Add pseudo-feature bits to describe whether the CPU supports sysenter and/or syscall from ia32-compat userspace. This removes a hardcoded test in vdso32-setup. Signed-off-by: NJeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

(They are buggy because they don't have memory barriers to prevent them from being reordered with respect to memory accesses.)
