The first patches are the two optimizations I posted on May 30th
for the system call entry/exit code. The only change is in the
function names, which use the user_{enter,exit}_irqoff favored
by Andy and Ingo. The first patch 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 simply adds
an inline annotation; the compiler doesn't figure it out because the
function is not static.
The second two patches move guest_{enter,exit} to the same naming
convention, removing the KVM wrappers kvm_guest_{enter,exit} and
__kvm_guest_{enter,exit} in the process. I would like these two to
go through the KVM tree because I have other optimizations for 4.8
on top of these patches.
Thanks,
Paolo
