[PATCH 0/3] x86: adjust entry frame generation
This set of patches converts the way frames gets created from
using PUSHes/POPs to using MOVes, thus allowing (in certain
cases) to avoid saving/restoring part of the register set.
While the place where the (small) win from this comes from varies
between CPUs, the net effect is a 1 to 2% reduction on a
combined interruption entry and exit when the full state save
can be avoided.
