4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dave Young <dyo...@redhat.com> [ Upstream commit 835bcec5fdf3f9e880111b482177e7e70e3596da ] 'add_efi_memmap' is an early param, but do_add_efi_memmap() has no chance to run because the code path is before parse_early_param(). I believe it worked when the param was introduced but probably later some other changes caused the wrong order and nobody noticed it. Move efi_memblock_x86_reserve_range() after parse_early_param() to fix it.
