mm/sparse: move mem_section init to sparse_extreme_init()
Patch series "mm/sparse: remove SECTION_MARKED_PRESENT and further
cleanups", v2.
SECTION_MARKED_PRESENT is really only needed during boot, where we can
instead just rely on SECTION_IS_EARLY_BIT by setting that flag earlier.
Some preparations for doing that conversion and some cleanups in the same
(sparse) area.
This patch (of 13):
Let's just avoid another pair of ifdef inside a function. While at it,
switch to INTERNODE_CACHE_BYTES by just defining a fallback in cache.h as
well, given that the x86 variant already provides one.
