Subject[patch V2 0/7] x86/kvm: RCU/context tracking and instrumentation protections
Folks,

this is a rebased and adopted version of the original series which is
available here:

https://lore.kernel.org/r/20200519203128.773151484@linutronix.de

It deals with the RCU and context tracking state and the protection against
instrumentation in sensitive places:

- Placing the guest_enter/exit() calls at the correct place

- Moving the sensitive VMENTER/EXIT code into the non-instrumentable code
section.

- Fixup the tracing code to comply with the non-instrumentation rules

- Use native functions to access CR2 and the GS base MSR in the critical
code pathes to prevent them from being instrumented.

Thanks,

tglx
