History
Linus Torvalds 3370b69eb0 Four changes: 
- x86: work around two nasty cases where a benign exception occurs while
 another is being delivered.  The endless stream of exceptions causes an
 infinite loop in the processor, which not even NMIs or SMIs can interrupt;
 in the virt case, there is no possibility to exit to the host either.
 
 - x86: support for Skylake per-guest TSC rate.  Long supported by AMD,
 the patches mostly move things from there to common arch/x86/kvm/ code.
 
 - generic: remove local_irq_save/restore from the guest entry and exit
 paths when context tracking is enabled.  The patches are a few months
 old, but we discussed them again at kernel summit.  Andy will pick up
 from here and, in 4.5, try to remove it from the user entry/exit paths.
 
 - PPC: Two bug fixes, see merge commit 370289756b for details.
