Merge branch 'core/documentation' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into docs-next
A week late but I managed to complete it all and moved it into Git, for better
structure and easy pulling.
Changes relative to the last submission:
- Added higher level subsystem directories to collect features by
subsystem:
triton:~/tip> ls Documentation/features/
arch-support.txt core debug io lib list-arch.sh locking perf sched seccomp time vm
each subsystem directory contains the feature directories. For example locking
has:
triton:~/tip> ls Documentation/features/locking/
cmpxchg-local lockdep queued-rwlocks queued-spinlocks rwsem-optimized
It's all pretty straightforward to navigate. Advantages are better
visualization, plus git log is able to list changes per subsystem.
- Prettified the visualization some more.
- Improved/corrected the support matrices based on feedback to earlier submissions.
- Updated the support matrices to today's linux-next, so that by the time this
shows up in upstream in the next merge window it's really recent.
Most notably there's a new architecture in linux-next (h8300).
This structure should address all feedback that I got and should minimize the
maintenance overhead (chance of conflicts).
