Hi all,

This is a v2 of the patch series previously posted here:

  https://lore.kernel.org/r/20210527125134.2116404-1-qperret@google.com/

Please refer to the cover letter of v1 for the context and motivation
behind the series.

Changes since v1:
 - Added comment/doc in page_alloc.c explaining the locking expectations;
 - Removed unnecessary casts in the 'page-to-list-node' helpers;
 - A few other cosmetic changes in the allocator.

Thanks,
Quentin
