System Power Management Interface (SPMI) is a specification
developed by the MIPI (Mobile Industry Process Interface) Alliance
optimized for the real time control of Power Management ICs (PMIC).SPMI is a two-wire serial interface that supports up to 4 master
devices and up to 16 logical slaves.The framework supports message APIs, multiple busses (1 controller
per bus) and multiple clients/slave devices per controller.Signed-off-by: Kenneth Heitke

On Gen2 firmware, Hyper-V does not emulate the PCI bus. However, the MMIO
information is packaged up in DSDT. Extract this information and export it
for use by the synthetic framebuffer driver. This is the only driver that
needs this currently.In this version of the patch mmio, I have updated the hyperv header file
(linux/hyperv.h) with mmio definitions.Signed-off-by: K. Y. Srinivasan

This patch adds the hyperv.h header to the uapi folder, and adds it to the Kbuild file.

Pull ACPI and power management fixes and cleanups from Rafael Wysocki:
- ACPI device hotplug fix preventing ACPI drivers from binding to device
objects that acpi_bus_trim() has been called for and the devices
represented by them may not be operational.- Recent cpufreq changes related to the "boost" (turbo) feature broke
the acpi-cpufreq error code path causing a NULL pointer dereference
to occur on some systems. Fix from Konrad Rzeszutek Wilk.- The log level of a CPU initialization error message added recently
needs to be reduced, because the particular BIOS issue indicated by
it turns out to be widespread and doesn't really matter for the
majority of systems having it. From Jiang Liu.- The regulator API needs to be told to stay away from things on systems
with ACPI BIOSes or it may conflict with the BIOS' own handling of
voltage regulators. Fix from Mark Brown that works around a 3.13
regression in lm90 on PCs occuring if the regulator API is enabled.- Prevent the Exynos4 devfreq driver from being built on multiplatform,
because it depends on things that aren't available during such builds.
From Sachin Kamat.- Upstream ACPICA doesn't use the bool type as defined in the kernel,
so modify the kernel's ACPICA code to follow the upstream in that
respect (only one variable definition is affected) to reduce
divergences between the two. From Lv Zheng.- Make the ACPI device PM code use ACPI_COMPANION() instead of its own
routine doing the same thing (and invokng ACPI_COMPANION() in the
process).- Modify some routines in the ACPI processor driver to follow the
common convention and return negative integers on errors. From

The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
for blkback and future netback patches it just cause a lock contention, as
those pages never go to userspace. Therefore this series does the following:
- the original functions were renamed to __gnttab_[un]map_refs, with a new
parameter m2p_override
- based on m2p_override either they follow the original behaviour, or just set
the private flag and call set_phys_to_machine
- gnttab_[un]map_refs are now a wrapper to call __gnttab_[un]map_refs with
m2p_override false
- a new function gnttab_[un]map_refs_userspace provides the old behaviourIt also removes a stray space from page.h and change ret to 0 if
XENFEAT_auto_translated_physmap, as that is the only possible return value
there.v2:
- move the storing of the old mfn in page->index to gnttab_map_refs
- move the function header update to a separate patchv3:
- a new approach to retain old behaviour where it needed
- squash the patches into onev4:
- move out the common bits from m2p* functions, and pass pfn/mfn as parameter
- clear page->private before doing anything with the page, so m2p_find_override
won't race with thisv5:
- change return value handling in __gnttab_[un]map_refs
- remove a stray space in page.h
- add detail why ret = 0 now at some placesv6:
- don't pass pfn to m2p* functions, just get it locallySigned-off-by: Zoltan Kiss

(thanks to Kinglong Mee).
- Fix some gss-proxy problems (thanks Jeff Layton).

On ARM, address size can be 32 bits or 64 bits (if CONFIG_ARCH_PHYS_ADDR_T_64BIT
is enabled).
We can't assume that the grant frame base address will always fits in an
unsigned long. Use phys_addr_t instead of unsigned long as argument for
gnttab_setup_auto_xlat_frames.Signed-off-by: Julien Grall

This patch fixes a percpu_ref_put race for se_lun->lun_ref in
transport_lun_remove_cmd() where ->lun_ref could end up being
put more than once per command via different target completion
and fabric release contexts.It adds a cmpxchg() for se_cmd->lun_ref_active to ensure that
percpu_ref_put() is only ever called once per se_cmd.This bug was manifesting itself as a LUN shutdown regression
bug in >= v3.13 code, where percpu_ref_kill() would end up
hanging indefinately due to the incorrect percpu_ref count.(Change se_cmd->lun_ref_active from bool -> int to force at
least a 4-byte cmpxchg with MIPS ll/sc ins. - Fengguang)Reported-by: Tommy Apel
