[GIT PULL] (xen) stable/for-linus-3.5-rc0-tag

Hey Linus,

Please git pull the following tag:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.5-rc0-tag

which has:
* support for 'perf' running. Perf depends on APIC ops to send IPIs, not SMP ops.
Re-using the existing SMP ops and also adding code to deal IRQ_WORKER vector makes it work.
* enhancements to the self-ballooning code
* fix to auto-balloon the initial domain to the original boot-up size (it would
return to the hypervisor around 1GB of memory that overlapped PCI and non-E820 RAM regions -
this brings it back).
* move some of the debugfs code dealing with printing u32 arrays to the generic code-base.
* allow fronted modules to unload with grants in usage and lazily free them
* further disintegrate the XenBus and initial domain coupling - so that there can be
a separate XenBus domain - and the concept of initial domain shrinks even further.
* perf improvements in the M2P calls to utilize the batching of PTEs.
* bug-fixes

Please pull!
