[PATCH 2.6.12-mm2] perfctr: syscall numbering fixups

From: Mikael Pettersson
Date: Wed Jun 29 2005 - 16:53:27 EST


The inclusion of the pselect6 and ppoll syscalls in 2.6.12-mm2
broke ia32 emulation on x86_64, and ppc32 emulation on ppc64,
for the perfctr syscalls. This patch fixes this, and also corrects
a few comments in the ppc32 syscall tables.
