The Kconfig entries for HEXAGON_VM and HEXAGON_ANGEL_TRAPS were added,

Pull ARM SoC fix from Olof Johansson:
 "A late-arriving fix for musb on OMAP4, resolving an issue where the
  musb IP won't be clocked and thus not functional.  Small in scope,
  most of the lines changed is a longish comment."

  ARM: OMAP4: hwmod data: make 'ocp2scp_usb_phy_phy_48m" as the main clock

I think we could just move the full vm_iomap_memory() function into
util.h or similar, but I didn't get any reply from anybody actually
using nommu even to this trivial patch, so I'm not going to touch it any
more than required.

Here's the fairly minimal stub to make the nommu case at least
potentially work.  It doesn't seem like anybody cares, though.

Pull late parisc fixes from Helge Deller:
 "I know it's *very* late in the 3.9 release cycle, but since there
  aren't that many people testing the parisc linux kernel, a few (for
  our port) critical issues just showed up a few days back for the first
  time.

  What's in it?
   - add missing __ucmpdi2 symbol, which is required for btrfs on 32bit
     kernel.
   - change kunmap() macro to static inline function.  This fixes a
     debian/gcc-4.4 build error.
   - add locking when doing PTE updates.  This fixes random userspace
     crashes.
   - disable (optional) -mlong-calls compiler option for modules, else
     modules can't be loaded at runtime.
   - a smart patch by Will Deacon which fixes 64bit put_user() warnings
     on 32bit kernel."
