Pull powerpc fixes from Michael Ellerman:
"A small batch of fixes, about 50% tagged for stable and the rest for
recently merged code.

There's one more fix for the >128T handling on hash. Once a process
had requested a single mmap above 128T we would then always search
above 128T. The correct behaviour is to consider the hint address in
isolation for each mmap request.

Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in
VAS, a fix for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly
identify P9 DD2.1 but in code that is currently not used by default.

The "rpm" has been kept for backward compatibility since pre-git era.
I am planning to remove it after the Linux 4.18 release. Annouce the
end of the support, prompting to use "rpm-pkg" instead.

If you use "rpm", it will work like "rpm-pkg", but warning messages
will be displayed as follows:

WARNING: "rpm" target will be removed after Linux 4.18
Please use "rpm-pkg" instead.

Pull SCSI target updates from Nicholas Bellinger:

"This series is predominantly bug-fixes, with a few small improvements
that have been outstanding over the last release cycle.

As usual, the associated bug-fixes have CC' tags for stable.

Also, things have been particularly quiet wrt new developments the
last months, with most folks continuing to focus on stability atop 4.x
stable kernels for their respective production configurations.

Also at this point, the stable trees have been synced up with
mainline. This will continue to be a priority, as production users
tend to run exclusively atop stable kernels, a few releases behind
mainline.

The highlights include:

- Fix PR PREEMPT_AND_ABORT null pointer dereference regression in
v4.11+ (tangwenji)

- Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)

- Add netlink command reply supported option for each device (Kenjiro
Nakayama)

- cxgbit: Abort the TCP connection in case of data out timeout (Varun
Prakash)

- Fix PR/ALUA file path truncation (David Disseldorp)

- Fix double se_cmd completion during ->cmd_time_out (Mike Christie)

- Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly +
nab)

- Fix quiese during transport_write_pending_qf endless loop (nab)

- Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+
(Don White + nab)"

I got the logic wrong in the DT CPU features code when I added the
Power9 DD2.1 feature. We should be setting the bit if we detect a
DD2.1, not clearing it if we detect a DD2.0.

This code isn't actually exercised at the moment so nothing is
actually broken.

This is more or less a revert of commit 2c82878b0cb3 ("KVM: VMX: require
virtual NMI support", 2017-03-27); it turns out that Core 2 Duo machines
only had virtual NMIs in some SKUs.

The revert is not trivial because in the meanwhile there have been several
fixes to nested NMI injection. Therefore, the entire vNMI state is moved
to struct loaded_vmcs.

Another change compared to before the patch is a simplification here:

if (unlikely(!cpu_has_virtual_nmis() && vmx->soft_vnmi_blocked &&
!(is_guest_mode(vcpu) && nested_cpu_has_virtual_nmis(
get_vmcs12(vcpu))))) {

The final condition here is always true (because nested_cpu_has_virtual_nmis
is always false) and is removed.
