38d7f68851 usbcore: check usb device's state before sending a Set SEL control transfer
Set SEL control urbs cannot be sent to a device in unconfigured state.
This patch adds a check in usb_req_set_sel() to ensure the usb device's
state is USB_STATE_CONFIGURED.

526867c3ca xhci: Fix race between ep halt and URB cancellation
The halted state of a endpoint cannot be cleared over CLEAR_HALT from a
user process, because the stopped_td variable was overwritten in the
handle_stopped_endpoint() function. So the xhci_endpoint_reset() function will
refuse the reset and communication with device can not run over this endpoint.

8b3d45705e usb: Fix xHCI host issues on remote wakeup.
When a device signals remote wakeup on a roothub, and the suspend change
bit is set, the host controller driver must not give control back to the
USB core until the port goes back into the active state.

EHCI accomplishes this by waiting in the get port status function until
the PORT_RESUME bit is cleared:

                        /* stop resume signaling */
                        temp &= ~(PORT_RWC_BITS | PORT_SUSPEND | PORT_RESUME);
                        ehci_writel(ehci, temp, status_reg);
                        clear_bit(wIndex, &ehci->resuming_ports);
                        retval = ehci_handshake(ehci, status_reg,
                                        PORT_RESUME, 0, 2000 /* 2msec */);

Similarly, the xHCI host should wait until the port goes into U0, before
passing control up to the USB core.  When the port transitions from the
RExit state to U0, the xHCI driver will get a port status change event.
We need to wait for that event before passing control up to the USB
core.

After the port transitions to the active state, the USB core should time
a recovery interval before it talks to the device.  The length of that
recovery interval is TRSMRCY, 10 ms, mentioned in the USB 2.0 spec,
section 7.1.7.7.  The previous xHCI code (which did not wait for the
port to go into U0) would cause the USB core to violate that recovery
interval.

This bug caused numerous USB device disconnects on remote wakeup under
ChromeOS and a Lynx Point LP xHCI host that takes up to 20 ms to move
from RExit to U0.  ChromeOS is very aggressive about power savings, and
sets the autosuspend_delay to 100 ms, and disables USB persist.

I attempted to replicate this bug with Ubuntu 12.04, but could not.  I
used Ubuntu 12.04 on the same platform, with the same BIOS that the bug
was triggered on ChromeOS with.  I also changed the USB sysfs settings
as described above, but still could not reproduce the bug under Ubuntu.
It may be that ChromeOS userspace triggers this bug through additional
settings.

ec7e43e2d9 xhci: Ensure a command structure points to the correct trb on the command ring
If a command on the command ring needs to be cancelled before it is handled
it can be turned to a no-op operation when the ring is stopped.
We want to store the command ring enqueue pointer in the command structure
when the command in enqueued for the cancellation case.

Some commands used to store the command ring dequeue pointers instead of enqueue
(these often worked because enqueue happends to equal dequeue quite often)

Other commands correctly used the enqueue pointer but did not check if it pointed
to a valid trb or a link trb, this caused for example stop endpoint command to timeout in
xhci_stop_device() in about 2% of suspend/resume cases.

This should also solve some weird behavior happening in command cancellation cases.

This patch is based on a patch submitted by Sarah Sharp to linux-usb, but
then forgotten:

284d205524 xhci: Fix oops happening after address device timeout
When a command times out, the command ring is first aborted,
and then stopped. If the command ring is empty when it is stopped
the stop event will point to next command which is not yet set.
xHCI tries to handle this next event often causing an oops.

Don't handle command completion events on stopped cmd ring if ring is
empty.

0a5ccb759d bnx2x: prevent masked MCP parities from appearing
During flows which mask block attentions (e.g., register dump) all parities
are masked. However, unlike other blocks the MCP's attention is not masked
inside the block but rather the indication to the driver. If another attention
(e.g., link change) will occour while there's an MCP parity, the driver will
ignore the fact that the parity is masked and erroneously report a parity.

This patch forces the driver to read the MCP masking while checking for
parities.

b60ab990cc dm thin: do not expose non-zero discard limits if discards disabled
Fix issue where the block layer would stack the discard limits of the
pool's data device even if the "ignore_discard" pool feature was
specified.

The pool and thin device(s) still had discards disabled because the
QUEUE_FLAG_DISCARD request_queue flag wasn't set.  But to avoid user
confusion when "ignore_discard" is used: both the pool device and the
thin device(s) have zeroes for all discard limits.

Also, always set discard_zeroes_data_unsupported in targets because they
should never advertise the 'discard_zeroes_data' capability (even if the
pool's data device supports it).

1f28fb9271 drm/radeon/dpm/btc: filter clocks based on voltage/clk dep tables
Filter out mclk and sclk levels higher than listed in the clk
voltage dependency tables.  Supporting these clocks will require
additional driver tweaking that isn't supported yet.

7102e23288 drm/radeon/dpm: fetch the max clk from voltage dep tables helper
This patch adds a helper function to fetch the max clock
from the voltage clock dependecy tables.  Clocks above that
level tend to be unstable and will require additional driver
tweaks in order to work properly.

This patch implemented the helper function to fetch the max clocks
from the dependency tables.  The following patches implement the
per-asic clock filtering.

f3ef11b485 regulator: wm831x-ldo: Fix max_uV for gp_ldo and aldo linear range settings
Fix the linear range settings in commit 5ff26a14c3
"regulator: wm831x-ldo: Convert to use linear ranges".

For wm831x_gp_ldo:
We have below equations for list voltage before converting to linear ranges:

sel <= 0xe:
        volt = 0.9-1.6V in 50mV steps
sel <= 0x1f:
        volt = 1.7-3.3V in 100mV steps

max_uV for the first linear range should be 1600000 rather than 1650000. Fix it.

For wm831x_aldo:
We have below equations for list voltage before converting to linear ranges:

sel <= 0xc:
        volt = 1-1.6V in 50mV steps
sel <= 0x1f
        volt = 1.7-3.5V in 100mV steps

max_uV for the first linear range should be 1600000 rather than 1650000. Fix it.

0afbd74a16 bnx2x: 57840 non-external loopback test fail on 1G
when 1G-optic module was plugged in, internal loopback test failed because the
driver used to check the optic module (with no need), and for 1G optic module,
the link speed was forced down to 1G, while the XMAC (10G MAC) was enabled.
This patch avoid accessing optic module in case internal loopback was selected,
and update the link speed in case 1G optic module was detected during init
stage.

b6a9c1ef3d bnx2x: Generalize KR work-around
Previously, in case of KR link down, the driver would reset the PHY and restart
auto negotiation only when old Warpcore microcode was used (below D108).
This patch comes to generalize this by keep trying to restart KR link,
regardless of Warpcore microcode, since it was found that it solves another link
issue which source is a link-partner. As part of this change, the signal
detect is no longer a condition to apply the work-around to cover this new case.
Like before, as long as the link is down, AN will be restarted every 2 seconds.

'samples' is 64bit operant, but do_div() second parameter is 32.
do_div silently truncates high 32 bits and calculated result
is invalid.

In case if low 32bit of 'samples' are zeros then do_div() produces
