28f74e7177 hwmon/pc87360 separate alarm files: define some constants
Bring hwmon/pc87360 into agreement with
Documentation/hwmon/sysfs-interface.

Patchset adds separate limit alarms for voltages and temps, it also adds
temp[123]_fault files.  On my Soekris, temps 1,2 are unused/unconnected,
so temp[123]_fault = 1,1,0 respectively.  This agrees with
/usr/bin/sensors, which has always shown them as OPEN.  Temps 4,5,6 are
thermistor based, and dont have a fault bit in their status register.

This patch:

2 different kinds of constants added:
- CHAN_ALM_* constants for (later) vin, temp alarm callbacks.
- CHAN_* conversion constants, used in _init_device, partly for RW1C bits

5c62484116 HP-WMI: additional keycode (or typo)
On my HP 2510, pressing the (i) button generates an unknown keycode:
0x213b. So here is a patch adding support for it. However, as it seems
there is already support for a similar button connected to 0x231b as
keycode, I wonder if it could be a typo in the driver?

af936a1606 vmscan: unevictable LRU scan sysctl
This patch adds a function to scan individual or all zones' unevictable
lists and move any pages that have become evictable onto the respective
zone's inactive list, where shrink_inactive_list() will deal with them.

Adds sysctl to scan all nodes, and per node attributes to individual
nodes' zones.

Kosaki: If evictable page found in unevictable lru when write
/proc/sys/vm/scan_unevictable_pages, print filename and file offset of
these pages.

4f98a2fee8 vmscan: split LRU lists into anon & file sets
Split the LRU lists in two, one set for pages that are backed by real file
systems ("file") and one for pages that are backed by memory and swap
("anon").  The latter includes tmpfs.

The advantage of doing this is that the VM will not have to scan over lots
of anonymous pages (which we generally do not want to swap out), just to
find the page cache pages that it should evict.

This patch has the infrastructure and a basic policy to balance how much
we scan the anon lists and how much we scan the file lists.  The big
policy changes are in separate patches.

84dcd59495 USB: fix up problems in the vtusb driver
Add range check on buffer sizes passed in from user space
(max is 8*PAGE_SIZE) which will work for the most common
spectrometers even at pages as small as 1K.

Add kref to vst device structure to preserve reference to the
usb object until we truly are done with it.

71b7497c07 USB: OHCI: fix endless polling behavior
This patch (as1149) fixes an obscure problem in OHCI polling.  In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:

	The interrupt handler is the only place where RHSC status
	gets turned back off;

	The interrupt handler won't turn RHSC status off because it
	doesn't turn off status flags if the corresponding interrupt
	isn't enabled;

	RHSC interrupts will never get enabled because
	ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
	status is on!

As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.

Of course, this is a bug.  The proper thing to do is to turn off RHSC
status just before reading the actual port status values.  That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on.  Possibly both, but that
won't hurt anything.

We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses.  (This re-read has to be done anyway, to post the earlier
write.)  If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.

fd7c519dd4 USB: hub.c: Add initial_descriptor_timeout module parameter for usbcore
This patch adds initial_descriptor_timeout module parameter for usbcore.ko
to allow modify initial 64-byte USB_REQ_GET_DESCRIPTOR timeout for
non-standard devices.

For example, the SATA8000 device from DATAST0R Technology Corp
requires about 10 seconds to send reply (probably it waits until
inserted disk is ready for operation).

Also, this patch adds missing usbcore parameters to
Documentation/kernel-parameters.txt.

49e7cc84a8 USB: Export if an interface driver supports autosuspend.
Create a new sysfs file per interface named supports_autosuspend.  This
file returns true if an interface driver's .supports_autosuspend flag is
set.  It also returns true if the interface is unclaimed (since the USB
core will autosuspend a device if an interface is not claimed).

This new sysfs file will be useful for user space scripts to test whether
a USB device correctly auto-suspends.

eafe5b99f2 USB: EHCI: fix remote-wakeup support for ARC/TDI core
This patch (as1147) fixes the remote-wakeup support for EHCI
controllers using the ARC/TDI "embedded-TT" core.  These controllers
turn off the RESUME bit by themselves when a port resume is complete;
hence we need to keep separate track of which ports are suspended or
in the process of resuming.

The patch also makes a couple of small improvements in ehci_irq(),
replacing reads of the command register with the value already stored
in a local variable.
