This patch (as1483) improves the ehci-hcd driver family by getting rid of the reliance on the hcd->state variable. It has no clear owner and it isn't protected by the usual HCD locks. In its place, the patch adds a new, private ehci->rh_state field to record the state of the root hub. Along the way, the patch removes a couple of lines containing redundant assignments to the state variable. Also, the QUIESCING state simply gets changed to the RUNNING state, because the driver doesn't make any distinction between them. Signed-off-by:

Errata 2 for the isp1760 explains that the chip sometimes does not issue interrupts when an ATL (bulk or control) transfer is completed. There are several issues with the current work-around (SOF interrupts) for this: 1) It seems the chip sometimes does not even set the done bit for a completed transfer, in which case SOF interrupts does not solve the problem since we still check the done map to find out which transfer descriptors to handle. 2) The above point seems to happen only when ATL and SOF interrupts are enabled at the same time. However, disabling ATL interrupts increases the latency between transfer completion and handling. This is very noticeable in the testusb suite, which take several minutes more to run with ATL interrupts disabled. This patch removes the code to switch on SOF interrupts, and instead use a kernel timer to periodically check for "old" descriptors that have their VALID and ACTIVE flags unset, indicating completion, thus avoiding the dependency on the chip's done map (and SOF interrupts) to find transfers affected by this HW bug.

Scanning cannot be run during suspend or hibernation, but if usb-stor-scan freezes another thread waiting on scanning to complete may fail to freeze. However, if usb-stor-scan is left freezable without ever actually freezing then the freezer will wait on it to exit, and threads waiting for scanning to finish will no longer be blocked. One problem with this approach is that usb-stor-scan has a delay to wait for devices to settle (which is currently the only point where it can freeze). To work around this we can request that the freezer send a fake signal when freezing, then use interruptible sleep to wake the thread early when freezing happens. To make this happen, the following changes are made to usb-stor-scan: * Use set_freezable_with_signal() instead of set_freezable() to request a fake signal when freezing * Use wait_event_interruptible_timeout() instead of wait_event_freezable_timeout() to avoid freezing Signed-off-by:

This fixes a regression introduced by commit cdcb725c ("Btrfs: check if there is enough space for balancing smarter"). We can't do 64-bit divides on 32-bit architectures. In cases where we need to divide/multiply by 2 we should just left/right shift respectively, and in cases where theres N number of devices use do_div. Also make the counters u64 to match up with rw_devices. Thanks, Signed-off-by:

Currently HD-audio driver shows the all error ELD byte as an error in the kernel message. This is annoying when the video driver doesn't set the correct ELD from the beginning. e.g. radeon sends a zero-byte data, but we still check ELD with the fixed 128 byte as a workaround for some broken devices, it spews 128-times errors. For avoiding this, the driver aborts reading when the first byte is invalid. In such a case, the whole data is certainly invalid. Signed-off-by:

There is a race between ext4 buffer write and direct_IO read with dioread_nolock mount option enabled. The problem is that we clear PageWriteback flag during end_io time but will do uninitialized-to-initialized extent conversion later with dioread_nolock. If an O_direct read request comes in during this period, ext4 will return zero instead of the recently written data. This patch checks whether there are any pending uninitialized-to-initialized extent conversion requests before doing O_direct read to close the race. Note that this is just a bandaid fix. The fundamental issue is that we clear PageWriteback flag before we really complete an IO, which is problem-prone. To fix the fundamental issue, we may need to implement an extent tree cache that we can use to look up pending to-be-converted extents. Signed-off-by:

Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that MI_FLUSH would flush the TLBs in addition to the rest of the caches indicated in the MI_FLUSH command. However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL. Since we're not doing that yet, go back to the old default so things work. v2: don't forget to actually *clear* the new bit Reviewed-by:

The recent fix for testing dB range at the mixer creation time seems to cause regressions in some devices. In such devices, reading the dB info at probing time gives an error, thus both dBmin and dBmax are still zero, and TLV flag isn't set although the later read of dB info succeeds. This patch adds a workaround for such a case by assuming that the later read will succeed. In future, a similar test should be performed in a case where a wrong dB range is seen even in the later read. Signed-off-by:
