[PATCH] x86_64: fix 32-bit thread debugging

Browse source

The IA32 ptrace emulation currently returns the wrong registers for fs/gs;
it's returning what x86_64 calls gs_base.  We need regs.gsindex in order
for GDB to correctly locate the TLS area.  Without this patch, the 32-bit
GDB testsuite bombs on a 64-bit kernel.  With it, results look about like
I'd expect, although there are still a handful of kernel-related failures
(vsyscall related?).
