Thinking about this more, we can shave off the first 4 chars and have it
be:
spec_mitigations=
I think it is painfully clear which speculation mitigations we mean. And
the other switches don't have "cpu_" prefixes too so...

Starting with v5 of NXP QBMan devices the hardware supports using
regular cacheable/shareable memory as the backing store for the
portals.
This patch adds support for the new portal mode by switching to
use the DPRC get object region v2 command which returns both
a base address and offset for the
NXP devices with QBMan version 5 and above can enable software
portals that are memory backed. This allows the portal to be
mapped as cacheable/sharable (same as all normal memory) so
that portals can freely migrate between cores and clusters
in the SoC. The driver will enable this mode by default
This patch series adds support for QBMan memory backed portals which is
avaialble in devices containing QBMan verion 5.0 and above (for example
NXP's LX2160A SoC).
Memory backed portals can be mapped as normal cacheable/shareable memory
which allows the portals to migrate between cores without

This patch sets up flags for the state which needs to be auto-promoted. On
POWERNV system, only lite states need to be autopromoted. We identify lite
states by those which do not lose user context. That information has been
used to set the flag for lite states.
