Commit 30765b92 ("slab, lockdep: Annotate the locks before using them") moves the init_lock_keys() call from after g_cpucache_up = FULL, to before it. And overlooks the fact that init_node_lock_keys() tests for it and ignores everything !FULL. Introduce a LATE stage and change the lockdep test to be <LATE.

People with old AMD chips are getting hung boots, because commit bcb80e53 ("x86, microcode, AMD: Add microcode revision to /proc/cpuinfo") moved the microcode detection too early into "early_init_amd()". At that point we are *so* early in the booth that the exception tables haven't even been set up yet, so the whole rdmsr_safe(MSR_AMD64_PATCH_LEVEL, &c->microcode, &dummy); doesn't actually work: if the rdmsr does a GP fault (due to non-existant MSR register on older CPU's), we can't fix it up yet, and the boot fails. Fix it by simply moving the code to a slightly later point in the boot (init_amd() instead of early_init_amd()), since the kernel itself doesn't even really care about the microcode patchlevel at this point (or really ever: it's made available to user space in /proc/cpuinfo, and updated if you do a microcode load).

The idea behind commit d91ee586 ("cpuidle: replace xen access to x86 pm_idle and default_idle") was to have one call - disable_cpuidle() which would make pm_idle not be molested by other code. It disallows cpuidle_idle_call to be set to pm_idle (which is excellent). But in the select_idle_routine() and idle_setup(), the pm_idle can still be set to either: amd_e400_idle, mwait_idle or default_idle. This depends on some CPU flags (MWAIT) and in AMD case on the type of CPU. In case of mwait_idle we can hit some instances where the hypervisor (Amazon EC2 specifically) sets the MWAIT and we get: Brought up 2 CPUs invalid opcode: 0000 [#1] SMP Pid: 0, comm: swapper Not tainted 3.1.0-0.rc6.git0.3.fc16.x86_64 #1 RIP: e030:[<ffffffff81015d1d>] [<ffffffff81015d1d>] mwait_idle+0x6f/0xb4 ... Call Trace: [<ffffffff8100e2ed>] cpu_idle+0xae/0xe8 [<ffffffff8149ee78>] cpu_bringup_and_idle+0xe/0x10 RIP [<ffffffff81015d1d>] mwait_idle+0x6f/0xb4 RSP <ffff8801d28ddf10> In the case of amd_e400_idle we don't get so spectacular crashes, but we do end up making an MSR which is trapped in the hypervisor, and then follow it up with a yield hypercall. Meaning we end up going to hypervisor twice instead of just once. The previous behavior before v3.0 was that pm_idle was set to default_idle regardless of select_idle_routine/idle_setup. We want to do that, but only for one specific case: Xen. This patch does that.

In irq_wait_for_interrupt(), the should_stop member is verified before setting the task's state to TASK_INTERRUPTIBLE and calling schedule(). In case kthread_stop sets should_stop and wakes up the process after should_stop is checked by the irq thread but before the task's state is changed, the irq thread might never exit: kthread_stop irq_wait_for_interrupt ------------ ---------------------- ... ... while (!kthread_should_stop()) { kthread->should_stop = 1; wake_up_process(k); wait_for_completion(&kthread->exited); ... set_current_state(TASK_INTERRUPTIBLE); ... schedule(); } Fix this by checking if the thread should stop after modifying the task's state.

There are two issues in vmw_kms_update_layout_ioctl(). First, the for loop forgets to index rects and only checks the first element. Second, there is a potential integer overflow if userspace passes in a large arg->num_outputs. The call to kzalloc() would allocate a small buffer, leading to out-of-bounds read.

Disabling the CRTC by setting its framebuffer to NULL, as used by drm_framebuffer_cleanup(), was failing to pass the current framebuffer to the crtc_func->disable callback. This is because of the dance within drm_crtc_helper_set_config to pass the new_fb (NULL in this case) to the drm_crtc_helper_set_mode with the currently attached fb as a parameter. drm_crtc_helper_set_mode treats this as a no-op and the encoder is still enabled. And so the current fb is forgotten before the call to drm_helper_disable_unused_functions. This patch treats disabling the CRTC as a simple special case rather than adding further complexity into the configuration logic. This fixes a pin-leak of the fb bo on Xserver close.

RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.

Sarah Sharp authored
This reverts commit df711fc9. The commit added a reset-on-resume quirk because the NEC chipset stopped responding to commands about 30 minutes after a system resume from suspend. We thought it was a chipset issue, but it turns out that the xHCI driver was zeroing out the link TRB after a successful context restore during resume. The host controller would fall off the command ring sometime later, causing it to not respond to new commands. The link TRB issue has been fixed with commit 158886cd "xHCI: fix bug in xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's not necessary. Commit df711fc9 was marked for stable trees back to 2.6.37, but according to my mail, it has not made it into Linus' tree or the stable trees yet.

Andiry Xu authored
When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

Commit 4a54c8c1 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.

If a driver wants to do command mode IO while CIO is doing online path verification we ignore this request and provide a fake irb when we are done and the driver can do IO again. For transport mode IO we have no such mechanism, giving the driver no other chance then to retry the action until we are done. This is not very reliable.
