[ Upstream commit d7f55471db2719629f773c2d6b5742a69595bfd3 ]

Fix modpost Section mismatch error in memblock_phys_alloc()

[...]
WARNING: modpost: vmlinux.o(.text.unlikely+0x1dcc): Section mismatch in reference
from the function memblock_phys_alloc() to the function .init.text:memblock_phys_alloc_range()
The function memblock_phys_alloc() references
the function __init memblock_phys_alloc_range().
This is often because memblock_phys_alloc lacks a __init
annotation or the annotation of memblock_phys_alloc_range is wrong.

ERROR: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
[...]

memblock_phys_alloc() is a one-line wrapper, make it __always_inline to
avoid these section mismatches.
