A zone reset only fails for conventional zones. Resetting a conventional
zone indicates a bug in the software that submitted the zone reset so
the information about a zone reset failure is useful information. Hence,
do not suppress information about zone reset failures.

scsi_io_completion() translates the sense key ILLEGAL REQUEST / ASC
0x21 into ACTION_FAIL. That means that setting cmd->allowed to zero
in sd_zbc_complete() for this sense code / ASC combination is not
necessary. Hence remove the code that resets cmd->allowed from
sd_zbc_complete().

2.16.3
From: Konrad Rzeszutek Wilk <konrad.wilk(a)oracle.com>
(cherry picked from commit 36268223c1e9981d6cfc33aff8520b3bde4b8114)
As:
1) It's known that hypervisors lie about the environment anyhow (host
mismatch)
2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid
"correct" value, it all gets to be very murky when migration happens
(do you provide the "new" microcode of the machine?).
And in reality the cloud vendors are the ones that should make sure that
the microcode that is running is correct and we should just sing lalalala
and trust them.

1.9.1
From: Paolo Bonzini <pbonzini(a)redhat.com>
commit 946fbbc13dce68902f64515b610eeb2a6c3d7a64 upstream.
vmx_vcpu_run() and svm_vcpu_run() are large functions, and giving
branch hints to the compiler can actually make a substantial cycle
difference by keeping the fast path contiguous in memory.
With this optimization, the retpoline-guest/retpoline-host case is
about 50 cycles faster.

When looking up the clock we must use the client->dev as device since that
is the one which is probed via DT.

Hi,
Changes since v1:
- Removed the Fixes line and add tag only for v4.16 to avoid possible breakage
in pre v4.16.
