From: Grygorii Strashko <grygorii_strashko@xxxxxxxx>
Constify is_32/64bit_domain() macro for the case CONFIG_ARM64_AARCH32=n and
so allow compiler to opt out Aarch32 specific code.
(CONFIG_ARM64_AARCH32=y)
Before:
text data bss dec hex filename
855232 322404 270880 1448516 161a44 xen-syms
(CONFIG_ARM64_AARCH32=n, CONFIG_EXPERT=y)
After:
text data bss dec hex filename
851568 322404 270880 1444852 160bf4 xen-syms
