This patchset depends on this patchset[1] and this patch[2] which adds support
for polarity control in imx-pwm driver.
- Use pwm polarity control on iMX7 based modules.
- Enable polarity control on Toradex Colibri iMX7D/S module.
- Add BL_ON GPIO control for Toradex Colibri iMX7D/S module.

So far there is no comment which would require any modification in
this patch set. However, a rebase would be required, because we have a
fixup "arm64: Improve kprobes test for atomic sequence" in the next

register_shrinker can fail after commit 1d3d4437eae1 ("vmscan: per-node
deferred work"), we should detect the failure of it, otherwise we may
fail to register shrinker after raid5 configuration was setup successfully.

We start with a delete of a duplicate prototype in asm/exception.h

Most of the other C content in asm files is implemented in macro form.
