With commit aa888a74977a8 ("hugetlb: support larger than MAX_ORDER") we added
support for allocating gigantic hugepages via kernel command line. Switch
ppc64 arch specific code to use that.
Is it only ppc64 ? Your patch removes things defined for the 8xx and
modifies stuff in init_32.c
On the 8xx, as far as I remember, 8M pages on 4k pages mode are above
default MAX_ORDER, I solved it by increasing MAX_ORDER. Is that wrong ?
I was hoping every platform can switch to generic code. Obviously I
didn't test the changes on anything other than ppc64. Can you try with
this patchset and pass hugepagesz=<size> hugepages=<number> kernel arg
and see if hugepage allocation works for you ?
I'm sorry I didn't have time to test it this week and I won't have time
either in the next two weeks.
