2012-03-02perf/x86/kvm: Fix Host-Only/Guest-Only counting with SVM disabledJoerg Roedel
It turned out that a performance counter on AMD does not count at all when the GO or HO bit is set in the control register and SVM is disabled in EFER. This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.

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.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: Gadget: changes for 3.4 This merge is rather big. Here's what it contains: For am5536udc we have just simple coding style fixes. Nothing that has any potential to cause any issues going forward. With mv_udc, there's only one single change removing an unneeded NULL check. at91_udc also only saw a single change this merge window, and that's only removing a duplicated header. The Renesas controller has a few more involved changes. Support for SUDMAC was added, there's now a special handling of IRQ resources for when the IRQ line is shared between Renesas controller and SUDMAC, we also had a bug fix where Renesas controller would sleep in atomic context while doing DMA transfers from a tasklet. There were also a set of minor cleanups. The FSL UDC also had a scheduling in atomic context bug fix, but that's all. Thanks to Sebastian, the dummy_hcd now works better than ever with support for scatterlists and streams. Sebastian also added SuperSpeed descriptors to the serial gadgets. The highlight on this merge is the addition of a generic API for mapping and unmapping usb_requests. This will avoid code duplication on all UDC controllers and also kills all the defines for DMA_ADDR_INVALID which UDC controllers sprinkled around. A few of the UDC controllers were already converted to use this new API. Conflicts: drivers/usb/dwc3/gadget.c

In summary we have a patch making modules behave better, there's a fix on debugfs' error path, a small change removing an unnecessary pm_runtime call on musb_shutdown() and a fix to relesect the endpoint in Interrupt context. This last patch is needed because we must drop musb's lock when calling request->complete() and that could cause problems if another thread queues a request and ends up changing MUSB_INDEX register.

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.

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>

The perf probe command allows kprobe to be inserted at any offset from a function start, which results in adding kprobes to unintended location. Example: perf probe do_fork+10000 is allowed even though size of do_fork is ~904. This patch will ensure probe addition fails when the offset specified is greater than size of the function.

2012-02-29perf evlist: Return first evsel for non-sample event on old kernelNamhyung Kim
On old kernels that don't support sample_id_all feature, perf_evlist__id2evsel() returns NULL for non-sampling events. This breaks perf top when multiple events are given on command line. Fix it by using first evsel in the evlist. This will also prevent getting the same (potential) problem in such new tool/ old kernel combo.

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.
