* Performance improvement to lower the amount of traps the hypervisor
has to do 32-bit guests. Mainly for setting PTE entries and updating
TLS descriptors.
* MCE polling driver to collect hypervisor MCE buffer and present them to
/dev/mcelog.
* Physical CPU online/offline support. When an privileged guest is booted
it is present with virtual CPUs, which might have an 1:1 to physical
CPUs but usually don't. This provides mechanism to offline/online physical
CPUs.
Bug-fixes for:
* Coverity found fixes in the console and ACPI processor driver.
* PVonHVM kexec fixes along with some cleanups.
* Pages that fall within E820 gaps and non-RAM regions (and had been
released to hypervisor) would be populated back, but potentially in
non-RAM regions.
