2012-03-01x86/PCI: do not tie MSI MS-7253 use_crs quirk to BIOS versionJonathan Nieder
Carlos was getting WARNING: at drivers/pci/pci.c:118 pci_ioremap_bar+0x24/0x52() when probing his sound card, and sound did not work. After adding pci=use_crs to the kernel command line, no more trouble. Ok, we can add a quirk. dmidecode output reveals that this is an MSI MS-7253, for which we already have a quirk, but the short-sighted author tied the quirk to a single BIOS version, making it not kick in on Carlos's machine with BIOS V1.2. If a later BIOS update makes it no longer necessary to look at the _CRS info it will still be harmless, so let's stop trying to guess which versions have and don't have accurate _CRS tables.

2012-03-01sched: Ditch per cgroup task lists for load-balancingPeter Zijlstra
Per cgroup load-balance has numerous problems, chief amongst them that there is no real sane order in them. So stop pretending it makes sense and enqueue all tasks on a single list. This also allows us to more easily fix the fwd progress issue uncovered by the lock-break stuff. Rotate the list on failure to migreate and limit the total iterations to nr_running (which with releasing the lock isn't strictly accurate but close enough). Also add a filter that skips very light tasks on the first attempt around the list, this attempts to avoid shooting whole cgroups around without affecting over balance.

2012-03-01memblock: Fix size aligning of memblock_alloc_base_nid()Tejun Heo
memblock allocator aligns @size to @align to reduce the amount of fragmentation. Commit: 7bd0b0f0da ("memblock: Reimplement memblock allocation using reverse free area iterator") Broke it by incorrectly relocating @size aligning to memblock_find_in_range_node(). As the aligned size is not propagated back to memblock_alloc_base_nid(), the actually reserved size isn't aligned. While this increases memory use for memblock reserved array, this shouldn't cause any critical failure; however, it seems that the size aligning was hiding a use-beyond-allocation bug in sparc64 and losing the aligning causes boot failure. The underlying problem is currently being debugged but this is a proper fix in itself, it's already pretty late in -rc cycle for boot failures and reverting the change for debugging isn't difficult. Restore the size aligning moving it to memblock_alloc_base_nid(). Reported-by: Meelis Roos <mroos@linux.ee> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: David S.

2012-03-01sched/rt: Prevent idle task boostingThomas Gleixner
Idle task boosting is a nono in general. There is one exception, when PREEMPT_RT and NOHZ is active: The idle task calls get_next_timer_interrupt() and holds the timer wheel base->lock on the CPU and another CPU wants to access the timer (probably to cancel it). We can safely ignore the boosting request, as the idle CPU runs this code with interrupts disabled and will complete the lock protected section without being interrupted. So there is no real need to boost.

2012-03-01ARM: S3C24XX: Fix restart on S3C2442Heiko Stuebner
Commit b27b072791dc (ARM: 7265/1: restart: S3C24XX: use new restart hook) introduced the new restart hook also for the S3C244x cpus, but it was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was selected. Devices using the S3C2442 like the GTA02 normally don't select this CPU which leads to compilation errors like: LD .tmp_vmlinux1 arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference to `s3c2440_restart' make: *** [.tmp_vmlinux1] Error 1 Therefore move the s3c2440_restart function to s3c244x.c which is common to both cpus and also fix the naming to reflect this.

2012-03-01virtio: balloon: leak / fill balloon across S4Amit Shah
commit e562966dbaf49e7804097cd991e5d3a8934fc148 added support for S4 to the balloon driver. The freeze function did nothing to free the pages, since reclaiming the pages from the host to immediately give them back (if S4 was successful) seemed wasteful. Also, if S4 wasn't successful, the guest would have to re-fill the balloon. On restore, the pages were supposed to be marked freed and the free page counters were incremented to reflect the balloon was totally deflated. However, this wasn't done right. The pages that were earlier taken away from the guest during a balloon inflation operation were just shown as used pages after a successful restore from S4. Just a fancy way of leaking lots of memory. Instead of trying that, just leak the balloon on freeze and fill it on restore/thaw paths. This works properly now. The optimisation to not leak can be added later on after a bit of refactoring of the code. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-02-29OMAPDSS: APPLY: make ovl_enable/disable synchronousTomi Valkeinen
ovl->enable/disable are meant to be synchronous so that they can handle the configuration of fifo sizes. The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700 and bcm5701 devices. However, functions that call tg3_halt() have already acquired tp->lock.

Recent commit "mwifiex: clear previous security setting during association" fixes association failure problems observed in some corner cases by clearing previous security setting before each association. We should reset encryption mode flag as well. This patch takes care of it. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2012-02-29carl9170: fix frame delivery if sta is in powersave modeChristian Lamparter
Nicolas Cavallari discovered that carl9170 has some serious problems delivering data to sleeping stations. It turns out that the driver was not honoring two important flags (IEEE80211_TX_CTL_POLL_RESPONSE and IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on frames that should be sent although the receiving station is still in powersave mode.

2012-02-29carl9170: Fix memory accounting when sta is in power-save mode.Nicolas Cavallari
On Access Point mode, when transmitting a packet, if the destination station is in powersave mode, we abort transmitting the packet to the device queue, but we do not reclaim the allocated memory. Given enough packets, we can go in a state where there is no packet on the device queue, but we think the device has no memory left, so no packet gets transmitted, connections breaks and the AP stops working. This undo the allocation done in the TX path when the station is in power-save mode.

2012-02-29ALSA: hda - Add a fake mute featureTakashi Iwai
Some codecs don't supply the mute amp-capabilities although the lowest volume gives the mute. It'd be handy if the parser provides the mute mixers in such a case. This patch adds an extension amp-cap bit (which is used only in the driver) to represent the min volume = mute state. Also modified the amp cache code to support the fake mute feature when this bit is set but the real mute bit is unset. In addition, conexant cx5051 parser uses this new feature to implement the missing mute controls.

Commit dcfb748422 ([WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in seconds) fixed SETTIMEOUT ioctl to use seconds as a parameter instead of some hardware-specific "period", but missed to apply similar changes to GETTIMEOUT, so it still returns "period" value. Let's fix it! Also, while at it, make SETTIMEOUT ioctl return real timeout value as it should do according to the documentation.
