Hi all,
Today's linux-next merge of the powerpc tree got a conflict in:
Documentation/admin-guide/kernel-parameters.txt
between commits:
05736e4ac13c ("cpu/hotplug: Provide knobs to control SMT")
506a66f37489 ("Revert "x86/apic: Ignore secondary threads if nosmt=force"")
from Linus' tree

pgtable_cache_add() gracefully handles the case when a cache that
size already exists by returning early with the following test:
if (PGT_CACHE(shift))
return; /* Already have a cache of this size */
It is then not needed to test the existence of the cache before.

Instead of opencoding cache handling for the special case
of hugepage tables having a single pte_t element, this
patch makes use of the common pgtable_cache helpers

hugepages uses a cache of order 0. Lets allow page tables
of order 0 in the common part in order to avoid open coding

This code is copied from binutils and we do
When two processes crash at the same time, we sometimes encounter
nesting in the middle of a line:
[4.365317] init[1]: segfault (11) at 0 nip 0 lr 0 code 1
[4.370452] init[1]: code:
[4.372042] init[74]: segfault (11) at 10a74 nip 1000c198 lr 100078c8
instructions_to_print var is assigned value 16 and there is no
way to change it.
This patch replaces it by a constant.
