[PATCH 0/2] x86/entry: speed up context-tracking system calls by 150 clock cycles

[Paolo Bonzini]

Two simple optimizations to the system call entry/exit code.
The first matches what commit d0e536d8939 ("context_tracking:
avoid irq_save/irq_restore on guest entry and exit", 2015-10-28)
did for guest entry and exit.  The second is just adding an
inline annotation.

Thanks,

Paolo
