This patch incorporates some updates from the review of the
Renesas m66592-udc driver. Updates include:
- Fix some locking bugs; and add a few sparse annotations
- Don't #define __iomem !
- Lots of whitespace fixes (most of the patch by volume)
- Some #include file trimmage
- Other checkpatch.pl and sparse updates
- Alphabetized and slightly-more-informative Kconfig
- Don't use the ID which was assigned to the amd5536udc driver.
- Remove pointless suspend/resume methods updating obsolete field.
- Some section fixups
- Fix some leak bugs
- Fix byteswapping
It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.
This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

USB: fix warning caused by autosuspend counter going negative
This patch (as937) fixes a minor bug in the autosuspend usage-counting
code. Each hub's usage counter keeps track of the number of
unsuspended children. However the current driver increments the
counter after registering a new child, by which time the child may
already have been suspended and caused the counter to go negative.
The obvious solution is to increment the counter before registering
the child.

USB: add "descriptors" binary sysfs attribute
This patch (as934) adds a new readonly binary sysfs attribute file
called "descriptors" for each USB device. The attribute contains the
device descriptor followed by the raw descriptor entry (config plug
subsidiary descriptors) for the current configuration.
Having this information available in fixed-format binary makes life a
lot easier for user programs by avoiding the need to open, read, and
parse multiple sysfs text files.
The information in this attribute file is much like that in usbfs's
device file, but there are some significant differences:
The 2-byte fields in the device descriptor are left in
little-endian byte order, as they appear on the bus and
in the kernel.
Only one raw descriptor set is presented, that of the
current configuration.
Opening this file will not cause a suspended device to be
autoresumed.
The last item in particular should be a big selling point for libusb,
which currently forces all USB devices to be resumed as it scans the
device tree.

This patch (as931b), adapted from a patch by Olav Kongas, makes a small

finish_request() is moved up in the source and is called

after all the active endpoints have been scanned.
The status of a completed URB is kept in a local variable

The driver used to depend on BIOS settings for deciding whether it is OK
to use DMA. However it seems that BIOS doesn't always handle all cases
correctly so just let IDE core to decide about this. It should be a safe

* Always set ->autotune so PIO gets correctly auto-tuned (previously
->autotune was only set when ->dma_base wasn't available, however
->ide_dma_check()/->speedproc() was always trying to tune PIO when

* Move code responsible for programming chipset for PIO mode from
svwks_tune_chipset() to svwks_tune_pio(). Don't tune PIO when tuning
DMA (this is no longer needed since ->autotune is always set now).
* Handle PIO modes early in svwks_tune_chipset() so DMA configuration
registers don't get cleared when programming PIO mode.
* Add sil_tuneproc() wrapper for siimage_tuneproc() which also sets
PIO mode on the device.
* Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
"pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).
* Add code limiting maximum PIO mode according to the pair device capabilities
to sil_tuneproc().
* Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
sil_tuneproc(). This fixes PIO fallback in siimage_config_drive_for_dma() to

tried to set PIO4).

* Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes
from siimage_speedproc()
* Bump driver version.

i386: Allow KVM on i386 nonpae
Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of

Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.
Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed

[PATCH] sched: fix newly idle load balance in case of SMT
In the presence of SMT, newly idle balance was never happening for
multi-core and SMP domains (even when both the logical siblings are
idle).
If thread 0 is already idle and when thread 1 is about to go to idle,
newly idle load balance always think that one of the threads is not idle
and skips doing the newly idle load balance for multi-core and SMP
domains.
This is because of the idle_cpu() macro, which checks if the current
process on a cpu is an idle process. But this is not the case for the
thread doing the load_balance_newidle().
Fix this by using runqueue's nr_running field instead of idle_cpu(). And
also skip the logic of 'only one idle cpu in the group will be doing
load balancing' during newly idle case.

as the BIOS is supposed to set them up properly. This information makes it
easier to find out which temperature channel corresponds to the CPU.

hwmon/w83627ehf: Add support for the VID inputs
The W83627EHF and similar chips have 6 VID input pins, add support
for them. The driver changes the input voltage level automatically
if the current setting is not correct for the detected CPU model.

hwmon/w83627ehf: Fix timing issues
* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.
* When changing a fan clock divider, the corresponding fan speed
measurement register is no longer valid, until the next time the chip
will refresh it. One way to fix this is to pretend that the cache is
still valid for one more period (1.5 second.)

hwmon/w83627ehf: Add error messages for two error cases
If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.
Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.
