The virtio_pci_freeze/restore are defined under CONFIG_PM but is used
by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under
CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but
CONFIG_PM_RUNTIME is, the following warning message appeared:
drivers/virtio/virtio_pci.c:770:12: warning: ‘virtio_pci_freeze’ defined but not used [-Wunused-function]
static int virtio_pci_freeze(struct device *dev)
^
drivers/virtio/virtio_pci.c:790:12: warning: ‘virtio_pci_restore’ defined but not used [-Wunused-function]
static int virtio_pci_restore(struct device *dev)

Fix it by changing CONFIG_PM to CONFIG_PM_SLEEP.

This reverts commit 318df36e57.
This commit caused Steven Rostedt's hackbench runs to run out of memory
due to a leak. As noted by Joonsoo Kim, it is buggy in the following
scenario:
"I guess, you may set 0 to all kmem caches's cpu_partial via sysfs,
doesn't it?
In this case, memory leak is possible in following case. Code flow of
possible leak is follwing case.
* in __slab_free()
1. (!new.inuse || !prior) && !was_frozen
2. !kmem_cache_debug && !prior
3. new.frozen = 1
4. after cmpxchg_double_slab, run the (!n) case with new.frozen=1
5. with this patch, put_cpu_partial() doesn't do anything,
because this cache's cpu_partial is 0
6. return
In step 5, leak occur"
And Steven does indeed have cpu_partial set to 0 due to RT testing.
Joonsoo is cooking up a patch, but everybody agrees that reverting this
for now is the right thing to do.

Some of my configs I test with have CONFIG_A11Y_BRAILLE_CONSOLE set.
When I started testing against v3.11-rc4 my console went bonkers. Using
ktest to bisect the issue, it came down to:
commit bbeddf52a "printk: move braille console support into separate
braille.[ch] files"
Looking into the patch I found the problem. It's with the return of
braille_register_console(). As anything other than NULL is considered a
failure.
But for those of us that have CONFIG_A11Y_BRAILLE_CONSOLE set but do not
define a "brl" or "brl=" on the command line, we still may want a
console that those with sight can still use.
Return NULL (success) if "brl" or "brl=" is not on the console line.

This reverts commit fab840fc2d.
This commit even has the test-case to prove that the tracee
can be killed by SIGTRAP if the debugger does not remove the
breakpoints before PTRACE_DETACH.
However, this is exactly what wineserver deliberately does,
set_thread_context() calls PTRACE_ATTACH + PTRACE_DETACH just
for PTRACE_POKEUSER(DR*) in between.
So we should revert this fix and document that PTRACE_DETACH
should keep the breakpoints.

unshare_userns(new_cred) does *new_cred = prepare_creds() before
create_user_ns() which can fail. However, the caller expects that
it doesn't need to take care of new_cred if unshare_userns() fails.
We could change the single caller, sys_unshare(), but I think it
would be more clean to avoid the side effects on failure, so with
this patch unshare_userns() does put_cred() itself and initializes
*new_cred only if create_user_ns() succeeeds.

register that needs to be synced as its parameter. But the last call to
regcache_sync_block_raw_flush() in regcache_sync_block_raw() passes the address
of the last register in the block. This effectively always skips over the last
register in a block, even if it needs to be synced. In order to fix it increase
the address by one register.
The issue was introduced in commit 75a5f89 ("regmap: cache: Write consecutive
registers in a single block write").

As comment in include/uapi/asm-generic/fcntl.h described, when
introducing new O_* bits, we need to check its uniqueness in
fcntl_init(). But __O_TMPFILE bit is missing. So fix it.

Every now and then someone proposes a new flink syscall, and this spawns
a long discussion of whether it would be a security problem. I think
that this is missing the point: flink is *already* allowed without
privilege as long as /proc is mounted -- it's called AT_SYMLINK_FOLLOW.
Now that O_TMPFILE is here, the ability to create a file with O_TMPFILE,
write it, and link it in is very convenient. The only problem is that
it requires that /proc be mounted so that you can do:
linkat(AT_FDCWD, "/proc/self/fd/<tmpfd>", dfd, path, AT_SYMLINK_NOFOLLOW)
This sucks -- it's much nicer to do:
linkat(tmpfd, "", dfd, path, AT_EMPTY_PATH)
Let's allow it.
If this turns out to be excessively scary, it we could instead require
that the inode in question be I_LINKABLE, but this seems pointless given
the /proc situation

O_TMPFILE, like O_CREAT, should respect the requested mode and should
create regular files.
This fixes two bugs: O_TMPFILE required privilege (because the mode
ended up as 000) and it produced bogus inodes with no type.

Since remove_proc_entry() started to wait for IO in progress (i.e.
since 2007 or so), the locking in fs/reiserfs/proc.c became wrong;
if procfs read happens between the moment when umount() locks the
victim superblock and removal of /proc/fs/reiserfs/<device>/*,
we'll get a deadlock - read will wait for s_umount (in sget(),
called by r_start()), while umount will wait in remove_proc_entry()
for that read to finish, holding s_umount all along.
Fortunately, the same change allows a much simpler race avoidance -
all we need to do is remove the procfs entries in the very beginning
of reiserfs ->kill_sb(); that'll guarantee that pointer to superblock
will remain valid for the duration for procfs IO, so we don't need
sget() to keep the sucker alive. As the matter of fact, we can
get rid of the home-grown iterator completely, and use single_open()
instead.

The hardware interrupt routing for boot CPU != 0 is wrong because it
will route all the hardware interrupts to TP0 which is not the one we
booted from. Fix this by properly checking which boot CPU we are booting
from and updating the right interrupt mask for the boot CPU. This fixes
booting on BCM3368 with bmips_smp_emabled = 0.

This patch removes sti_secondary_start from _INIT section, there are 2
reason for this removal.
1. discarding such a small code does not save much, given the RAM

2. Having this code discarded, creates corruption issue when we boot

Due to wrong older revision of documentation used as reference, we
seem to have a bunch of LDOs wrongly configured on OMAP5 uEVM. This
series is based power tree on production board 750-2628-XXX platform.
Unfortunately, the wrong voltages may be detrimental to OMAP5 as they
supply hardware blocks at voltages that are out of specification.
There is a chance that without these fixes there can be hardware
damage to omap5-uevm boards with the v3.11-rc series.
