Sultan fixed an issue that has been haunting us for a while on ThunderX.
It is also the root cause for some boot hangs that caused us to revert
a couple pathes last cycle, but which turned out not to actually be the
problem. Add Sultan's fix & reapply the reverted patches.

Tested on 2 CRB2S systems and 3 CRB1S systems - just to be sure :)

Marc Zyngier (2):
  arm64: Get rid of __smccc_workaround_1_hvc_*
  arm64: Use firmware to detect CPUs that are not affected by Spectre-v2

Sultan Alsawaf (1):
  UBUNTU: SAUCE: irqchip/gic-v3-its: Add missing return value in
