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.

2012-03-01ARM: 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>

2012-02-29tg3: Fix tg3_get_stats64 for 5700 / 5701 devsMatt Carlson
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. When tg3_get_stats64() is called in tg3_halt(), deadlock will occur. This patch fixes the problem by separating the stat gathering code into a new tg3_get_nstats() function. tg3_get_stats64() is recoded to call this function and take tp->lock. The code that takes tp->lock in tg3_calc_crc_errors() has been removed. Function signatures have been cleaned up too.

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.

2012-02-28tcp: fix false reordering signal in tcp_shifted_skbNeal Cardwell
When tcp_shifted_skb() shifts bytes from the skb that is currently pointed to by 'highest_sack' then the increment of TCP_SKB_CB(skb)->seq implicitly advances tcp_highest_sack_seq(). This implicit advancement, combined with the recent fix to pass the correct SACKed range into tcp_sacktag_one(), caused tcp_sacktag_one() to think that the newly SACKed range was before the tcp_highest_sack_seq(), leading to a call to tcp_update_reordering() with a degree of reordering matching the size of the newly SACKed range (typically just 1 packet, which is a NOP, but potentially larger). This commit fixes this by simply calling tcp_sacktag_one() before the TCP_SKB_CB(skb)->seq advancement that can advance our notion of the highest SACKed sequence. Correspondingly, we can simplify the code a little now that tcp_shifted_skb() should update the lost_cnt_hint in all cases where skb == tp->lost_skb_hint.

In the spirit of commit 29cf7a30f8a0 ("x86/PCI: use host bridge _CRS info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by default on a board that needs it. This fixes boot failures and oopses introduced in 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci read out res"). The quirk is quite targetted (to a specific board and BIOS version) for two reasons: (1) to emphasize that this method of tackling the problem one quirk at a time is a little insane (2) to give BIOS vendors an opportunity to use simpler tables and allow us to return to generic behavior (whatever that happens to be) with a later BIOS update In other words, I am not at all happy with having quirks like this. But it is even worse for the kernel not to work out of the box on these machines, so...

2012-02-28Merge tag 'iommu-fixes-v3.3-rc5' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu IOMMU fixes for Linux 3.3-rc5 All the fixes are for the OMAP IOMMU driver. The first patch is the biggest one. It fixes the calls of the function omap_find_iovm_area() in the omap-iommu-debug module which expects a 'struct device' parameter since commit fabdbca instead of an omap_iommu handle. The omap-iommu-debug code still passed the handle to the function which caused a crash. The second patch fixes a NULL pointer dereference in the OMAP code and the third patch makes sure that the omap-iommu is initialized before the omap-isp driver, which relies on the iommu. The last patch is only a workaround until defered probing is implemented. * tag 'iommu-fixes-v3.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp iommu/omap: fix NULL pointer dereference iommu/omap: fix erroneous omap-iommu-debug API calls

2012-02-28watchdog: fix error in probe() of s3c2410_wdt (reset at booting)MyungJoo Ham
Probe function of s3c2410 watchdog calls request_irq before initializing required value (wdt_count). This incurs resetting watchdog counter value and watchdog-reboot during booting up. This patch addresses such an issue by calling request_irq later. Error handling in probe function and calling oder in remove function are also revised accordingly.

2012-02-28[PARISC] don't unconditionally override CROSS_COMPILE for 64 bit.James Bottomley
The user may wish to set their own value (for real cross compiles). Since the top level Makefile initialises CROSS_COMPILE to empty by default, we must check it for being empty (rather than for being defined) before we override.

2012-02-28GFS2: Read resource groups on mountSteven Whitehouse
This makes mount take slightly longer, but at the same time, the first write to the filesystem will be faster too. It also means that if there is a problem in the resource index, then we can refuse to mount rather than having to try and report that when the first write occurs. In addition, to avoid recursive locking, we hvae to take account of instances when the rindex glock may already be held when we are trying to update the rbtree of resource groups.

2012-02-28GFS2: Ensure rindex is uptodate for fallocateBob Peterson
This patch fixes a problem whereby gfs2_grow was failing and causing GFS2 to assert. The problem was that when GFS2's fallocate operation tried to acquire an "allocation" it made sure the rindex was up to date, and if not, it called gfs2_rindex_update. However, if the file being fallocated was the rindex itself, it was already locked at that point. By calling gfs2_rindex_update at an earlier point in time, we bring rindex up to date and thereby avoid trying to lock it when the "allocation" is acquired.

2012-02-28perf/hwbp: Fix a possible memory leakNamhyung Kim
If kzalloc() for TYPE_DATA failed on a given cpu, previous chunk of TYPE_INST will be leaked. Fix it. Thanks to Peter Zijlstra for suggesting this better solution. It should work as long as the initial value of the region is all 0's and that's the case of static (per-cpu) memory allocation.
