[PATCH -next v1 02/16] kvm-check-branches.sh: Remove in favor of kvm-series.sh

[Joel Fernandes <joelagnelf@nvidia.com>]

From: "Paul E. McKenney" <paulmck@kernel.org>

The kvm-series.sh script is an order-of-magnitude optimization of
kvm-check-branches.sh, so remove the old script.

-# Run a group of kvm.sh tests on the specified commits.  This currently
-# unconditionally does three-minute runs on each scenario in CFLIST,
-# taking advantage of all available CPUs and trusting the "make" utility.
-# In the short term, adjustments can be made by editing this script and
-# CFLIST.  If some adjustments appear to have ongoing value, this script
-# might grow some command-line arguments.
-#
-# Usage: kvm-check-branches.sh commit1 commit2..commit3 commit4 ...
-#
-# This script considers its arguments one at a time.  If more elaborate
-# specification of commits is needed, please use "git rev-list" to
-# produce something that this simple script can understand.  The reason
-# for retaining the simplicity is that it allows the user to more easily
-# see which commit came from which branch.
-#
-# This script creates a yyyy.mm.dd-hh.mm.ss-group entry in the "res"
-# directory.  The calls to kvm.sh create the usual entries, but this script
-# moves them under the yyyy.mm.dd-hh.mm.ss-group entry, each in its own
-# directory numbered in run order, that is, "0001", "0002", and so on.
-# For successful runs, the large build artifacts are removed.  Doing this
-# reduces the disk space required by about two orders of magnitude for
-# successful runs.
