x86_64: add pseudo-features for 32-bit compat syscall
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: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
