Commit Message

We can see that DEBUG_KMEMLEAK depends on HAVE_DEBUG_KMEMLEAK after
commit b69ec42b1b19 ("Kconfig: clean up the long arch list for the
DEBUG_KMEMLEAK config option"), just select HAVE_DEBUG_KMEMLEAK to
support kmemleak on LoongArch.

Thank you, I have already prepared a patch to update the docs,
but some more features will be added on LoongArch in the following
merge window, I am not sure what is the proper time to send the
following patch, maybe two months later, or right away, maybe
Jonathan can give some suggestions.
Documentation/features: Refresh LoongArch support files
Run the refresh script [1] to document the recent feature additions
on LoongArch.
[1] Documentation/features/scripts/features-refresh.sh
Thanks,
Tiezhu
Queued, thanks.
