2014-06-19imx-drm: parallel-display: Fix DPMS default state.Denis Carikli
If connector->dpms is left untouched, it defaults to DRM_MODE_DPMS_ON (0). As a result, drm_helper_connector_dpms will exit when it will be asked to set the state to DRM_MODE_DPMS_ON, because it is already set. That issue prevented displays from turning on at boot.

2014-06-20unicore32: Remove ARCH_HAS_CPUFREQ config optionStephen Boyd
This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on unicore32 platforms.

2014-06-19Btrfs: fix deadlock when mounting a degraded fsMiao Xie
The deadlock happened when we mount degraded filesystem, the reproduced steps are following: # mkfs.btrfs -f -m raid1 -d raid1 <dev0> <dev1> # echo 1 > /sys/block/`basename <dev0>`/device/delete # mount -o degraded <dev1> <mnt> The reason was that the counter -- bi_remaining was wrong. If the missing or unwriteable device was the last device in the mapping array, we would not submit the original bio, so we shouldn't increase bi_remaining of it in btrfs_end_bio(), or we would skip the final endio handle. Fix this problem by adding a flag into btrfs bio structure. If we submit the original bio, we will set the flag, and we increase bi_remaining counter, or we don't. Though there is another way to fix it -- decrease bi_remaining counter of the original bio when we make sure the original bio is not submitted, this method need add more check and is easy to make mistake.

2014-06-19btrfs: Skip scrubbing removed chunks to avoid -ENOENT.Qu Wenruo
When run scrub with balance, sometimes -ENOENT will be returned, since in scrub_enumerate_chunks() will search dev_extent in *COMMIT_ROOT*, but btrfs_lookup_block_group() will search block group in *MEMORY*, so if a chunk is removed but not committed, -ENOENT will be returned. However, there is no need to stop scrubbing since other chunks may be scrubbed without problem. So this patch changes the behavior to skip removed chunks and continue to scrub the rest.

When we mounted the filesystem after the crash, we got the following message: BTRFS error (device xxx): block group xxxx has wrong amount of free space BTRFS error (device xxx): failed to load free space cache for block group xxx It is because we didn't update the metadata of the allocated space (in extent tree) until the file data was written into the disk. During this time, there was no information about the allocated spaces in either the extent tree nor the free space cache. when we wrote out the free space cache at this time (commit transaction), those spaces were lost. In fact, only the free space that is used to store the file data had this problem, the others didn't because the metadata of them is updated in the same transaction context. There are many methods which can fix the above problem - track the allocated space, and write it out when we write out the free space cache - account the size of the allocated space that is used to store the file data, if the size is not zero, don't write out the free space cache. The first one is complex and may make the performance drop down. This patch chose the second method, we use a per-block-group variant to account the size of that allocated space. Besides that, we also introduce a per-block-group read-write semaphore to avoid the race between the allocation and the free space cache write out.

The lock_wq wait queue is not used anywhere, therefore just remove it. On a x86_64 system, this reduced sizeof(struct extent_buffer) from 320 bytes down to 296 bytes, which means a 4Kb page can now be used for 13 extent buffers instead of 12.

2014-06-19Btrfs: fix deadlocks with trylock on tree nodesChris Mason
The Btrfs tree trylock function is poorly named. It always takes the spinlock and backs off if the blocking lock is held. This can lead to surprising lockups because people expect it to really be a trylock. This commit makes it a pure trylock, both for the spinlock and the blocking lock. It also reworks the nested lock handling slightly to avoid taking the read lock while a spinning write lock might be held. Signed-off-by: Chris Mason <clm@fb.com>
2014-06-19tty/serial: fix 8250 early console option passing to regular consoleRob Herring
In the conversion to generic early console, the passing of options from the early 8250 console to the regular ttyS console was broken. This resulted in the baud rate changing when switching consoles during boot. This feature allows specifying a single console option on the kernel command line rather than both an early console and regular serial tty console. It would be nice to generalize this feature. However, it only works if the correct baud rate can be probed early which is not the case on many platforms which have non-standard UART clock rates. So for now, this is left as an 8250 specific feature.

2014-06-19tty: Correct INPCK handlingPeter Hurley
If INPCK is not set, input parity detection should be disabled. This means parity errors should not be received from the tty driver, and the data received should be treated normally. SUS v3, 11.2.2, General Terminal Interface - Input Modes, states: "If INPCK is set, input parity checking shall be enabled. If INPCK is not set, input parity checking shall be disabled, allowing output parity generation without input parity errors. Note that whether input parity checking is enabled or disabled is independent of whether parity detection is enabled or disabled (see Control Modes). If parity detection is enabled but input parity checking is disabled, the hardware to which the terminal is connected shall recognize the parity bit, but the terminal special file shall not check whether or not this bit is correctly set." Ignore parity errors reported by the tty driver when INPCK is not set, and handle the received data normally.

2014-06-19serial: Fix IGNBRK handlingPeter Hurley
If IGNBRK is set without either BRKINT or PARMRK set, some uart drivers send a 0x00 byte for BREAK without the TTYBREAK flag to the line discipline, when it should send either nothing or the TTYBREAK flag set. This happens because the read_status_mask masks out the BI condition, which uart_insert_char() then interprets as a normal 0x00 byte. SUS v3 is clear regarding the meaning of IGNBRK; Section 11.2.2, General Terminal Interface - Input Modes, states: "If IGNBRK is set, a break condition detected on input shall be ignored; that is, not put on the input queue and therefore not read by any process." Fix read_status_mask to include the BI bit if IGNBRK is set; the lsr status retains the BI bit if a BREAK is recv'd, which is subsequently ignored in uart_insert_char() when masked with the ignore_status_mask.
