[PATCH] powerpc: PPCA2/A2 optimized memcpy function

Subject: [PATCH] powerpc: PPCA2/A2 optimized memcpy function

Greetings,

What follows are a 32 bit and 64 bit optimized version for memcpy.S for the POWER family 'PPCA2' processor core. They are regression tested for 32/64 bit. PPCA2 is a member of the POWER server class CPUs, and it uses no new or implementation specific instructions - the code is just optimized for this particular pipeline.

This particular version of the patch correctly deals with what the kernel thinks the name of the architecture is (ppca2) vs. what the sysdeps directories are (a2).


Regards,
Michael Brutman
