Subject: [PATCH 08/28] stress-ng: add checksum sanity check on bogo ops stats
and run flag
ELISA request for run sanity check involves adding a duplicated bogo
ops and run flag in a different shared memory segment, hashing this
data and checking these with the stats at the end of a run. If any
corruption or run failures occur we have a mechanism of ensuring that
the measurements are sane with a hashed check on the data and comparing
the two separate copies.

Subject: [PATCH 10/28] core-shim: rework waitpid again, terminate child on
EINTR (LP: #1879447)
The parent may receive a EINTR on a SIGALRM so send this to the
child. If it hasn't died after a while send the child SIGKILL
to force termination.

Subject: [PATCH 11/28] Add memory barriers an ready flag to check if counter
is in a sane state
The counter now is protected with a ready flag that is set to false
during the counter update. The ordering of the flag unset, counter
update and flag set is protected with memory barriers to enforce
strict ordering. Add a check at the end of the run to check if
the counter ready flag is in a sane state and fail with an error
if it is set incorrectly. Addresses concerns raised by ELISA.

Fix this so that we only sanity check full runs of data.

Subject: [PATCH 20/28] Fix --seq mode checksum with multiple stressors and
sanity checking
The sanity checking of bogo ops is using the same base offset of
the checksum pointer for each round of stressor being run. Fix this
by ensuring it is incremented per run so that the sanity checking
checksumming and bogo op counter is stashed in the correct slot.
