Dmitry Kasatkin reports:
"kernel-devel package with kernel headers have no <include/xen>
directory if XEN is disabled. Modules which inclide asm/io.h won't
compile.
XEN related content is behind the CONFIG_XEN flag in the io.h. And
<xen/xen.h> should be also behind CONFIG_XEN flag."
So move the include of <xen/xen.h> down into the section that is
conditional on CONFIG_XEN.

When a Xen Dom0 kernel boots on a hypervisor, it gets access
to the raw-hardware ACPI tables. While it parses the idle tables
for the hypervisor's beneift, it uses HLT for its own idle.
Rather than have xen scribble on pm_idle and access default_idle,
have it simply disable_cpuidle() so acpi_idle will not load and
architecture default HLT will be used.

The Moorestown (MRST) Power Management Unit (PMU) driver
directs the SOC power states in the "Langwell" south complex (SCU).
It hooks pci_platform_pm_ops[] and thus observes all PCI ".set_state"
requests. For devices in the SC, the pmu driver translates those
PCI requests into the appropriate commands for the SCU.
The PMU driver helps implement S0i3, a deep system idle power idle state.
Entry into S0i3 is via cpuidle, just like regular processor c-states.
S0i3 depends on pre-conditions including uni-processor, graphics off,
and certain IO devices in the SC must be off. If those pre-conditions
are met, then the PMU allows cpuidle to enter S0i3, otherwise such requests
are demoted, either to Atom C4 or Atom C6.
This driver is based on prototype work by Bruce Flemming,
Illyas Mansoor, Rajeev D. Muralidhar, Vishwesh M. Rudramuni,
Hari Seshadri and Sujith Thomas. The current driver also
includes contributions from H. Peter Anvin, Arjan van de Ven,
Kristen Accardi, and Yong Wang.
Thanks for additional review feedback from Alan Cox and Randy Dunlap.

cmpxchg() is widely used by lockless code, including NMI-safe lockless
code. But on some architectures, the cmpxchg() implementation is not
NMI-safe, on these architectures the lockless code may need a
spin_trylock_irqsave() based implementation.
This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that
NMI-safe lockless code can depend on it or provide different
implementation according to it.
On many architectures, cmpxchg is only NMI-safe for several specific
operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch
only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

This is the same as fd8a7de1 "x86: cpu-hotplug: Prevent softirq wakeup

Unlike on x86 this doesn't fix a bug on s390 since we do not have
threaded interrupt handlers. However we want to keep the same
initialization order like on x86. This should prevent bugs caused by
code which assumes (and relies on) the init order is the same on each
architecture.

With this patch a new S390 shutdown trigger "restart" is added. If under
z/VM "systerm restart" is entered or under the HMC the "PSW restart" button
is pressed, the PSW located at 0 (31 bit) or 0x1a0 (64 bit) bit is loaded.
Now we execute do_restart() that processes the restart action that is
defined under /sys/firmware/shutdown_actions/on_restart. Currently the
following actions are possible: reipl (default), stop, vmcmd, dump, and
dump_reipl.
