      torture: Make thread detection more robust by using lspcu · 8e82c28e
      Paul Menzel authored 
      For consecutive numbers the lscpu command collapses the output and just
shows the range with start and end. The processors are numbered that
way on POWER8.

    $ sudo ppc64_cpu --smt=8
    $ lscpu | grep '^NUMA node'
    NUMA node(s):                    2
    NUMA node0 CPU(s):               0-79
    NUMA node8 CPU(s):               80-159

This causes the heuristic to detect the number threads per core, looking
for the number after the first comma, to fail, and QEMU aborts because of
invalid arguments.

    $ lscpu | grep '^NUMA node0' | sed -e 's/^[^,-]*(,|\-)\([0-9]*\),.*$/\1/'
    NUMA node0 CPU(s):               0-79

But the lscpu command shows the number of threads per core:

    $ sudo ppc64_cpu --smt=8
    $ lscpu | grep 'Thread(s) per core'
    Thread(s) per core:              8
    $ sudo ppc64_cpu --smt=off
    $ lscpu | grep 'Thread(s) per core'
    Thread(s) per core:              1

This commit therefore directly uses that value and replaces use of grep
with "sed -n" and its "p" command.

      torture: Permit running of experimental torture types · 98bb264b
      Paul E. McKenney authored 
      This commit weakens the checks of the kvm.sh script's --torture parameter
and the kvm-recheck.sh script's parsing so that experimental torture tests
may be created without updating these two scripts.  The changes required
are to the appropriate Makefile and Kconfig file, plus a directory
whose name begins with "X" must be added to the rcutorture/configs file.
This new directory's name can then be passed in via the kvm.sh script's
--torture parameter.

      torture: Use "-o Batchmode=yes" to disable ssh password requests · b20842ba
      Paul E. McKenney authored 
      The torture.sh script normally runs unattended, so there is not much
point in the "ssh" command asking for a password.  This commit therefore
adds the "-o Batchmode=yes" argument to each "ssh" command to cause it
to fail rather than ask for a password.

      torture: Reposition so that $? collects ssh code in torture.sh · ab3ecd0b
      Paul E. McKenney authored 
      An "echo" slipped in between an "ssh" and the "ret=$?" that was intended
to collect its exit code, which prevents torture.sh from detecting
"ssh" failure.  This commit therefore reassociates the two.
