      Pull pinctrl fixes from Linus Walleij:
       "This fixes a few pinctrl problems seen since v3.7-rc1:
         - Section tagging for init code
         - Use proper pointers to lookup struct device * in the bcm2835
           (a.k.a.  Raspberry Pi)
         - Remove duplicate #includes
         - Fix bad return values in errorpath
         - Remove extraneous pull function from the sirf driver causing build
           errors
         - Provide compilation stubs for the Nomadik pinctrl driver when used
           with legacy systems without PRCMU units
         - Various irqdomain fixes in the Nomadik driver as predicted
         - Various smallish bugs in the Tegra driver, most also targeted for
           stable
         - Removed a deadlocking mutex in the groups debugfs show function"
      
      * tag 'pinctrl-v3.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:

      ext4: Avoid underflow in ext4_trim_fs() · 5de35e8d
      Lukas Czerner authored
      Currently if len argument in ext4_trim_fs() is smaller than one block,
      the 'end' variable underflow. Avoid that by returning EINVAL if len is
      smaller than file system block.
      
      Also remove useless unlikely().

      KVM guest: exit idleness when handling KVM_PV_REASON_PAGE_NOT_PRESENT · c5e015d4
      Sasha Levin authored
      KVM_PV_REASON_PAGE_NOT_PRESENT kicks cpu out of idleness, but we haven't
      marked that spot as an exit from idleness.
      
      Not doing so can cause RCU warnings such as:
