The main purpose is to blacklist the Intel Resource Director Technology MSRs.
We do not yet virtualise support for guests, but Linux has been observed to
probe for these MSRs without checking CPUID first.
The architecturally inaccessable ranges don't need to fall back into the
legacy ranges, becau
Hitting the fail path with err = 0 causes callers to dereference a NULL
pointer, as 0 fails an IS_ERR() check.
All of the paths appear to be fine, but leave some logic to help catch stray
misuses.

L.S.,
When starting a guest with the 'xl create' command (non-verbose) i get
this extra output on PVH guest types only:
S3 disabled
S4 disabled
CONV disabled
It seems libacpi/* only contains normal printf's, so for the other guest
types i probably just never triggered one of them.

Hi!
We found this tiny bug when we were unplugging and re-plugging
different block-devices to a guest and found a bug in there
resulting in the multi-queue parameter being lost.
This patch fixes it. I meant to post this in December but
got side-tracked with Spectre_v2 work.

negotiate_mq should happen in all cases of a new VBD being discovered by
xen-blkfront, whether called through _probe() or a hot-attached new VBD
from dom-0 via xenstore. Otherwise, hot-attached new VBDs are left
configured without multi-queue.
