Ok Scott,
now it works!
We had severals hardware problem.
Thanks for your help

Please add them to the CODEC binding instead.

Hi,
This patch series add support for numa faults on ppc64 architecture. We steal
the
_PAGE_COHERENCE bit and use that for indicating _PAGE_NUMA. We clear the
_PAGE_PRESENT bit
and also invalidate the hpte entry on setting _PAGE_NUMA. The next fault on that
page will be considered a numa fault.
From: "Aneesh Kumar K.V"
We want to make sure we don't use these function when updating a pte
or pmd entry that have a valid hpte entry, because these functions
don't invalidate them. So limit the check to _PAGE_PRESENT bit.
Numafault core changes use these functions for updating _PAGE_NUMA bits.
From: "Aneesh Kumar K.V"
Even though we have same value for linux PTE bits and hash PTE pits
use the hash pte bits wen updating hash pte

change_prot_numa should work even if _PAGE_NUMA != _PAGE_PROTNONE.
On archs like ppc64 that don't use _PAGE_PROTNONE and also have
a separate page table outside linux pagetable, we just need to
make sure that when calling change_prot_numa we flush the
hardware page table

Archs like ppc64 have different layout for pmd entries pointing to PTE
page. Hence add a separate function for modifying them

After commit e2b3d202d1dba8f3546ed28224ce485bc50010be we have the
below possible formats for pmd entry
(1) invalid (all zeroes)
(2) pointer to next table, as normal; bottom 6 bits == 0
(3) leaf pte for huge page, bottom two bits != 00
(4) hugepd pointer, bottom two bits
From: "Aneesh Kumar K.V"
We steal the _PAGE_COHERENCE bit and use that for indicating NUMA ptes.
This patch still disables the numa hinting using pmd entries. That
require further changes to pmd entry format which is done in later
patches.

Set memory coherence always on hash64 config. If
a platform cannot have memory coherence always set they
can infer that from _PAGE_NO_CACHE and _PAGE_WRITETHRU
like in lpar. So we dont' really need a separate bit
for tracking _PAGE_COHERENCE.

Frederic,
In the perf ring buffer code we have this in perf_output_get_handle():
if (!local_dec_and_test(&rb->nest))
goto out;
/*
