Re: [PATCH 0/8] Convert powerpc to default topdown mmap layout

Excerpts from Christophe Leroy's message of November 22, 2021 6:48 pm:

This series converts powerpc to default topdown mmap layout.

powerpc provides its own arch_get_unmapped_area() only when
slices are needed, which is only for book3s/64. First part of
the series moves slices into book3s/64 specific directories
and cleans up other subarchitectures.

Then a small modification is done to core mm to allow
powerpc to still provide its own arch_randomize_brk()

Last part converts to default topdown mmap layout.

A nice series but will clash badly with the CONFIG_HASH_MMU 
series of course. One will have to be rebased if they are
both to be merged.

Thanks,
Nick
