Merge branch 'for-v3.4-rc5' of git://git./linux/kernel/git/paulg/linux

Pull build fixes for less mainstream architectures from Paul Gortmaker:
 "These are fixes for frv(1), blackfin(2), powerpc(1) and xtensa(4).

  Fortunately the touches are nearly all specific to files just used by
  the arch in question.  The two touches to shared/common files
  [kernel/irq/debug.h and drivers/pci/Makefile] are trivial to assess as
  no risk to anyone.

  Half of them relate to xtensa directly.  It was only when I fixed the
  last xtensa issue that I realized that the arch has been broken for a
  significant time, and isn't a specific v3.4 regression.  So if you
  wanted, we could leave xtensa lying bleeding in the street for a
  couple more weeks and queue those for 3.5.  But given they are no risk
  to anyone outside of xtensa, I figured to just leave them in.

  If you are OK with taking the xtensa fixes, then please pull to get:

   - one last implicit include uncovered by system.h that is in a file
     specific to just one powerpc defconfig.  (I'd sync'd with BenH).

   - fix an oversight in the PCI makefile where shared code wasn't being
     compiled for ARCH=frv

   - fix a missing include for GPIO in blackfin framebuffer.

   - audit and tag endif in blackfin ezkit board file, in order to find
     and fix the misplaced endif masking a block of code.

   - fix irq/debug.h choice of temporary macro names to be more internal
     so they don't conflict with names used by xtensa.

   - fix a reference to an undeclared local var in xtensa's signal.c

   - fix an implicit bug.h usage in xtensa's asm/io.h uncovered by my
     removing bug.h from kernel.h

   - fix xtensa to properly indicate it is using asm-generic/hardirq.h
     in order to resolve the link error - undefined ack_bad_irq

  The xtensa still fails final link as my latest binutils does something
  evil when ld forward-relocates unlikely() blocks, but in theory people
  who have older/valid toolchains could now use the thing."
