* i2c: nomadik: adopt pinctrl supportPatrice Chotard2013-01-281-0/+89
| | | | | | | | | | | | | | | | | | | Amend the I2C nomadik pin controller to optionally take a pin control handle and set the state of the pins to: - "default" on boot, resume and before performing an i2c transfer - "idle" after initial default, after resume default, and after each i2c xfer - "sleep" on suspend() This should make it possible to optimize energy usage for the pins both for the suspend/resume cycle, and for runtime cases inbetween I2C transfers.

* i2c: tegra: add support for Tegra114 SoCLaxman Dewangan2013-01-281-14/+63
| | | | | | | | | | | | | | | | NVIDIA's Tegra114 has following enhanced feature in i2c controller: - Enable/disable control for per packet transfer complete interrupt. Earlier SoCs could not disable this. - Single clock source for standard/fast and HS mode clock speed. The clock divisor for fast/standard mode is added into the i2c controller to meet the HS and standard/fast mode of clock speed from single source. Add support for the above feature to make it functional on T114 SOCs.

* i2c-designware: add minimal support for runtime PMMika Westerberg2013-01-281-0/+10
| | | | | | | | | | | | | In order to save power the device should be put to low power states whenever it is not being used. We implement this by enabling minimal runtime PM support. There isn't much to do for the device itself as it is disabled once the last transfer is completed but subsystem/domain runtime PM hooks can save more power by power gating the device etc. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c-designware: always set the STOP bit after last byteMika Westerberg2013-01-281-2/+14
| | | | | | | | | | | | | | | | If IC_EMPTYFIFO_HOLD_MASTER_EN is set to one, the DesignWare I2C controller doesn't generate STOP on the bus when the FIFO is empty. This violates the rules of Linux I2C stack as it requires that the STOP is issued once the i2c_transfer() is finished. However, there is no way to detect this from the hardware registers, so we must make sure that the STOP bit is always set once the last byte of the last message is transferred.

| * Btrfs: fix repeated delalloc work allocationMiao Xie2013-01-241-14/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/ btrfs_queue_worker for this inode, and then it locks the list, checks the head of the list again. But because we don't delete the first inode that it deals with before, it will fetch the same inode. As a result, this function allocates a huge amount of btrfs_delalloc_work structures, and OOM happens. Fix this problem by splice this delalloc list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First, though the current transaction->aborted check can stop the commit early and avoid unnecessary operations, it is too early, and some transaction handles don't end, those handles may set transaction->aborted after the check. Second, when we commit the transaction, we will wake up some worker threads to flush the space cache and inode cache. Those threads also allocate some transaction handles and may set transaction->aborted if some serious error happens. So we need more check for ->aborted when committing the transaction. Fix it.

| | | | | | | | | | | | | | | | | | | | | | | | I noticed a WARN_ON going off when adding csums because we were going over the amount of csum bytes that should have been allowed for an ordered extent. This is a leftover from when we used to hold the csums privately for direct io, but now we use the normal ordered sum stuff so we need to make sure and check if we've moved on to another extent so that the csums are added to the right extent. Without this we could end up with csums for bytenrs that don't have extents to cover them yet. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

| * Btrfs: fix panic when recovering tree logJosef Bacik2013-01-241-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A user reported a BUG_ON(ret) that occured during tree log replay. Ret was -EAGAIN, so what I think happened is that we removed an extent that covered a bitmap entry and an extent entry. We remove the part from the bitmap and return -EAGAIN and then search for the next piece we want to remove, which happens to be an entire extent entry, so we just free the sucker and return. The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The user used btrfs-zero-log so I'm not 100% sure this is what happened so I've added a WARN_ON() to catch the other possibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Balance pause/resume logic got broken by 5ac00add (went in into 3.8-rc1 as part of dev-replace merge). Offending commit took a stab at making mutually exclusive volume operations (add_dev, rm_dev, resize, balance, replace_dev) not block behind volume_mutex if another such operation is in progress and instead return an error right away. Balancing front-end relied on the blocking behaviour, so the fix is ugly, but short of a complete rework, it's the best we can do.

Regardless, this error handling should be cleaned up to handle other reasonable errors (ENOMEM, EIO; whatever).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running xfstests 83 in a loop would sometimes fail the fsck. This happens because if we invalidate a page that already has an ordered extent setup for it we will complete the ordered extent ourselves, assuming that the truncate will clean everything up. The problem with this is there is plenty of time for the truncate to fail after we've done this work. So to fix this we need to add the orphan item first to make sure the cleanup gets done properly, and then we can truncate the pagecache and all that stuff and be safe. This fixes the btrfsck failures I was seeing while running 83 in a loop. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
