Series powerpc/ps3: Fixes for lv1 hcall assembly | expand

Commit Message

Nicholas Piggin Dec. 27, 2023, 7:24 a.m. UTC 
The LRSAVE constant is required for assembly compiled for both 32-bit
and 64-bit, because the value differs there. PS3 is 64-bit only so
this is a noop, but it is nice to abstract stack frame offsets.
