[SRU trusty] [PATCH 0/1] LP: #1750786 -- stress-ng enosys stressor

[Andy Whitcroft]

While testing some upcoming changes for trusty we found that the (newly
minted) stress-ng enosys stressor triggered a reproducible panic calling
invalid system calls.  This is triggered by a false identification of
kernel faults during uaccess operations.

Following this email is a patch for trusty which fixes the detection of
uaccess faults.

Proposing for SRU to trusty.  In theory xenial also has this same code
but the bug is not reproducible there.  Other series are not affected
by this bug as the code was replaced by a different upstream fix which
avoids the issue.
