The number of idle states was wrong.
The POLL idle state (on X86) was missed out:
Number of idle states: 4
Available idle states: C1-NHM C3-NHM C6-NHM
While the POLL is not a real idle state, its
statistics should still be shown. It's now also
explained in a detailed manpage.
This should fix a bug of missing the first idle
state on other archs.

AMD's BKDG (Bios and Kernel Developers Guide) talks in the CPU spec of their
CPU families about PCI registers defined by "device" (slot) and func(tion).
Assuming that CPU specific configuration PCI devices are always on domain
and bus zero a pci_slot_func_init() func which gets the slot and func of
the desired PCI device passed looks like the most convenient way.
This also obsoletes the PCI device id maintenance.

The reada code from scrub was casting down a u64 to
an unsigned long so it could insert it into a radix tree.
What it really wanted to do was cast down the result of a shift, instead
of casting down the u64. The bug resulted in trying to insert our
reada struct into the wrong place, which caused soft lockups and other
problems.

{g|s}etnumtcs() today returns a u8 that is only used by the DCB code
to verify no error occurred. Today the driver implementations return
negative error codes which end up being non-zero so the logic works

It seems the USB device ID 0bda:8192 is wrongly assigned to the

So this patch moves this device ID from the rtl8192u staging
driver to the rtl8712 staging driver.
This patch was tested with a Radicom WIFIHU embedded wireless
module with a RTL8191SU chip and the USB device ID 0bda:8192.
Without the patch the rtl8192u driver claims this device, but
it does not work. With the patch the rtl8712 driver services
this device and it works.

The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

As the coverity checker puts it:
"Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc"
and then casting the return value to "struct usb_descriptor_header **"
is suspicious. ... In this particular case sizeof(struct

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.
Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
cp210x_port_private struct, and use the interface number there in the
usb_control_message wIndex param

Problem is that CTRL_PHY_CLK_VALID bit seems not to be present
on all Freescale ehci implementations, at least P1022 does not

memory management on DWC3 driver by using dev_xxx functions, a few
optimizations to IRQ handling by dropping memcpy() and using bitshifts, a fix
for TI's OMAP5430 TX Fifo Allocation, two fixes on USB2 test mode
implementation (one on debugfs and one on ep0), and several minor changes such
as whitespace cleanups, simplification of a few parts of the code, decreasing a
long delay to something a bit saner, dropping a header which was included twice

The highlight on this merge is the support for Samsung's Exynos platform,

Note that Samsung Exynos glue layer will only compile on platforms which
provide implementation for the clk API for now. Once Samsung supports
pm_runtime, that limitation can be dropped from the Makefile.
