      genirq: Add sanity checks for PM options on shared interrupt lines · cab303be
      Thomas Gleixner authored
      Account the IRQF_NO_SUSPEND and IRQF_RESUME_EARLY actions on shared
      interrupt lines and yell loudly if there is a mismatch.

      Thomas Gleixner authored
      No functional change. Preparatory patch for cleaning up the suspend
      abort functionality. Update the comments while at it.

      PM / sleep: Mechanism for aborting system suspends unconditionally · 068765ba
      Rafael J. Wysocki authored
      It sometimes may be necessary to abort a system suspend in
      progress or wake up the system from suspend-to-idle even if the
      pm_wakeup_event()/pm_stay_awake() mechanism is not enabled.
      
      For this purpose, introduce a new global variable pm_abort_suspend
      and make pm_wakeup_pending() check its value.  Also add routines
      for manipulating that variable.

      Pull Xtensa updates from Chris Zankel:
       "Xtensa improvements for 3.17:
         - support highmem on cores with aliasing data cache.  Enable highmem
           on kc705 by default
         - simplify addition of new core variants (no need to modify Kconfig /
           Makefiles)
         - improve robustness of unaligned access handler and its interaction
           with window overflow/underflow exception handlers
         - deprecate atomic and spill registers syscalls
         - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
           statements
         - wire up renameat2 syscall.
      
        Various fixes:
         - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
         - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
         - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
           (runtime unrecoverable exception)
         - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
           register clobbering)
         - fix kernel/user jump out of fast_unaligned (potential runtime
           unrecoverabl exception)
         - replace termios IOCTL code definitions with constants (userspace
           build breakage)"

      This code never even compiled.  Reverting the patch does not work, since

      Pull ARM SoC fixes from Olof Johansson:
       "Here's the weekly batch of fixes from arm-soc.
      
        The delta is a largeish negative delta, due to revert of SMP support
        for Broadcom's STB SoC -- it was accidentally merged before some
        issues had been addressed, so they will make a new attempt for 3.18.
        I didn't see a need for a full revert of the whole platform due to
        this, we're keeping the rest enabled.
      
        The rest is mostly:
      
         - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
         - some MTD/NAND fixes for OMAP
         - minor DT fixes for shmobile
         - warning fix for UP builds on vexpress/spc
      
        There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
        so it can boot.  Drivers and the rest had landed for 3.17, and it's
        small and isolated so it made sense to pick up now even if it's not a
        bugfix"
