[PATCH v3 0/2] mm: Don't set and reset page count in MEMINIT_EARLY

[Yajun Deng <yajun.deng@linux.dev>]

__init_single_page would set page count and __free_pages_core would
reset it. A lot of pages don't need to do this when in MEMINIT_EARLY
context. It's unnecessary and time-consuming.

The 1st patch is pass page count and reserved to __init_single_page.
It's in preparation for the 2nd patch, it didn't change anything.

The 2nd patch only set page count for the reserved region, not all
of the region.

  mm: pass page count and reserved to __init_single_page
  mm: Init page count in reserve_bootmem_region when MEMINIT_EARLY
