Pull ARM SoC fixes from Olof Johansson:
 "Much smaller batch of fixes this week.

  Biggest one is a revert of an OMAP display change that removed some
  non-DT pinmux code that was still needed for 3.13 to get DSI displays
  to work.

  There's also a fix that resolves some misdescribed GPIO controller
  resources on shmobile.  The rest are mostly smaller fixes, a couple of
  MAINTAINERS updates, etc"

From Simon Horman:
Renesas ARM based SoC fixes for v3.13

* r8a7790 (R-Car H1) SoC
  - Correct GPIO resources in DT.

    This problem has been present since GPIOs were added to the r8a7790 SoC
    by f98e10c88aa95bf7 ("ARM: shmobile: r8a7790: Add GPIO controller
    devices to device tree") in v3.12-rc1.

* irqchip renesas-intc-irqpin
  - Correct register bitfield shift calculation

    This bug has been present since the renesas-intc-irqpin driver was
    introduced by 443580486e3b9657 ("irqchip: Renesas INTC External IRQ pin
    driver") in v3.10-rc1

* Lager board
  - Do not build the phy fixup unless CONFIG_PHYLIB is enabled

    This problem was introduced by 48c8b96f21817aad

Patch queue for 3.13 - 2013-12-18

This fixes some grave issues we've only found after 3.13-rc1:

  - Make the modularized HV/PR book3s kvm work well as modules
  - Fix some race conditions
  - Fix compilation with certain compilers (booke)
  - Fix THP for book3s_hv
  - Fix preemption for book3s_pr

Pull Xen bugfixes from Konrad Rzeszutek Wilk:
 - Fix balloon driver for auto-translate guests (PVHVM, ARM) to not use
   scratch pages.
 - Fix block API header for ARM32 and ARM64 to have proper layout
 - On ARM when mapping guests, stick on PTE_SPECIAL
 - When using SWIOTLB under ARM, don't call swiotlb functions twice
 - When unmapping guests memory and if we fail, don't return pages which
   failed to be unmapped.
 - Grant driver was using the wrong address on ARM.

  xen: privcmd: do not return pages which we have failed to unmap
  XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn

I accidentally removed some mux code for omap4 that I thought was
dead code as omap4 has been booting with device tree only since
v3.10. Turns out I also removed some display related mux code,
so let's revert that except for the dead code parts.

  Revert "ARM: OMAP2+: Remove legacy mux code for display.c"
  +Linux 3.13-rc4

Commit 8f34a1da35ae ("arm64: ptrace: use HW_BREAKPOINT_EMPTY type for
disabled breakpoints") fixed an issue with GDB trying to zero breakpoint
control registers. The problem there is that the arch hw_breakpoint code
will attempt to create a (disabled), execute breakpoint of length 0.

This will fail validation and report unexpected failure to GDB. To avoid
this, we treated disabled breakpoints as HW_BREAKPOINT_EMPTY, but that
seems to have broken with recent kernels, causing watchpoints to be
treated as TYPE_INST in the core code and returning ENOSPC for any
further breakpoints.

This patch fixes the problem by prioritising the `enable' field of the
breakpoint: if it is cleared, we simply update the perf_event_attr to
indicate that the thing is disabled and don't bother changing either the
type or the length. This reinforces the behaviour that the breakpoint
control register is essentially read-only apart from the enable bit
when disabling a breakpoint.

Commit 97bc386fc12d "ARC: Add guard macro to uapi/asm/unistd.h"
inhibited multiple inclusion of ARCH unistd.h. This however hosed the system
since Generic syscall table generator relies on it being included twice,
and in lack-of an empty table was emitted by C preprocessor.

Fix that by allowing one exception to rule for the special case (just
like Xtensa)
