Subject: patman: Cache the CC list from MakeCcFile() for use in ShowActions()
X-Git-Tag: v2013.04-rc1~62^2~6
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d94566a1115d35f87db793d2daaa79823528937c;p=oweals%2Fu-boot.git

patman: Cache the CC list from MakeCcFile() for use in ShowActions()

Currently we go through and generate the CC list for patches twice.
This gets slow when (in a future CL) we add a call to
get_maintainer.pl on Linux.  Instead of doing things twice, just cache
the CC list when it is first generated.
