Merge tag 'sti-soc-for-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti into next/soc
Merge "STi SoC changes for v4.8" from Patrice Chotard:
- Add a dummy L2 cache's write_sec callback as in non secure mode execution,
we can't get access to L2 cache secure registers
- Cosmetics change, in case of dump_stack, update the hardware name with a
more generic for the STi SoCs family
* tag 'sti-soc-for-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti:
ARM: sti: Implement dummy L2 cache's write_sec
ARM: STi: Update machine _namestr to be more generic.
