2013-01-25sh-pfc: Move platform device and driver to the coreLaurent Pinchart
The pinctrl module registers both a platform device and a platform driver. The only purpose of this awkward construction is to have a device to pass to the pinctrl registration function. As a first step to get rid of this hack, move the platform device and driver from the pinctrl module to the core. The platform device will then be moved to arch code.

2013-01-25sh-pfc: Merge PFC core and gpioLaurent Pinchart
The PFC core calls the gpio module gpiochip registration in its register_sh_pfc() function, itself called at arch initialization time. If the gpio module isn't present then the gpiochip will never be registered. As the gpio module can only be present at arch initialization time if it's builtin, there's no point in allowing to build it as a module. Make it a boolean option, and initialize it synchronously with the core if selected.

2013-01-25sh-pfc: Merge PFC core and pinctrlLaurent Pinchart
The PFC core is only used by the pinctrl and gpio modules. As the gpio module depends on the pinctrl module, the pinctrl module will always be present if the core gets used.

A careless look at the code shows that the last entry in the pinmux_gpios seems to be GPIO_FN_IRQOUT.

2013-01-24Btrfs: fix repeated delalloc work allocationMiao Xie
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.

2013-01-24Btrfs: fix missed transaction->aborted checkMiao Xie
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.

2013-01-24Btrfs: put csums on the right ordered extentJosef Bacik
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>

2013-01-24Btrfs: fix panic when recovering tree logJosef Bacik
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.

2013-01-24Btrfs: do not allow logged extents to be merged or removedJosef Bacik
We drop the extent map tree lock while we're logging extents, so somebody could come in and merge another extent into this one and screw up our logging, or they could even remove us from the list which would keep us from logging the extent or freeing our ref on it, so we need to make sure to not clear LOGGING until after the extent is logged, and then we can merge it to adjacent extents.
