ARM: bugs: hook processor bug checking into SMP and suspend paths
BugLink: https://bugs.launchpad.net/bugs/1836426
Commit
26602161b5ba795928a5a719fe1d5d9f2ab5c3ef upstream.
Check for CPU bugs when secondary processors are being brought online,
and also when CPUs are resuming from a low power mode. This gives an
opportunity to check that processor specific bug workarounds are
correctly enabled for all paths that a CPU re-enters the kernel.
