Hi,
I'm seeing bare metal ppc64le system crashing early during boot
with latest upstream kernel (4.4.0-rc8):

Hi,
LTP mmap03 is getting stuck in page fault loop after commit
c46241a370a6 ("powerpc/pkeys: Check vma before returning key fault error to
the user")
System is ppc64le P9 lpar [1] running v5.8-rc2-34-g3e08a95294a4.
Here's a minimized reproducer:

Avoid renaming .init_array section, so do_mod_ctors() can use it.

I did CC him using email address from patch. Maybe some list
de-duplication dropped it?

Hi,
I'm running into panics with stack protector enabled on ppc64le
lpar (IBM,8408-E8E), starting with:

Hi,
I'm chasing a memory corruption with 4.8-rc7 as I'm observing random Oopses
on ppc BE/LE systems (lpars, KVM guests). About 30% of issues is that
module list gets corrupted, and "cat /proc/modules" or "lsmod" triggers
an Oops, for example:

Hi Denis / all,
Do you know if there is a patch or lead for this problem? I seem
to be hitting same Oops with P730 lpar when running 4.8 (see below),
but 4.7.7 looks OK.

Jan
