0d204c34e8 thinkpad-acpi: basic ALSA mixer support (v2)
Add the basic ALSA mixer functionality.  The mixer is event-driven,
and will work fine on IBM ThinkPads.  I expect Lenovo ThinkPads will
cause some trouble with the event interface.

Heavily based on work by Lorne Applebaum <lorne.applebaum@gmail.com>
and ideas from Matthew Garrett <mjg@redhat.com>.

c7ac6291ea thinkpad-acpi: disable volume control
Disable volume control by default.  It can be enabled at module load
time by a module parameter (volume_control=1).

The audio control mixer that thinkpad-acpi interacts with is fully
functional without any drivers, and operated by hotkeys.

The idea behind the console audio control is that the human operator
is the only one that can interact with it.  The ThinkVantage suite in
Windows does not allow any software-based overrides, and only does OSD
(on-screen-display) functions.

The Linux driver will, with the addition of the ALSA interface, try to
follow and enforce the ThinkVantage UI design:

The user is supposed to use the keyboard hotkeys to interact with the
console audio control.  The kernel and the desktop environment is
supposed to cooperate to provide proper user feedback through
on-screen-display functions.

Distros are urged to not to enable volume control by default.
Enabling this must be a local admin's decision.  This is the reason
why there is no Kconfig option.

Keep in mind that all ThinkPads have a normal, main mixer (AC97 or
HDA) for regular software-based audio control.  We are not talking
about that mixer here.

Advanced users are, of course, free to enable volume control and do as
they please.

a112ceee67 thinkpad-acpi: support MUTE-only ThinkPads
Lenovo removed the extra mixer since the T61 and thereabouts.
Newer Lenovo models only have the mute gate function, and leave
the volume control to the HDA mixer.

Until a way to automatically query the firmware about its audio
control capabilities is discovered (there might not be any), use a
white/black list.

We will likely need to ask T60 (old and new model) and Z60/Z61 users
whether they have volume control to populate the black/white list.
Meanwhile, provide a volume_capabilities parameter that can be used to
override the defaults.

329e4e18df thinkpad-acpi: volume subdriver rewrite
I don't trust the coupled EC writes and SMI calls the current volume
control code does very much, although it is exactly what the IBM DSDTs
seem to do (they never do more than a single step though).

Change the driver to stop issuing SMIs, and just drive the EC directly
to the desired level (DSDTs seem to confirm this will work even on
very old models like the 570 and 600e/x).

We checkpoint directly to NVRAM (this can be turned off) at
suspend/shutdown/driver unload, which from what I can see in tbp,
should also work on every ThinkPad.

Add control of fan minimum turn-on output levels, decoupling it from the
fan turn-off output level.  Add control of rate of change of fan output
level.  These in turn allow lower turn-off rotor speed and smoother
transitions for better thermal and acoustic control authority.  Add
support for constant fan speed and proportional-response operations modes.

4614a696bd procfs: allow threads to rename siblings via /proc/pid/tasks/tid/comm
Setting a thread's comm to be something unique is a very useful ability
and is helpful for debugging complicated threaded applications.  However
currently the only way to set a thread name is for the thread to name
itself via the PR_SET_NAME prctl.

However, there may be situations where it would be advantageous for a
thread dispatcher to be naming the threads its managing, rather then
having the threads self-describe themselves.  This sort of behavior is
available on other systems via the pthread_setname_np() interface.

This patch exports a task's comm via proc/pid/comm and
proc/pid/task/tid/comm interfaces, and allows thread siblings to write to
these values.

ea63763959 nommu: fix malloc performance by adding uninitialized flag
The NOMMU code currently clears all anonymous mmapped memory.  While this
is what we want in the default case, all memory allocation from userspace
under NOMMU has to go through this interface, including malloc() which is
allowed to return uninitialized memory.  This can easily be a significant
performance penalty.  So for constrained embedded systems were security is
irrelevant, allow people to avoid clearing memory unnecessarily.

This also alters the ELF-FDPIC binfmt such that it obtains uninitialised
memory for the brk and stack region.

d0f209f68f ksm: remove unswappable max_kernel_pages
Now that ksm pages are swappable, and the known holes plugged, remove
mention of unswappable kernel pages from KSM documentation and comments.

Remove the totalram_pages/4 initialization of max_kernel_pages.  In fact,
remove max_kernel_pages altogether - we can reinstate it if removal turns
out to break someone's script; but if we later want to limit KSM's memory
usage, limiting the stable nodes would not be an effective approach.

dee5d0d518 mm: add numa node symlink for memory section in sysfs
Commit c04fc586c (mm: show node to memory section relationship with
symlinks in sysfs) created symlinks from nodes to memory sections, e.g.

/sys/devices/system/node/node1/memory135 -> ../../memory/memory135

If you're examining the memory section though and are wondering what node
it might belong to, you can find it by grovelling around in sysfs, but
it's a little cumbersome.

Add a reverse symlink for each memory section that points back to the
node to which it belongs.

4faf8d950e hugetlb: handle memory hot-plug events
Register per node hstate attributes only for nodes with memory.  As
suggested by David Rientjes.

With Memory Hotplug, memory can be added to a memoryless node and a node
with memory can become memoryless.  Therefore, add a memory on/off-line
notifier callback to [un]register a node's attributes on transition
to/from memoryless state.

N.B.,  Only tested build, boot, libhugetlbfs regression.
       i.e., no memory hotplug testing.

bb86a7338b page-types: exit early when invoked with -d|--describe
On a system with large amount of memory (256GB), invoking page-types can
take quite a long time, which is unreasonable considering the user only
wants a description of the flags:

	# time ./page-types -d 0x10
	0x0000000000000010	____D_____________________________	dirty

	real	0m34.285s
	user	0m1.966s
	sys	0m32.313s

This is because we still walk the entire address range.

Exiting early seems like a reasonble solution:

# time ./page-types -d 0x10
	0x0000000000000010	____D_____________________________	dirty

	real	0m0.007s

dcfe730c60 page-types: learn to describe flags directly from command line
Teach page-types to describe page flags directly from the command line.

Why is this useful?  For instance, if you're using memory hotplug and see
this in /var/log/messages:

	kernel: removing from LRU failed 3836dd0/1/1e00000000000010

It would be nice to decode those page flags without staring at the source.

Example usage and output:

# Documentation/vm/page-types -d 0x10
0x0000000000000010	____D_____________________________	dirty

# Documentation/vm/page-types -d anon

06f8bda832 x86: Remove usedac in feature-removal-schedule.txt
The reason of removal, "replaced by allowdac and no dac
combination" is incorrect. There is no way to do the same thing
with "allowdac" and "nodac" combination.

The usedac option enables us to stop via_no_dac() setting
forbid_dac to 1. That is, someone who uses VIA bridges can use
DAC with this option even if some of VIA bridges seem to be
broken about DAC.

ece5cff0da md: Support write-intent bitmaps with externally managed metadata.
In this case, the metadata needs to not be in the same
sector as the bitmap.
md will not read/write any bitmap metadata.  Config must be
done via sysfs and when a recovery makes the array non-degraded
again, writing 'true' to 'bitmap/can_clear' will allow bits in
the bitmap to be cleared again.

43a705076e md: support updating bitmap parameters via sysfs.
A new attribute directory 'bitmap' in 'md' is created which
contains files for configuring the bitmap.
'location' identifies where the bitmap is, either 'none',
or 'file' or 'sector offset from metadata'.
Writing 'location' can create or remove a bitmap.
Adding a 'file' bitmap this way is not yet supported.
'chunksize' and 'time_base' must be set before 'location'
can be set.

'chunksize' can be set before creating a bitmap, but is
currently always over-ridden by the bitmap superblock.

'time_base' and 'backlog' can be updated at any time.

To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

a0bb108112 USB: usb-storage: add BAD_SENSE flag
This patch (as1311) fixes a problem in usb-storage: Some devices are
pretty broken when it comes to reporting sense data.  The information
they send back indicates that they have more than 18 bytes of sense
data available, but when the system asks for more than 18 they fail or
hang.  The symptom is that probing fails with multiple resets.

The patch adds a new BAD_SENSE flag to indicate that usb-storage
should never ask for more than 18 bytes of sense data.  The flag can
be set in an unusual_devs entry or via the "quirks=" module parameter,
and it is set automatically whenever a REQUEST SENSE command for more
than 18 bytes fails or times out.

An unusual_devs entry is added for the Agfa photo frame, which uses a
Prolific chip having this bug.

8e4ceb38eb USB: prepare for changover to Runtime PM framework
This patch (as1303) revises the USB Power Management infrastructure to
make it compatible with the new driver-model Runtime PM framework:

	Drivers are no longer allowed to access intf->pm_usage_cnt
	directly; the PM framework manages its own usage counters.

	usb_autopm_set_interface() is eliminated, because it directly
	sets intf->pm_usage_cnt.

	usb_autopm_enable() and usb_autopm_disable() are eliminated,
	because they call usb_autopm_set_interface().

	usb_autopm_get_interface_no_resume() and
	usb_autopm_put_interface_no_suspend() are added.  They
	correspond to pm_runtime_get_noresume() and
	pm_runtime_put_noidle() in the PM framework.

	The power/level attribute no longer accepts "suspend", only
	"on" and "auto".  The PM framework doesn't allow devices to be
	forced into a suspended mode.

The hub driver contains the only code that violates the new

fb34d53752 USB: remove the auto_pm flag
This patch (as1302) removes the auto_pm flag from struct usb_device.
The flag's only purpose was to distinguish between autosuspends and
external suspends, but that information is now available in the
pm_message_t argument passed to suspend methods.

a1a541d86f ACPI: support customizing ACPI control methods at runtime
Introduce a new debugfs I/F (/sys/kernel/debug/acpi/custom_method) for ACPI,
which can be used to customize the ACPI control methods at runtime.

We can use this to debug the AML code level bugs instead of overriding the
whole DSDT table, without rebuilding/rebooting kernel any more.

Detailed description about how to use this debugfs I/F is stated in
Documentation/acpi/method-customizing.txt

d698aa4500 dm snapshot: add merge target
The snapshot-merge target allows a snapshot to be merged back into the
snapshot's origin device.

One anticipated use of snapshot merging is the rollback of filesystems
to back out problematic system upgrades.

This patch adds snapshot-merge target management to both
dm_snapshot_init() and dm_snapshot_exit().  As an initial place-holder,
snapshot-merge is identical to the snapshot target.  Documentation is
provided.

Users on the list recently complained about differences across
filesystems w.r.t. how to mount without a journal replay.

In the discussion it was noted that xfs's "norecovery" option is
perhaps more descriptively accurate than "noload," so let's make
that an alias for ext3.

7669896f49 hwmon: (f71882fg) Add support for the f71889fg (version 2)
This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.

Note that this bit of the patch:
-	val = SENSORS_LIMIT(val, 0, 255);
+
+	if (data->type == f71889fg)
+		val = SENSORS_LIMIT(val, -128, 127);
+	else
+		val = SENSORS_LIMIT(val, 0, 127);

Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.

8918023d40 hwmon: (w83627hf) Drop the force_addr module parameter
This module parameter is there to workaround broken BIOS. I'm not even
sure if it was used in the past 5 years, and it gets in the way of
converting the driver to the MFD infrastructure. So tell the users how
they can do the same from user-space.
