# The upstream source tree appears to be based on a fresh v6.6.36 checkin and
# then a few huge commits on top of that. A proper branch was pushed to
# spacemit-6.6.y branch on https://github.com/ncopa/linux.git
#
# Finally 6.6.52 was merged into that branch and conflicts resolved, and
# branched as spacemit-6.6.52-alpine and a diff uploaded to dev.a.o
