  8. 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.

  10. 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.

  11. drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed r…

    …tc 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.

  7. memcg: fix hierarchical oom locking

    Commit 79dfdac ("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.

  10. 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.

  11. vmscan: clear ZONE_CONGESTED for zone with good watermark

    ZONE_CONGESTED is only cleared in kswapd, but pages can be freed in any
    task.  It's possible ZONE_CONGESTED isn't cleared in some cases:
    
     1. the zone is already balanced just entering balance_pgdat() for
        order-0 because concurrent tasks free memory.  In this case, later
        check will skip the zone as it's balanced so the flag isn't cleared.
    
     2. high order balance fallbacks to order-0.  quote from Mel: At the
        end of balance_pgdat(), kswapd uses the following logic;
    
    	If reclaiming at high order {
    		for each zone {
    			if all_unreclaimable
    				skip
    			if watermark is not met
    				order = 0
    				loop again
    
    			/* watermark is met */
    			clear congested
    		}
    	}
    
        i.e. it clears ZONE_CONGESTED if it the zone is balanced.  if not,
        it restarts balancing at order-0.  However, if the higher zones are
        balanced for order-0, kswapd will miss clearing ZONE_CONGESTED as
        that only happens after a zone is shrunk.  This can mean that
        wait_iff_congested() stalls unnecessarily.
    
    This patch makes kswapd clear ZONE_CONGESTED during its initial
    highmem->dma scan for zones that are already balanced.

  12. kernel/printk: do not turn off bootconsole in printk_late_init() if k…

    …eep_bootcon
    
    It seems that 7bf6939 ("console: allow to retain boot console via
    boot option keep_bootcon") doesn't always achieve what it aims, as when
    printk_late_init() runs it unconditionally turns off all boot consoles.
    With this patch, I am able to see more messages on the boot console in
    KVM guests than I can without, when keep_bootcon is specified.
    
    I think it is appropriate for the relevant -stable trees.  However, it's
    more of an annoyance than a serious bug (ideally you don't need to keep
    the boot console around as console handover should be working -- I was
    encountering a situation where the console handover wasn't working and
    not having the boot console available meant I couldn't see why).

    sched_clock() can't be used with preempt enabled.  And we don't need
    fast approach to get clock here, so let's use ktime API.

  18. memcg: pin execution to current cpu while draining stock

    Commit d1a05b6 ("memcg do not try to drain per-cpu caches without
    pages") added a drain_local_stock() call to a preemptible section.
    
    The draining task looks up the cpu-local stock twice to set the
    draining-flag, then to drain the stock and clear the flag again.  If the
    task is migrated to a different CPU in between, noone will clear the
    flag on the first stock and it will be forever undrainable.  Its charge
    can not be recovered and the cgroup can not be deleted anymore.
    
    Properly pin the task to the executing CPU while draining stocks.
