free_memmap is an inline function, but gcc may choose to ignore that
when CONFIG_OPTIMIZE_INLINING is set. In that case it is put in the
.text section, causing a kbuild warning:

WARNING: vmlinux.o(.text.unlikely+0x1a0): Section mismatch in reference from the function free_memmap() to the function .init.text:__memblock_free_early()
The function free_memmap() references
the function __init __memblock_free_early().
This is often because free_memmap lacks a __init
annotation or the annotation of __memblock_free_early is wrong.

FATAL: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.

This marks the function both inline and __init, which is a
correct annotation and avoids the problem.
