2012-02-09mm: fix UP THP spin_is_locked BUGsHugh Dickins
Fix CONFIG_TRANSPARENT_HUGEPAGE=y CONFIG_SMP=n CONFIG_DEBUG_VM=y CONFIG_DEBUG_SPINLOCK=n kernel: spin_is_locked() is then always false, and so triggers some BUGs in Transparent HugePage codepaths. asm-generic/bug.h mentions this problem, and provides a WARN_ON_SMP(x); but being too lazy to add VM_BUG_ON_SMP, BUG_ON_SMP, WARN_ON_SMP_ONCE, VM_WARN_ON_SMP_ONCE, just test NR_CPUS != 1 in the existing VM_BUG_ONs.

2012-02-09drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmaxAxel Lin
In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and pltfm->als_vmax is 0. This does not make sense. I think what we want here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV. Both als_vmin and als_vmax local variables will be set to pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also remove a redundant assignment for als_vmin and als_vmax in this patch.

2012-02-09mm: compaction: check for overlapping nodes during isolation for migrationMel Gorman
When isolating pages for migration, migration starts at the start of a zone while the free scanner starts at the end of the zone. Migration avoids entering a new zone by never going beyond the free scanned. Unfortunately, in very rare cases nodes can overlap. When this happens, migration isolates pages without the LRU lock held, corrupting lists which will trigger errors in reclaim or during page free such as in the following oops BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffff810f795c>] free_pcppages_bulk+0xcc/0x450 PGD 1dda554067 PUD 1e1cb58067 PMD 0 Oops: 0000 [#1] SMP CPU 37 Pid: 17088, comm: memcg_process_s Tainted: G X RIP: free_pcppages_bulk+0xcc/0x450 Process memcg_process_s (pid: 17088, threadinfo ffff881c2926e000, task ffff881c2926c0c0) Call Trace: free_hot_cold_page+0x17e/0x1f0 __pagevec_free+0x90/0xb0 release_pages+0x22a/0x260 pagevec_lru_move_fn+0xf3/0x110 putback_lru_page+0x66/0xe0 unmap_and_move+0x156/0x180 migrate_pages+0x9e/0x1b0 compact_zone+0x1f3/0x2f0 compact_zone_order+0xa2/0xe0 try_to_compact_pages+0xdf/0x110 __alloc_pages_direct_compact+0xee/0x1c0 __alloc_pages_slowpath+0x370/0x830 __alloc_pages_nodemask+0x1b1/0x1c0 alloc_pages_vma+0x9b/0x160 do_huge_pmd_anonymous_page+0x160/0x270 do_page_fault+0x207/0x4c0 page_fault+0x25/0x30 The "X" in the taint flag means that external modules were loaded but but is unrelated to the bug triggering.

This was discovered in a 3.0-based kernel but it affects 3.1.x, 3.2.x and current mainline.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus The only particularly remarkable change here is the one for handling of the Android suspend ignore code for idle_bias_off CODECs. That one is actually a regression fix as some of the new power savings that have been introduced confused the suspend ignore code, making devices that are active for non-audio reasons look like they are idle causing them to be suspended instead of being kept active.

2012-02-07target: Fix target_submit_cmd() exception handlingNicholas Bellinger
This patch fixes a bug in target_submit_cmd() where the failure path for transport_generic_allocate_tasks() made a direct call to transport_send_check_condition_and_sense() and not calling the final target_put_sess_cmd() release callback. For transport_generic_allocate_tasks() failures, use the proper call to transport_generic_request_failure() to handle kref_put() along with potential internal queue full response processing. It also makes transport_lookup_cmd_lun() failures in target_submit_cmd() use transport_send_check_condition_and_sense() and target_put_sess_cmd() directly to avoid se_cmd->se_dev reference in transport_generic_request_failure() handling. Finally it drops the out_check_cond: label and use direct reference for allocate task failures, and per-se_device queue_full handling is currently not supported for transport_lookup_cmd_lun() failure descriptors due to se_device dependency.

On BOT I can't send the SENSE response back, instead I can only reply that an error occured. The next thing happens is a REQUEST_SENSE request with 18 bytes length. Since the check here is more than 18 bytes I have to NACK that request as well. This is not really required: We check for some additional room, but we never use it. The additional length is set to 0xa so the total length is 0xa + 8 = 18 which is fine with my 18 bytes.

2012-02-06exec: fix use-after-free bug in setup_new_exec()Heiko Carstens
Setting the task name is done within setup_new_exec() by accessing bprm->filename. However this happens after flush_old_exec(). This may result in a use after free bug, flush_old_exec() may "complete" vfork_done, which will wake up the parent which in turn may free the passed in filename. To fix this add a new tcomm field in struct linux_binprm which contains the now early generated task name until it is used.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Power management fixes for 3.3-rc3 Three power management regression fixes, one for a recent regression introcuded by the freezer changes during the 3.3 merge window and two for regressions in cpuidle (resulting from PM QoS changes) and in the hibernate user space interface, both introduced during the 3.2 development cycle. They include: * Two hibernate (s2disk) regression fixes from Srivatsa S. Bhat (for regressions introduced during the 3.3 merge window and during the 3.2 development cycle). * A cpuidle fix from Venki Pallipadi for a regression resulting from PM QoS changes during the 3.2 development cycle causing cpuidle to work incorrectly for CONFIG_PM unset. * tag 'pm-fixes-for-3.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / QoS: CPU C-state breakage with PM Qos change PM / Freezer: Thaw only kernel threads if freezing of kernel threads fails PM / Hibernate: Thaw kernel threads in SNAPSHOT_CREATE_IMAGE ioctl path
2012-02-04PM / QoS: CPU C-state breakage with PM Qos changeVenkatesh Pallipadi
Looks like change "PM QoS: Move and rename the implementation files" merged during the 3.2 development cycle made PM QoS depend on CONFIG_PM which depends on (PM_SLEEP || PM_RUNTIME). That breaks CPU C-states with kernels not having these CONFIGs, causing CPUs to spend time in Polling loop idle instead of going into deep C-states, consuming way way more power. This is with either acpi idle or intel idle enabled. Either CONFIG_PM should be enabled with any pm_qos users or the !CONFIG_PM pm_qos_request() should return sane defaults not to break the existing users. Here's is the patch for the latter option.

2012-02-04PM / Freezer: Thaw only kernel threads if freezing of kernel threads failsSrivatsa S. Bhat
If freezing of kernel threads fails, we are expected to automatically thaw tasks in the error recovery path. However, at times, we encounter situations in which we would like the automatic error recovery path to thaw only the kernel threads, because we want to be able to do some more cleanup before we thaw userspace. Something like: error = freeze_kernel_threads(); if (error) { /* Do some cleanup */ /* Only then thaw userspace tasks*/ thaw_processes(); } An example of such a situation is where we freeze/thaw filesystems during suspend/hibernation. There, if freezing of kernel threads fails, we would like to thaw the frozen filesystems before thawing the userspace tasks. So, modify freeze_kernel_threads() to thaw only kernel threads in case of freezing failure. And change suspend_freeze_processes() accordingly. (At the same time, let us also get rid of the rather cryptic usage of the conditional operator (:?) in that function.) [rjw: In fact, this patch fixes a regression introduced during the 3.3 merge window, because without it thaw_processes() may be called before swsusp_free() in some situations and that may lead to massive memory allocation failures.] Signed-off-by: Srivatsa S.
