This sorts the actual field names too, potentially causing even more
chaos and confusion at merge time if you have edited the MAINTAINERS
file. But the end result is a more consistent layout, and hopefully
it's a one-time pain minimized by doing this just before the -rc1
release.
This was entirely scripted:
./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order

They are all supposed to be sorted, but people who add new entries don't
always know the alphabet. Plus sometimes the entry names get edited,
and people don't then re-order the entry.
Let's see how painful this will be for merging purposes (the MAINTAINERS
file is often edited in various different trees), but Joe claims there's
relatively few patches in -next that touch this, and doing it just
before -rc1 is likely the best time. Fingers crossed.
This was scripted with
/scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
but then I also ended up manually upper-casing a few entry names that
stood out when looking at the end result.

detection feature.
It addressed the case where a KVM guest triggers a split lock #AC and KVM
reinjects it into the guest which is not prepared to handle it.
Adds proper sanity checks which prevent the unconditional injection into
the guest and handles the #AC on the host side in the same way as user
space detections are handled. Depending on the detection mode it either
warns and disables detection for the task or kills the task if the mode is
set to fatal.
