[PATCH 0/6][lunar linux-azure] Azure: CPU lockup in CVM instances

[Tim Gardner]

BugLink: https://bugs.launchpad.net/bugs/2026736

SRU Justification

[Impact]

Azure CVM instances can lock up when run under stress.

[Test Plan]

MSFT tested using the nttcp test. Reproducing the lockup often
requires several hours. MSFT has tested with this patch set for
at least one pass thus far.

[Regression potential]

CVM instances could continue to lock up under stress.
