Subject: [PATCH tip/core/rcu 24/32] tools/memory-model: Fix scripting --jobs argument

From: "Paul E. McKenney" <paulmck@...ux.ibm.com>

The parseargs.sh regular expression for the --jobs argument incorrectly
requires that the number of jobs be at least 10, that is, have at least
two digits.  This commit therefore adjusts this regular expression to
allow single-digit numbers of jobs to be specified.
