[PATCH 0/2] A couple of qspinlock fixes

[Will Deacon]

Hi all,

Here are a couple of fixes for qspinlock issues I've found by code
inspection whilst investigating the possibility of enabling this for
arm64. The first patch fixes a problem with unusual hardware re-ordering
whilst the second fixes a problem with unusual compiler re-ordering.

Cheers,

Will
