OOI what is the size increase of the final (stripped) binary with this

I compared the file xen/xen and on both arm32/arm64 the binary is
smaller of about 2%.

I think this is because previously gcc wasn't merge the string when
BUG_ON was used in inline function.

BTW this series won't work correctly because of XSA-102 on ARM64 when WARN_ON/BUG_ON/ASSERT is used in startup code.
This is because the "current" is set to a debug sanity value.

Do you plan to send the series to add support for 32-bit userspace on 64-bits kernels for Xen 4.5?
