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] 20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) | ^~ ./include/linux/minmax.h:26:18: note: in expansion of macro ‘__typecheck’ 26 | (__typecheck(x, y) && __no_side_effects(x, y)) | ^~~~~~~~~~~ ./include/linux/minmax.h:36:31: note: in expansion of macro ‘__safe_cmp’ 36 | __builtin_choose_expr(__safe_cmp(x, y), \ | ^~~~~~~~~~ ./include/linux/minmax.h:45:25: note: in expansion of macro ‘__careful_cmp’ 45 | #define min(x, y) __careful_cmp(x, y, <) | ^~~~~~~~~~~~~ arch/x86/xen/enlighten_pvh.c:117:25: note: in expansion of macro ‘min’ 117 | pages = min(extra_pages, | ^~~ cc1: all warnings being treated as errors So I'm dropping it for now. thanks, greg k-h
