Hi Konrad,

x86 implements all of them by default - and we just
add two extra HAS_ variables to be declared in autoconf.h.

ARM 64 only has alternative while ARM 32 has none of them.

And while at it change the livepatch common code that
would benefit from this.

v2: First submission
v3: Move the config options to common code
    Don't include <xen/config.h> in the file.
    Don't even include <xen/kconfig.h> in the file as xen/Rules.mk automatically
    includes the config.h for every GCC invocation.
v4: Depend on "arm64: s/ALTERNATIVE/HAS_ALTERNATIVE/"

I can't find this patch on the ML. Did you forget to send it?
