This breaks the build on 6.1.y kernels:
In file included from ./include/linux/ioport.h:15,
from ./include/linux/acpi.h:12,
from arch/x86/xen/enlighten_pvh.c:2:
arch/x86/xen/enlighten_pvh.c: In function ‘xen_reserve_extra_memory’:
./include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]

cc1: all warnings being treated as errors
So I'm dropping it for now.
thanks,
