* ppc-linux-nat.c (fetch_ppc_registers, store_ppc_registers): 

Don't assume that the gprs, fprs, and UISA sprs are
contiguous, start at register number zero, and end with fpscr.
Instead, use the numbers from the tdep structure.

* config/rs6000/tm-rs6000.h (FP0_REGNUM): Document that this
should no longer be used in code specific to the RS6000 and its
derivatives.
