Subject: kbuild: support mercurial in setlocalversion
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3dce174cfcba11026b028d33bed0438b80e37124;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

kbuild: support mercurial in setlocalversion

This represents mercurial changesets similarly to git.  For untagged
revisions, append the changeset id.  If there are uncommitted changes,
append -dirty.  For example, -hgc60016ba6237-dirty
