this hack can go away once we have a proper percpu_alloc() that can be
used early enough.

where is that fancy patch? current percpu_alloc(), will keep big
pointer in array..., instead of put that pointer in percpu_area

64bit has that after_bootmem already.

or at least introduce a "bootmem agnostic" allocator instead of
open-coding the after_bootmem flag.

Something like:

early_kzalloc()

?

Andrew, any preferences?

My mind reading ain't what it was, and this after_bootmem flag is
write-only in this patch.

So what's all this about?
