David Mosberger-Tang 060561ff79 [IA64] In syscall-entry, use st8 instead of stf8 to clear pt_regs.r8
Using stf8 seemed like a clever idea at the time, but stf8 forces
the cache-line to be invalidated in the L1D (if it happens to be
there already).  This patch eliminates a guaranteed L1D cache-miss
and, by itself, is good for a 1-2 cycle improvement for heavy-weight
syscalls.
