mm: reduce deferred struct page init ifdeffery
Patch series "mm: Fix several issues with unaccepted memory", v2.
The patchset addresses several issues related to unaccepted memory.
Pacth 1/7 preparatory cleanup.
Patch 2/7 ensures that __alloc_pages_bulk() will not exhaust all
accepted memory without accepting more.
Patches 3/7-5/7 are preparations for patch 6/7, which fixes
alloc_config_page() on machines with unaccepted memory. This allows, for
example, the allocation of gigantic pages at runtime.
Patch 7/7 enables the kernel to accept memory up to the promo watermark.
This patch (of 7):
Add dummy _deferred_grow_zone() for !DEFERRED_STRUCT_PAGE_INIT and remove
#ifdefs in two places.
No functional changes.
