Andy Lutomirski 6dcc94149d x86/entry: Only allocate space for tss_struct::SYSENTER_stack if needed ... The SYSENTER stack is only used on 32-bit kernels. Remove it on 64-bit kernels. ( We may end up using it down the road on 64-bit kernels. If so, we'll re-enable it for CONFIG_IA32_EMULATION. ) Signed-off-by: Andy Lutomirski <luto@kernel.org> Cc: Andrew Cooper <andrew.cooper3@citrix.com> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.
