2012-09-13apple-gmux: Fix index read functionsBernhard Froemel
Study of Apple's binary driver revealed that the GMUX_READ_PORT should be written between calls to gmux_index_wait_ready and gmux_index_wait_complete (i.e., the new index protocol must be followed). If this is not done correctly, the indexed gmux device only partially accepts writes which lead to problems concerning GPU switching.

Commit a334872224a67b614dc888460377862621f3dac7 added afex support but lacked several logical changes. This lack can cause afex to crash, and also have a slight effect on other flows (i.e., driver always assumes the Tx ring has less available buffers than what it actually has).

2012-09-13drm/radeon: make 64bit fences more robust v3Christian König
Only increase the higher 32bits if we really detect a wrap around. v2: instead of increasing the higher 32bits just use the higher 32bits from the last emitted fence. v3: also use last emitted fence value as upper limit. The intention of this patch is to make fences as robust as they where before introducing 64bit fences. This is necessary because on older systems it looks like the fence value gets corrupted on initialization. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=51344 Should also fix: https://bugs.freedesktop.org/show_bug.cgi?id=54129 https://bugs.freedesktop.org/show_bug.cgi?id=54662 https://bugzilla.redhat.com/show_bug.cgi?id=846505 https://bugzilla.redhat.com/show_bug.cgi?id=845639 3.5 needs a separate patch due to changes in the fence code.

2012-09-13net: qmi_wwan: call subdriver with control intf onlyBjørn Mork
This fixes a hang on suspend due to calling wdm_suspend on the unregistered data interface. The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

2012-09-13net_sched: gred: actually perform idling in WRED modeDavid Ward
gred_dequeue() and gred_drop() do not seem to get called when the queue is empty, meaning that we never start idling while in WRED mode. And since qidlestart is not stored by gred_store_wred_set(), we would never stop idling while in WRED mode if we ever started. This messes up the average queue size calculation that influences packet marking/dropping behavior. Now, we start WRED mode idling as we are removing the last packet from the queue. Also we now actually stop WRED mode idling when we are enqueuing a packet.

q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order to pass q->vars.qavg as the backlog value, we need to un-scale it. Additionally, the qave value returned via netlink should not be Wlog scaled, so we need to un-scale the result of red_calc_qavg(). This caused artificially high values for "Average Queue" to be shown by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

2012-09-13time: Fix timeekeping_get_ns overflow on 32bit systemsJohn Stultz
Daniel Lezcano reported seeing multi-second stalls from keyboard input on his T61 laptop when NOHZ and CPU_IDLE were enabled on a 32bit kernel. He bisected the problem down to commit 1e75fa8be9fb6 ("time: Condense timekeeper.xtime into xtime_sec"). After reproducing this issue, I narrowed the problem down to the fact that timekeeping_get_ns() returns a 64bit nsec value that hasn't been accumulated. In some cases this value was being then stored in timespec.tv_nsec (which is a long). On 32bit systems, with idle times larger then 4 seconds (or less, depending on the value of xtime_nsec), the returned nsec value would overflow 32bits. This limited kept time from increasing, causing timers to not expire. The fix is to make sure we don't directly store the result of timekeeping_get_ns() into a tv_nsec field, instead using a 64bit nsec value which can then be added into the timespec via timespec_add_ns().

2012-09-13GFS2: Take account of blockages when using reserved blocksSteven Whitehouse
The claim_reserved_blks() function was not taking account of the possibility of "blockages" while performing allocation. This can be caused by another node allocating something in the same extent which has been reserved locally. This patch tests for this condition and then skips the remainder of the reservation in this case. This is a relatively rare event, so that it should not affect the general performance improvement which the block reservations provide. The claim_reserved_blks() function also appears not to be able to deal with reservations which cross bitmap boundaries, but that can be dealt with in a future patch since we don't generate boundary crossing reservations currently.

2012-09-13ahci: Add JMicron 362 device IDsBen Hutchings
The JMicron JMB362 controller supports AHCI only, but some revisions use the IDE class code. These need to be matched by device ID. These additions have apparently been included by QNAP in their NAS devices using these controllers.

2012-09-13drm: Drop the NV12M and YUV420M formatsVille Syrjälä
The NV12M/YUV420M formats are identical to the NV12/YUV420 formats. So just remove these duplicated format names. This might look like breaking the ABI, but the code has never actually accepted these formats, so nothing can be using them.

2012-09-13drm/exynos: remove DRM_FORMAT_NV12M from plane moduleInki Dae
this patch removes DRM_FORMAT_NV12M from plane module because this format is same as DRM_FORMAT_NV12. DRM_FORMAT_NV12M will be identified by mode_cmd->handles and mode_cmd->offsets fields internally.
