| | | | | | | | | | | | | | | | | | | | | | intel_framebuffer_init does some basic sanity checking of the pixel format, but is used by the plane code in addition to the primary crtc. So it needs to contain any formats used in either place. Add the XBGR8888 format to the checklist so the plane code can use it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Production GMA3600/3650 hardware turns out to be subtly different to the development platforms. This combined with a minor driver bug is causing the kernel to hang on these platforms. This patch does the following - turn down a couple of messages that were meant to be debug and are causing much confusion - ensure the hotplug interrupt is disabled on Cedartrail systems. - fix a bug where gtt roll mode called psbfb_sync, which tries to sync the 2D engine. On other devices it is harmless as the 2D engine is present but not in use when in gtt roll mode, on Cedartrail it causes a hang Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| * | sparc32: Add -Av8 to assembler command line.David S. Miller2012-03-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer version of binutils are more strict about specifying the correct options to enable certain classes of instructions. The sparc32 build is done for v7 in order to support sun4c systems which lack hardware integer multiply and divide instructions. So we have to pass -Av8 when building the assembler routines that use these instructions and get patched into the kernel when we find out that we have a v8 capable cpu.

That can be easily reproduced with modified tx queue entry_num to some small value e.g. 16. If mac80211 already hold local->queue_stop_reason_lock, then we can wait on that lock in both rt2x00queue_pause_queue() and rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock is possible that __ieee80211_wake_queue() will be performed before __ieee80211_stop_queue(), hence we stop queue and newer wake up it again. Another race condition is possible when between rt2x00queue_threshold() check and rt2x00queue_pause_queue() we will process all pending tx buffers on different cpu. This might happen if for example interrupt will be triggered on cpu performing rt2x00mac_tx(). To prevent race conditions serialize pause/unpause by queue->tx_lock.

Dummy tun_release() is required for sk_release_kernel() ---> sock_release() ---> sock->ops->release() call. TUN was designed to destroy it's socket on network namesapce shutdown. But this will never happen for persistent device, because it's socket holds network namespace. This patch removes of holding network namespace by TUN socket and replaces it by creating socket in init_net and then changing it's net it to desired one. On shutdown socket is moved back to init_net prior to final put. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Simon Kirby discovered a successful connection was delayed by 20 seconds before being responsive. In my tests, I discovered that xmit frames were lost, and needed ~4 retransmits and a socket dst rebuild before being really sent. In case of syncookie initiated connection, we use a different path to initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared. As ip_queue_xmit() now depends on inet flow being setup, fix this by copying the temp flowi4 we use in cookie_v4_check().

Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

The bug manisfested itself as a memory error reported by perf record. I ran into it with perf sched: $ perf sched rec noploop 2 noploop for 2 seconds [ perf record: Woken up 14 times to write data ] [ perf record: Captured and wrote 42.701 MB perf.data (~1865622 samples) ] Fatal: No memory to alloc tracepoints list It turned out that tracepoint_id_to_path() was reading the tracepoint id using read() but the buffer was not large enough to include the \n terminator for id with 4 digits or more. The patch fixes the problem by extending the buffer to a more reasonable size covering all possible id length include \n terminator. Note that atoll() stops at the first non digit character, thus it is not necessary to clear the buffer between each read.

The idea was that some filesystems may want their own special lockdep class for different directory inodes and calling unlock_new_inode() should not clobber one of those special classes. I believe that the added conditional, around the *negated* return value of lockdep_match_class(), caused directory inodes to be placed in the wrong lockdep class. inode_init_always() sets the i_mutex lockdep class with i_mutex_key for all inodes. If the filesystem did not change the class during inode initialization, then the conditional mentioned above was false and the directory inode was incorrectly left in the non-directory lockdep class. If the filesystem did set a special lockdep class, then the conditional mentioned above was true and that class was clobbered with i_mutex_dir_key. This patch removes the negation from the conditional so that the i_mutex lockdep class is properly set for directory inodes. Special classes are preserved and directory inodes with unmodified classes are set with i_mutex_dir_key.

Then, in some situations, a diagnostic message is printed to the console by one of the runtime suspend routines handling the sh-sci device, which causes synchronous runtime resume to be started from the device's own runtime suspend callback. This causes rpm_resume() to be run eventually, which sees the RPM_SUSPENDING status set by rpm_suspend() and waits for it to change. However, the device's runtime PM status cannot change at that point, because the routine that has set it waits for the rpm_suspend() to return. A deadlock occurs as a result. To avoid that make sci_init_single() increment the device's runtime PM usage counter, so that it cannot be suspended by driver_probe_device(). That counter has to be decremented eventually, so make sci_startup() do that before starting to actually use the device and make sci_shutdown() increment it again before returning to balance the incrementation carried out by sci_startup().
