Use the domain's maximum reservation to limit the amount of extra RAM

xfs: fix xfs_mark_inode_dirty during umount
During umount we do not add a dirty inode to the lru and wait for it to
become clean first, but force writeback of data and metadata with
I_WILL_FREE set. Currently there is no way for XFS to detect that the
inode has been redirtied for metadata operations, as we skip the
mark_inode_dirty call during teardown. Fix this by setting i_update_core
nanually in that case, so that the inode gets flushed during inode reclaim.
Alternatively we could enable calling mark_inode_dirty for inodes in
I_WILL_FREE state, and let the VFS dirty tracking handle this. I decided
against this as we will get better I/O patterns from reclaim compared to
the synchronous writeout in write_inode_now, and always marking the inode
dirty in some way from xfs_mark_inode_dirty is a better safetly net in
either case.

ext4: remove i_mutex lock in ext4_evict_inode to fix lockdep complaining
The i_mutex lock and flush_completed_IO() added by commit
2581fdc810
in ext4_evict_inode() causes lockdep complaining about potential
deadlock in several places. In most/all of these LOCKDEP complaints
it looks like it's a false positive, since many of the potential
circular locking cases can't take place by the time the
ext4_evict_inode() is called; but since at the very least it may mask
real problems, we need to address this.
This change removes the flush_completed_IO() and i_mutex lock in
ext4_evict_inode(). Instead, we take a different approach to resolve
the software lockup that commit
2581fdc810 intends to fix. Rather
than having ext4-dio-unwritten thread wait for grabing the i_mutex
lock of an inode, we use mutex_trylock() instead, and simply requeue
the work item if we fail to grab the inode's i_mutex lock.
This should speed up work queue processing in general and also
prevents the following deadlock scenario: During page fault,
shrink_icache_memory is called that in turn evicts another inode B.
Inode B has some pending io_end work so it calls ext4_ioend_wait()
that waits for inode B's i_ioend_count to become zero. However, inode
B's ioend work was queued behind some of inode A's ioend work on the
same cpu's ext4-dio-unwritten workqueue. As the ext4-dio-unwritten
thread on that cpu is processing inode A's ioend work, it tries to
grab inode A's i_mutex lock. Since the i_mutex lock of inode A is
still hold before the page fault happened, we enter a deadlock.

sparc32,sun4d: Change IPI IRQ level to prevent collision between IPI and timer interrupt
On Sun4d systems running in SMP mode, IRQ 14 is used for timer interrupts
and has a specialized interrupt handler. IPI is currently set to use IRQ 14
as well, which causes it to trigger the timer interrupt handler, and not the
IPI interrupt handler.
The IPI interrupt is therefore changed to IRQ 13, which is the highest
normally handled interrupt. This IRQ is also used for SBUS interrupts,
however there is nothing in the IPI/SBUS interrupt handlers that indicate
that they will not handle sharing the interrupt.
(IRQ 13 is indicated as audio interrupt, which is unlikely to be found in a
sun4d system)

ARM: mach-shmobile: Remove 3DG/SGX from sh7372 INTCS
This patch removes support for the SGX interrupt source in
the sh7372 INTCS controller.
The SGX hardware block included in sh7372 is already hooked
up to the ARM Cortex-A8 core using the INTCA controller,
so SGX users are encouraged to make use of that interrupt
source instead.
Removing support for the SGX interrupt source in INTCS
simplifies the sh7372 power management code by allowing
us to assume that only INTCA needs to be powered on to
operate the SGX hardware.
If the INTCS interrupt source would be kept then the kernel
would be forced to deal with additional dependencies that does
not follow the regular power domain hiearachy. With this
patch in place we can safely power down INTCS while the
SGX is operating.

sfi: table irq 0xFF means 'no interrupt'
According to the SFI specification irq number 0xFF means device has no
interrupt or interrupt attached via GPIO.
Currently, we don't handle this special case and set irq field in
*_board_info structs to 255. It leads to confusion in some drivers.
Accelerometer driver tries to register interrupt 255, fails and prints
"Cannot get IRQ" to dmesg.

arch/powerpc/sysdev/fsl_rio.c: correct IECSR register clear value
This bug causes the IECSR register clear failure. In this case, the RETE
(retry error threshold exceeded) interrupt will be generated and cannot be
cleared. So the related ISR may be called persistently.
The RETE bit in IECSR is cleared by writing a 1 to it.

drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq.
The previous rtc-s3c had two issues related with its IRQ.
1. Users cannot open rtc multiple times because an open operation
calls request_irq on the same IRQ. (e.g., two user processes wants to
open and read RTC time from rtc-s3c at the same time)
2. If alarm is set and no one has the rtc opened with filesystem
(either the alarm is set by kernel/boot-loader or user set an alarm and
closed rtc dev file), the pending bit is not cleared and no further
interrupt is invoked. When the alarm is used by the system itself such
as a resume from suspend-to-RAM or other Low-power modes/idle, this is
a critical issue.
This patch mitigates these issues by calling request_irq at probe and
free_irq at remove.

memcg: fix hierarchical oom locking
Commit
79dfdaccd1d5 ("memcg: make oom_lock 0 and 1 based rather than
counter") tried to oom lock the hierarchy and roll back upon
encountering an already locked memcg.
The code is confused when it comes to detecting a locked memcg, though,
so it would fail and rollback after locking one memcg and encountering
an unlocked second one.
The result is that oom-locking hierarchies fails unconditionally and
that every oom killer invocation simply goes to sleep on the oom
waitqueue forever. The tasks practically hang forever without anyone
intervening, possibly holding locks that trip up unrelated tasks, too.

rapidio: fix use of non-compatible registers
Replace/remove use of RIO v.1.2 registers/bits that are not
forward-compatible with newer versions of RapidIO specification.
RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR,
Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR.
Use of removed (since RIO v.1.3) register bits affects users of
currently available 1.3 and 2.x compliant devices who may use not so
recent kernel versions.
Removing checks for unsupported bits makes corresponding routines
compatible with all versions of RapidIO specification. Therefore,
backporting makes stable kernel versions compliant with RIO v.1.3 and
later as well.
