Subject: [PATCH 0/2] mm: alloc_pages_bulk: small API refactor

Hi,

Today, alloc_pages_bulk_noprof() supports two arguments to return allocated
pages: a linked list and an array. There are also higher level APIs for both.

However, the linked list API has apparently never been used. So, this series
removes it along with the list API and also refactors the remaining API naming
for consistency.

I've boot-tested this series on arm64 and built-tested it on x86.

PS: Matthew, it was easier to keep my patch instead of fixing up Mel's but I
included the API refactoring patch as well.

PPS: It's probably good to have a free_pages_bulk() function, but I'll leave
this for another day.

  mm: alloc_pages_bulk_noprof: drop page_list argument
  mm: alloc_pages_bulk: rename API
