafs with alive vmas, thus count of anon_vmas is no more than two times
bigger than count of vmas.
This heuristic reuses anon_vmas as few as possible because each reuse
adds false aliasing among vmas and rmap walker ought to scan more ptes
when it searches where page is might be mapped.

wait_consider_task() checks EXIT_ZOMBIE after EXIT_DEAD/EXIT_TRACE and
both checks can fail if we race with EXIT_ZOMBIE -> EXIT_DEAD/EXIT_TRACE
change in between, gcc needs to reload p->exit_state after
security_task_wait(). In this case ->notask_error will be wrongly
cleared and do_wait() can hang forever if it was the last eligible
child.
Many thanks to Arne who carefully investigated the problem.
Note: this bug is very old but it was pure theoretical until commit
b3ab03160dfa ("wait: completely ignore the EXIT_DEAD tasks"). Before
this commit "-O2" was probably enough to guarantee that compiler won't
read ->exit_state twice.

The introduction of the uapi directories in v3.7-rc1 moved some of the
generated headers from arch/*/include/generated to the uapi directory,
keeping the #include directives intact.
This creates a problem when bisecting, because the unversioned files are
not cleaned automatically by git and the compiler might include stale
headers as a result. Instead of cleaning them in the Makefiles, promote
arch/*/include/generated/uapi in the search path. Under normal
circumstances, there is no overlap between this uapi subdirectory and
its parent, so the include choices remain the same. We keep
arch/*/include/generated/uapi in the USERINCLUDE variable so that it is
usable standalone.
Note that we cannot completely swap the order of the uapi and
kernel-only directories, since the headers in include/uapi/asm-generic
are meant to be wrapped by their include/asm-generic counterparts when
building kernel code.

When perf report --children resorts output fields, it tries to put
caller above the callee. But this was only meaningful for a same thread
and doing this requires callchain enabled. So fix its check before
comparing the callchain depth.
This also changes the hist accumulation tests: In test 3, xmalloc in
bash thread should be above than other perf threads due to alphabetical
order of comm string. Also it's under page_fault in bash thread since
alphabetical order of dso name. The sys_perf_event_open in perf thread
is put on the last line since it's self overhead is 0.
In test 4, the sys_perf_event_open is put above other perf entries that
have same children overhead since its callchain depth is smaller.

The early ioremap support introduced by patch bf4b558eba92
("arm64: add early_ioremap support") failed to add a call to
early_ioremap_reset() at an appropriate time. Without this call,
invocations of early_ioremap etc. that are done too late will go
unnoticed and may cause corruption.
This is exactly what happened when the first user of this feature
was added in patch f84d02755f5a ("arm64: add EFI runtime services").
The early mapping of the EFI memory map is unmapped during an early
initcall, at which time the early ioremap support is long gone.
Fix by adding the missing call to early_ioremap_reset() to
setup_arch(), and move the offending early_memunmap() to right after
the point where the early mapping of the EFI memory map is last used.

AM437x Starter Kit already has discrete pullups
for all I2C buses, so we can (and should) remove
internal pulls.

This patch just makes USB[01]_DRVVBUS signal
explicitly muxed. Note that board already has
a discrete pulldown, so we're not adding any
pulls here.

AM437x Starter Kit already has discrete pulls
where they are necessary. It's safe (and actually
better) to remove internal pulls.

By don't relying on implicit MMC0 pulldown we
make sure that pins are marked busy and even
if we have a broken bootloader, MMC0 will
remain functional.

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
- Fix BUG() on !SMP builds
- Fix for OOPS on pre-NV50 that snuck into -next
- MCP7[789A] hang fix where firmware hasn't already setup NISO pollers
- NV4x IGP MSI disable, it doesn't appear to work correctly
- Add GK208B to recognised boards (no code change aside from adding
chipset recognition)
* 'linux-3.19' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:

The FSI2 sound node used the generic compatible property only.
Add the SoC-specific one, to make it future proof.

Now local variables kernel_x_start and kernel_x_end defined using
'unsigned long' type which is wrong because they represent physical
memory range and will be calculated wrongly if LPAE is enabled.
As result, all following code in map_lowmem() will not work correctly.
For example, Keystone 2 boot is broken because
kernel_x_start == 0x0000 0000
kernel_x_end == 0x0080 0000
instead of
kernel_x_start == 0x0000 0008 0000 0000
kernel_x_end == 0x0000 0008 0080 0000
and as result whole low memory will be mapped with MT_MEMORY_RW
permissions by code (start > kernel_x_end):
} else if (start >= kernel_x_end) {
map.pfn = __phys_to_pfn(start);
map.virtual = __phys_to_virt(start);
map.length = end - start;
map.type = MT_MEMORY_RW;
create_mapping(&map);
}
Hence, fix it by using phys_addr_t type for variables kernel_x_start
and kernel_x_end.
