Merge remote-tracking branch 'bonzini/tags/for-anthony' into staging

Here are a bunch of 1.7-tagged patches that I was afraid
were getting forgotten or that did not have a clear maintainer responsible
for making a pull request.

# gpg: Signature made Thu 21 Nov 2013 08:40:59 AM PST using RSA key ID 9B4D86F2

* bonzini/tags/for-anthony:
  qga: Fix compiler warnings (missing format attribute, wrong format strings)
  mips jazz: do not raise data bus exception when accessing invalid addresses
  target-i386: yield to another VCPU on PAUSE
  rng-egd: offset the point when repeatedly read from the buffer
  rng-egd: remove redundant free
  target-i386: Fix build by providing stub kvm_arch_get_supported_cpuid()
  vfio-pci: Fix multifunction=on
  atomic.h: Fix build with clang
  pc: get rid of builtin pvpanic for "-M pc-1.5"
  configure: Explicitly set ARFLAGS so we can build with GNU Make 4.0
  sun4m: Add FCode ROM for TCX framebuffer
