2012-09-01time: Move ktime_t overflow checking into timespec_valid_strictJohn Stultz
Andreas Bombe reported that the added ktime_t overflow checking added to timespec_valid in commit 4e8b14526ca7 ("time: Improve sanity checking of timekeeping inputs") was causing problems with X.org because it caused timeouts larger then KTIME_T to be invalid. Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid. This patch splits the ktime_t overflow checking into a new timespec_valid_strict function, and converts the timekeeping codes internal checking to use this more strict function.

[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).

2012-08-29drm/radeon/atom: powergating fixes for DCE6Alex Deucher
Power gating is per crtc pair, but the powergating registers should be called individually. The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

2012-08-28Btrfs: fix that repair code is spuriously executed for transid failuresStefan Behrens
If verify_parent_transid() fails for all mirrors, the current code calls repair_io_failure() anyway which means: - that the disk block is rewritten without repairing anything and - that a kernel log message is printed which misleadingly claims that a read error was corrected. This is an example: parent transid verify failed on 615015833600 wanted 110423 found 110424 parent transid verify failed on 615015833600 wanted 110423 found 110424 btrfs read error corrected: ino 1 off 615015833600 (dev /dev/...) It is wrong to ignore the results from verify_parent_transid() and to call repair_eb_io_failure() when the verification of the transids failed. This commit fixes the issue.
