This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
https://ozlabs.org/~akpm/mmotm/series
on i386:

Hum ...
Comes from my patch
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/5ac5976419350e8e048d463a64cae449eb3ba4b0.1620795204.git.christophe.leroy@xxxxxxxxxx/
But, that happens only if x86 defines __PAGETABLE_PUD_FOLDED. And if PUD is folded, then I can't
understand my it has pud_set_huge() and pud_clear_huge() functions.
