Subject: xen/multicalls: disable MC_DEBUG
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ffc78767f2ac5b8007aeb366e748c8dd8b8bc3a3;p=linux-beck.git

It's useful - and probably should be a config - but its very heavyweight,
especially with the tracing stuff to help sort out problems.
