5a9c2cd881 hwmon: Remove in[0-*]_fault from sysfs-interface
Fault files are for hardware failures that can be reported. So far
we've seen chips reporting such failures for temperature sensors and
fans, but not for voltages. Remove in[0-*]_fault for now. It can be
added back later if really needed, but I doubt it.

e04a715e4e hwmon: Add 4 current alarm/beep attributes to sysfs-interface
Add currX_alarm, currX_min_alarm, currX_max_alarm and currX_beep
attributes to the hwmon sysfs API.

currX_min_alarm and currX_max_alarm are already supported by the LTC4215
and LTC4245 drivers. currX_alarm is supported by the LTC4261 driver.

738e5e0536 hwmon: (it87) Export labels for internal sensors
Some voltage sensors can be wired internally to the IT87xxF chip's own

wiring is known by exporting proper labels for these sensors.

5950ec8d3e hwmon: (ltc4245) Expose all GPIO pins as analog voltages
Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

b9783dcebe hwmon: (pc87360) Fix device resource declaration
It's not OK to call platform_device_add_resources() multiple times
in a row. Despite its name, this functions sets the resources, it
doesn't add them. So we have to prepare an array with all the
resources, and then call platform_device_add_resources() once.

Before this fix, only the last I/O resource would be actually
registered. The other I/O resources were leaked.

11ac552477 mm: fix page table unmap for stack guard page properly
We do in fact need to unmap the page table _before_ doing the whole
stack guard page logic, because if it is needed (mainly 32-bit x86 with
PAE and CONFIG_HIGHPTE, but other architectures may use it too) then it
will do a kmap_atomic/kunmap_atomic.

And those kmaps will create an atomic region that we cannot do
allocations in.  However, the whole stack expand code will need to do
anon_vma_prepare() and vma_lock_anon_vma() and they cannot do that in an
atomic region.

Now, a better model might actually be to do the anon_vma_prepare() when
_creating_ a VM_GROWSDOWN segment, and not have to worry about any of
this at page fault time.  But in the meantime, this is the
straightforward fix for the issue.

See https://bugzilla.kernel.org/show_bug.cgi?id=16588 for details.

We can restore module capability after cpuidle is enhanced

01d69a82e1 [IA64] Fix 64-bit atomic routines to return "long"
These have been broken (returning "int") since the dawn of
time. But there were no users that needed the whole value
until commit

 rwsem: wake queued readers when writer blocks on active read lock

made this change:

-           (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK))
-               /* Someone grabbed the sem already */
+           rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
+               /* Someone grabbed the sem for write already */

RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked
at the low order 32-bits. The new code needs to see all 64 bits.
