Hi,
Here's another patch to sync up code between powrpc and generic mpa.c,
this time the change being in the generic code. Using long throughout
like powerpc does is beneficial since it reduces the need to switch to
32-bit instructions. It gives a very minor performance improvement
(~0.4%). OK to commit?
Have you done any measurements on 32-bit architectures? What's the result?
It has worked fine on powerpc32. x86 does not use mpa, so there's no
way to test on it. I don't have access to any other 32-bit hardware,
but this should not hurt anything that is ILP32 since long will be
32-bit anyway.
Ok, then go ahead,
Andreas
