The following commit has been merged into the core/rcu branch of tip: Commit-ID: f8c8484dbda78e09912a391a8c87414920bbdfee Gitweb: https://git.kernel.org/tip/f8c8484dbda78e09912a391a8c87414920bbdfee Author: Frederic Weisbecker <frederic@xxxxxxxxxx> AuthorDate: Thu, 01 Apr 2021 15:26:02 +02:00 Committer: Paul E. McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 10 May 2021 16:05:06 -07:00 torture: Correctly fetch number of CPUs for non-English languages Grepping for "CPU" on lscpu output isn't always successful, depending on the local language setting. As a result, the build can be aborted early with: "make: the '-j' option requires a positive integer argument" This commit therefore uses the human-language-independent approach available via the getconf command, both in kvm-build.sh and in kvm-remote.sh.
