git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fix from Tejun Heo:
"The lifetime rules of cgroup hierarchies always have been somewhat
counter-intuitive and cgroup core tried to enforce that hierarchies
w/o userland-visible usages must die in finite amount of time so that
the controllers can be reused for other hierarchies; unfortunately,
this can't be implemented reasonably for the memory controller - the
kmemcg part doesn't have any way to forcefully drain the existing
usages, leading to an interruptible hang if a following mount attempts
to use the controller in any way.
So, it seems like we're stuck with "hierarchies live on till they die
whenever that may be" at least for now. This pretty much confines
attaching controllers to hierarchies to before the hierarchies are
actively used by making dynamic configurations post active usages
unreliable. This has never been reliable and should be fine in
practice given how cgroups are used.
After the patch, hierarchies aren't killed if it isn't already
drained. A following mount attempt of the same mount options will
reuse the existing hierarchy. Mount attempts with differing options
will fail w/ -EBUSY"

Commit e61734c55c24 ("cgroup: remove cgroup->name") added two extra
newlines to memcg oom kill log messages. This makes dmesg hard to read
and parse. The issue affects 3.15+.
Example:
Task in /t <<< extra #1
killed as a result of limit of /t
<<< extra #2
memory: usage 102400kB, limit 102400kB, failcnt 274712
Remove the extra newlines from memcg oom kill messages, so the messages
look like:
Task in /t killed as a result of limit of /t
memory: usage 102400kB, limit 102400kB, failcnt 240649

The OOM killing invocation does a lot of duplicative checks against the
task's allocation context. Rework it to take advantage of the existing
checks in the allocator slowpath.
The OOM killer is invoked when the allocator is unable to reclaim any
pages but the allocation has to keep looping. Instead of having a check
for __GFP_NORETRY hidden in oom_gfp_allowed(), just move the OOM
invocation to the true branch of should_alloc_retry(). The __GFP_FS
check from oom_gfp_allowed() can then be moved into the OOM avoidance
branch in __alloc_pages_may_oom(), along with the PF_DUMPCORE test.
__alloc_pages_may_oom() can then signal to the caller whether the OOM
killer was invoked, instead of requiring it to duplicate the order and
high_zoneidx checks to guess this when deciding whether to continue.

Commit ffcc393641 ("dm: enhance internal suspend and resume interface")
attempted to handle multiple internal suspends on the same device, but
it did that incorrectly. When these functions are called in this order
on the same device the device is no longer suspended, but it should be:
dm_internal_suspend_noflush
dm_internal_suspend_noflush
dm_internal_resume
Fix this bug by maintaining an 'internal_suspend_count' and resuming
the device when this count drops to zero.

Pull two arm64 fixes from Will Deacon:
"Arm64 fixes seem to come in pairs recently. We've got a fix for
removing device-tree blobs when doing a make clean and another one
addressing a missing include, which fixes build failures in -next for
allmodconfig (spotted by Mark's buildbot).
Summary from signed tag:
- fix cleaning of .dtbs following directory restructuring
- fix allmodconfig build breakage in -next due to missing include"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: dump: Fix implicit inclusion of definition for PCI_IOBASE
arm64: Add dtb files to archclean rule

This reverts commit 02b2aaaa57ab41504e8d03a3b2ceeb9440a2c188.
This interface was determined to be flawed and required too invasive a
fix for the RC cycle. This will be revisited in 3.20.

Introduce a new variable to count the number of allocated migration
structures. The existing variable cache->nr_migrations became
overloaded. It was used to:
i) track of the number of migrations in flight for the purposes of
quiescing during suspend.
ii) to estimate the amount of background IO occuring.
Recent discard changes meant that REQ_DISCARD bios are processed with
a migration. Discards are not background IO so nr_migrations was not
incremented. However this could cause quiescing to complete early.
(i) is now handled with a new variable cache->nr_allocated_migrations.
cache->nr_migrations has been renamed cache->nr_io_migrations.
cleanup_migration() is now called free_io_migration(), since it
decrements that variable.
Also, remove the unused cache->next_migration variable that got replaced
with with prealloc_structs a while ago.

If a DM table is reloaded with an inactive table when the device is not
suspended (normal procedure for LVM2), then there will be two dm-bufio
objects that can diverge. This can lead to a situation where the
inactive table uses bufio to read metadata at the same time the active
table writes metadata -- resulting in the inactive table having stale
metadata buffers once it is promoted to the active table slot.
Fix this by using reference counting and a global list of cache metadata
objects to ensure there is only one metadata object per metadata device.

SYSENTER emulation is broken in several ways:
1. It misses the case of 16-bit code segments completely (CVE-2015-0239).
2. MSR_IA32_SYSENTER_CS is checked in 64-bit mode incorrectly (bits 0 and 1 can
still be set without causing #GP).
3. MSR_IA32_SYSENTER_EIP and MSR_IA32_SYSENTER_ESP are not masked in
legacy-mode.
4. There is some unneeded code.
Fix it.

Since c9465b4ec37a68425 (arm64: add support to dump the kernel page tables)
allmodconfig has failed to build on arm64 as a result of:
../arch/arm64/mm/dump.c:55:20: error: 'PCI_IOBASE' undeclared here (not in a function)
Fix this by explicitly including io.h to ensure that a definition is
present.

Many users see this message when booting without knowning that it is
of no importance and that TSC calibration may have succeeded by
another way.
As explained by Paul Bolle in
http://lkml.kernel.org/r/[email protected]
"Fast TSC calibration failed" should not be considered as an error
since other calibration methods are being tried afterward. At most,
those send a warning if they fail (not an error). So let's change
the message from error to warning.
[ tglx: Make if pr_info. It's really not important at all ]
