2011-11-11drm: try to restore previous CRTC config if mode set failsJesse Barnes1-0/+13
We restore the CRTC, encoder, and connector configurations, but if the mode set failed, the attached display may have been turned off, so we need to try set_config again to restore things to the way they were.

2011-11-11drm: serialize access to list of debugfs filesMarcin Slusarz3-5/+16
Nouveau, when configured with debugfs, creates debugfs files for every channel, so structure holding list of files needs to be protected from simultaneous changes by multiple threads. Without this patch it's possible to hit kernel oops in drm_debugfs_remove_files just by running a couple of xterms with looped glxinfo.

2011-11-11drm/radeon: Make sure CS mutex is held across GPU reset.Michel Dänzer3-12/+62
This was only the case if the GPU reset was triggered from the CS ioctl, otherwise other processes could happily enter the CS ioctl and wreak havoc during the GPU reset. This is a little complicated because the GPU reset can be triggered from the CS ioctl, in which case we're already holding the mutex, or from other call paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't allow recursive locking or finding out the mutex owner, so we need to handle this with helper functions which allow recursive locking from the same process.

2011-11-11ARM: mach-shmobile: cpuidle single/global and last_state fixesMagnus Damm3-40/+30
The following commits break cpuidle on SH-Mobile ARM: 46bcfad cpuidle: Single/Global registration of idle states e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state This patch remedies these issues by up-porting the SH-Mobile code to fit with the above introduced framework changes. It is worth noting that the new code becomes significantly cleaner, so these framework changes are very welcome. At the same time this breakage could probably have been avoided by grepping for "last_state" and "cpuidle_register_driver".

2011-11-11drivers: sh: Generalize runtime PM platform stub.Paul Mundt3-1/+9
The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.

2011-11-10Btrfs: only map pages if we know we need them when reading the space cacheJosef Bacik1-7/+10
People have been running into a warning when loading space cache because the page is already mapped when trying to read in a bitmap. The way we read in entries and pages is kind of convoluted, so fix it so that io_ctl_read_entry maps the entries if it needs to, and if it hits the end of the page it simply unmaps the page. That way we can unconditionally unmap the io_ctl before reading in the bitmap and we should stop hitting these warnings.

2011-11-10Btrfs: fix orphan backref nodesMiao Xie1-0/+2
If the root node of a fs/file tree is in the block group that is being relocated, but the others are not in the other block groups. when we create a snapshot for this tree between the relocation tree creation ends and ->create_reloc_tree is set to 0, Btrfs will create some backref nodes that are the lowest nodes of the backrefs cache. But we forget to add them into ->leaves list of the backref cache and deal with them, and at last, they will triggered BUG_ON(). kernel BUG at fs/btrfs/relocation.c:239!

2011-11-10Btrfs: fix unreleased path in btrfs_orphan_cleanup()Miao Xie1-0/+3
When we did stress test for the space relocation, the deadlock happened. By debugging, We found it was caused by the carelessness that we forgot to unlock the read lock of the extent buffers in btrfs_orphan_cleanup() before we end the transaction handle, so the transaction commit task waited the task, which called btrfs_orphan_cleanup(), to unlock the extent buffer, but that task waited the commit task to end the transaction commit, and the deadlock happened.

We disabled the check of NO_PRESENCE bit of the default pin-config in commit f4419172 temporarily. One problem was that the first implementation was wrong -- the bit after the shift must be checked. However, this would still give many regressions on machines with broken BIOS. They set this bit wrongly even on active pins. A workaround is to check whether all pins contain this bit. As far as I've checked, broken BIOSen set this bit on all pins, no matter whether active or not. In such a case, the driver should ignore this bit check.
