ibft, x86: Change reserve_ibft_region() to find_ibft_region()
This allows arch code could decide the way to reserve the ibft. And we should reserve ibft as early as possible, instead of BOOTMEM stage, in case the table is in RAM range and is not reserved by BIOS (this will often be the case.) Move to just after find_smp_config(). Also when CONFIG_NO_BOOTMEM=y, We will not have reserve_bootmem() anymore. -v2: fix typo about ibft pointed by Konrad Rzeszutek Wilk <konrad@darnok.org> Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4BB510FB.80601@kernel.org> Cc: Pekka Enberg <penberg@cs.helsinki.fi> Cc: Peter Jones <pjones@redhat.com> Cc: Konrad Rzeszutek Wilk <konrad@kernel.org> CC: Jan Beulich <jbeulich@novell.com> Signed-off-by: H.
