[GIT PULL] (xen) stable/for-linus-3.6-rc0-tag

[Konrad Rzeszutek Wilk]

Hey Linus,

Please git pull the following tag:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.6-rc0-tag

which has three nice features and various bug-fixes. A nice summary of them is included
in the git tag. A shorter summary is that two of them are patches mainly for
enterprise machines - to collect MCE data and also offline/online CPUs. Then there is
performance improvements to minimize the amount of traps done to the hypervisor.
And then there are some little fixes. The biggest one is to make PVonHVM guest able
to successfully do an kexec 100% instead of "most" of the time - there were certain
pages that ended up being stamped by the hypervisor after the new kernel was booted -
the patches fix that.

Here is the diff stat.
