git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull xen updates from Konrad Rzeszutek Wilk: "which has three neat features: - PV multiconsole support, so that there can be hvc1, hvc2, etc; This can be used in HVM and in PV mode. - P-state and C-state power management driver that uploads said power management data to the hypervisor. It also inhibits cpufreq scaling drivers to load so that only the hypervisor can make power management decisions - fixing a weird perf bug. There is one thing in the Kconfig that you won't like: "default y if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by default is off). I've a fix to convert that boolean expression into "default m" which I am going to post after the cpufreq git pull - as the two patches to make this work depend on a fix in Dave Jones's tree. - Function Level Reset (FLR) support in the Xen PCI backend.

2012-03-22Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds1-0/+16
Pull drm main changes from Dave Airlie: "This is the main drm pull request, I'm probably going to send two more smaller ones, will explain below. This contains a patch that is also in the fbdev tree, but it should be the same patch, it added an API for hot unplugging framebuffer devices, and I need that API for a new driver. It also contains some changes to the i2c tree which Jean has acked, and one change to moorestown platform stuff in x86. Highlights: - new drivers: UDL driver for USB displaylink devices, kms only, should support correct hotplug operations. - core: i2c speedups + better hotplug support, EDID overriding via firmware interface - allows user to load a firmware for a broken monitor/kvm from userspace, it even has documentation for it. - exynos: new HDMI audio + hdmi 1.4 + virtual output driver - gma500: code cleanup - radeon: cleanups, CS optimisations, streamout support and pageflip fix - nouveau: NVD9 displayport support + more reclocking work - i915: re-enabling GMBUS, finish gpu patch (might help hibernation who knows), missed irq fixes, stencil tiling fixes, interlaced support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB, semaphore fixes As well as the usual bunch of cleanups and fixes all over the place. I've got two things I'd like to merge a bit later: a) AMD support for all their new radeonhd 7000 series GPU and APUs. AMD dropped this a bit late due to insane internal review processes, (please AMD just follow Intel and let open source guys ship stuff early) however I don't want to penalise people who own this hardware (since its been on sale for 3-4 months and GPU hw doesn't exactly have a lifetime in years) and consign them to using closed drivers for longer than necessary. The changes are well contained and just plug into the driver new gpu functionality so they should be fairly regression proof. I just want to give them a bit of a run on the hw AMD kindly sent me. b) drm prime/dma-buf interface code. This is just infrastructure code to expose the dma-buf stuff to drm drivers and to userspace. I'm not planning on pushing any driver support in this cycle (except maybe exynos), but I'd like to get the infrastructure code in so for the next cycle I can start getting the driver support into the individual drivers. We have started driver support for i915, nouveau and udl along with I think exynos and omap in staging. However this code relies on the dma-buf tree being pulled into your tree first since it needs the latest interfaces from that tree. I'll push to get that tree sent asap. (oh and any warnings you see in i915 are gcc's fault from what anyone can see)."

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull updates of sound stuff from Takashi Iwai: "Here is the first big update chunk of sound stuff for 3.4-rc1. In the common sound infrastructure, there are a few changes for dynamic PCM support (used in ASoC) and a few clean-ups. Majority of changes are found, as usual, in HD-audio and ASoC. Some highlights of HD-audio changes: - All the long-standing static quirk codes for Realtek codec were finally removed by fixing and extending the Realtek auto-parser. - The mute-LED control is standardized over all HD-audio codec drivers using the extended vmaster hook. - The vmaster slave mixer elements are initialized to 0dB as default so that the user won't be annoyed by the silent output after updates, e.g. due to the additions of new elements. - Other many fix-ups for the misc HD-audio devices. In the ASoC side, this is a very active release, including a quite a few framework enhancements. Some highlights: - Support for widgets not associated with a CODEC, an important part of the dynamic PCM framework. - A library factoring out the common code shared by dmaengine based DMA drivers contributed by Lars-Peter Clausen. This will save a lot of code and make it much easier to deploy enhancements to dmaengine. - Support for binary controls, used for providing runtime configuration of algorithm coefficients. - A new DAPM widget type for regulator supplies allowing drivers for devices that can power down unused supplies while active to do without any per-driver code. - DAPM widgets for DAIs, initially giving a speed boost for playback startup and shutdown and also the basis for CODEC<->CODEC DAI link support. - Support for specifying the number of significant bits on audio interfaces, useful for allowing applications to know how much effort to put into generating data for a larger sample format. - Conversion of the FSI driver used on some SH processors to DMAEngine. - Conversion of EP93xx drivers to DMAEngine. - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200. - Move audmux driver from arc/arm to sound/soc - McBSP move from arch/ to sound/ and updates Also, a few small updates and fixes for other drivers like au88x0, ymfpci, USB 6fire, USB usx2yaudio are included." * tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits) ASoC: wm8994: Provide VMID mode control and fix default sequence ASoC: wm8994: Add missing break in resume ASoC: wm_hubs: Don't actively manage LINEOUT_VMID_BUF ASoC: pxa-ssp: atomically set stream active masks ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master ASoC: Samsung: Added to support mono recording ALSA: hda - Fix build with CONFIG_PM=n ALSA: au88x0 - Avoid possible Oops at unbinding ALSA: usb-audio - Fix build error by consitification of rate list ASoC: core: Fix obscure leak of runtime array ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link() ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list ASoC: wm8996: Add 44.1kHz support ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE ASoC: mx27vis-aic32x4: Convert it to platform driver ALSA: hda - fix printing of high HDMI sample rates ALSA: ymfpci - Fix legacy registers on S3/S4 resume ALSA: control - Fixe a trailing white space error ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook() ALSA: hda - Add "Mute-LED Mode" enum control ...

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc merge from Benjamin Herrenschmidt: "Here's the powerpc batch for this merge window. It is going to be a bit more nasty than usual as in touching things outside of arch/powerpc mostly due to the big iSeriesectomy :-) We finally got rid of the bugger (legacy iSeries support) which was a PITA to maintain and that nobody really used anymore. Here are some of the highlights: - Legacy iSeries is gone. Thanks Stephen ! There's still some bits and pieces remaining if you do a grep -ir series arch/powerpc but they are harmless and will be removed in the next few weeks hopefully. - The 'fadump' functionality (Firmware Assisted Dump) replaces the previous (equivalent) "pHyp assisted dump"... it's a rewrite of a mechanism to get the hypervisor to do crash dumps on pSeries, the new implementation hopefully being much more reliable. Thanks Mahesh Salgaonkar. - The "EEH" code (pSeries PCI error handling & recovery) got a big spring cleaning, motivated by the need to be able to implement a new backend for it on top of some new different type of firwmare. The work isn't complete yet, but a good chunk of the cleanups is there. Note that this adds a field to struct device_node which is not very nice and which Grant objects to. I will have a patch soon that moves that to a powerpc private data structure (hopefully before rc1) and we'll improve things further later on (hopefully getting rid of the need for that pointer completely). Thanks Gavin Shan. - I dug into our exception & interrupt handling code to improve the way we do lazy interrupt handling (and make it work properly with "edge" triggered interrupt sources), and while at it found & fixed a wagon of issues in those areas, including adding support for page fault retry & fatal signals on page faults. - Your usual random batch of small fixes & updates, including a bunch of new embedded boards, both Freescale and APM based ones, etc..."

2012-03-21mm: thp: fix pmd_bad() triggering in code paths holding mmap_sem read modeAndrea Arcangeli1-0/+2
In some cases it may happen that pmd_none_or_clear_bad() is called with the mmap_sem hold in read mode. In those cases the huge page faults can allocate hugepmds under pmd_none_or_clear_bad() and that can trigger a false positive from pmd_bad() that will not like to see a pmd materializing as trans huge. It's not khugepaged causing the problem, khugepaged holds the mmap_sem in write mode (and all those sites must hold the mmap_sem in read mode to prevent pagetables to go away from under them, during code review it seems vm86 mode on 32bit kernels requires that too unless it's restricted to 1 thread per process or UP builds). The race is only with the huge pagefaults that can convert a pmd_none() into a pmd_trans_huge(). Effectively all these pmd_none_or_clear_bad() sites running with mmap_sem in read mode are somewhat speculative with the page faults, and the result is always undefined when they run simultaneously. This is probably why it wasn't common to run into this. For example if the madvise(MADV_DONTNEED) runs zap_page_range() shortly before the page fault, the hugepage will not be zapped, if the page fault runs first it will be zapped. Altering pmd_bad() not to error out if it finds hugepmds won't be enough to fix this, because zap_pmd_range would then proceed to call zap_pte_range (which would be incorrect if the pmd become a pmd_trans_huge()). The simplest way to fix this is to read the pmd in the local stack (regardless of what we read, no need of actual CPU barriers, only compiler barrier needed), and be sure it is not changing under the code that computes its value. Even if the real pmd is changing under the value we hold on the stack, we don't care. If we actually end up in zap_pte_range it means the pmd was not none already and it was not huge, and it can't become huge from under us (khugepaged locking explained above). All we need is to enforce that there is no way anymore that in a code path like below, pmd_trans_huge can be false, but pmd_none_or_clear_bad can run into a hugepmd. The overhead of a barrier() is just a compiler tweak and should not be measurable (I only added it for THP builds). I don't exclude different compiler versions may have prevented the race too by caching the value of *pmd on the stack (that hasn't been verified, but it wouldn't be impossible considering pmd_none_or_clear_bad, pmd_bad, pmd_trans_huge, pmd_none are all inlines and there's no external function called in between pmd_trans_huge and pmd_none_or_clear_bad). if (pmd_trans_huge(*pmd)) { if (next-addr != HPAGE_PMD_SIZE) { VM_BUG_ON(!rwsem_is_locked(&tlb->mm->mmap_sem)); split_huge_page_pmd(vma->vm_mm, pmd); } else if (zap_huge_pmd(tlb, vma, pmd, addr)) continue; /* fall through */ } if (pmd_none_or_clear_bad(pmd)) Because this race condition could be exercised without special privileges this was reported in CVE-2012-1179. The race was identified and fully explained by Ulrich who debugged it. I'm quoting his accurate explanation below, for reference. ====== start quote ======= mapcount 0 page_mapcount 1 kernel BUG at mm/huge_memory.c:1384! At some point prior to the panic, a "bad pmd ..." message similar to the following is logged on the console: mm/memory.c:145: bad pmd ffff8800376e1f98(80000000314000e7). The "bad pmd ..." message is logged by pmd_clear_bad() before it clears the page's PMD table entry. 143 void pmd_clear_bad(pmd_t *pmd) 144 { -> 145 pmd_ERROR(*pmd); 146 pmd_clear(pmd); 147 } After the PMD table entry has been cleared, there is an inconsistency between the actual number of PMD table entries that are mapping the page and the page's map count (_mapcount field in struct page). When the page is subsequently reclaimed, __split_huge_page() detects this inconsistency. 1381 if (mapcount != page_mapcount(page)) 1382 printk(KERN_ERR "mapcount %d page_mapcount %d\n", 1383 mapcount, page_mapcount(page)); -> 1384 BUG_ON(mapcount != page_mapcount(page)); The root cause of the problem is a race of two threads in a multithreaded process. Thread B incurs a page fault on a virtual address that has never been accessed (PMD entry is zero) while Thread A is executing an madvise() system call on a virtual address within the same 2 MB (huge page) range. virtual address space .---------------------. | | | | .-|---------------------| | | | | | |<-- B(fault) | | | 2 MB | |/////////////////////|-. huge < |/////////////////////| > A(range) page | |/////////////////////|-' | | | | | | '-|---------------------| | | | | '---------------------' - Thread A is executing an madvise(..., MADV_DONTNEED) system call on the virtual address range "A(range)" shown in the picture. sys_madvise // Acquire the semaphore in shared mode. down_read(&current->mm->mmap_sem) ... madvise_vma switch (behavior) case MADV_DONTNEED: madvise_dontneed zap_page_range unmap_vmas unmap_page_range zap_pud_range zap_pmd_range // // Assume that this huge page has never been accessed. // I.e. content of the PMD entry is zero (not mapped). // if (pmd_trans_huge(*pmd)) { // We don't get here due to the above assumption. } // // Assume that Thread B incurred a page fault and .---------> // sneaks in here as shown below. | // | if (pmd_none_or_clear_bad(pmd)) | { | if (unlikely(pmd_bad(*pmd))) | pmd_clear_bad | { | pmd_ERROR | // Log "bad pmd ..." message here. | pmd_clear | // Clear the page's PMD entry. | // Thread B incremented the map count | // in page_add_new_anon_rmap(), but | // now the page is no longer mapped | // by a PMD entry (-> inconsistency). | } | } | v - Thread B is handling a page fault on virtual address "B(fault)" shown in the picture. ... do_page_fault __do_page_fault // Acquire the semaphore in shared mode. down_read_trylock(&mm->mmap_sem) ... handle_mm_fault if (pmd_none(*pmd) && transparent_hugepage_enabled(vma)) // We get here due to the above assumption (PMD entry is zero). do_huge_pmd_anonymous_page alloc_hugepage_vma // Allocate a new transparent huge page here. ... __do_huge_pmd_anonymous_page ... spin_lock(&mm->page_table_lock) ... page_add_new_anon_rmap // Here we increment the page's map count (starts at -1). atomic_set(&page->_mapcount, 0) set_pmd_at // Here we set the page's PMD entry which will be cleared // when Thread A calls pmd_clear_bad(). ... spin_unlock(&mm->page_table_lock) The mmap_sem does not prevent the race because both threads are acquiring it in shared mode (down_read). Thread B holds the page_table_lock while the page's map count and PMD table entry are updated. However, Thread A does not synchronize on that lock. ====== end quote ======= [akpm@linux-foundation.org: checkpatch fixes] Reported-by: Ulrich Obergfell <uobergfe@redhat.com> Signed-off-by: Andrea Arcangeli <aarcange@redhat.com> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Mel Gorman <mgorman@suse.de> Cc: Hugh Dickins <hughd@google.com> Cc: Dave Jones <davej@redhat.com> Acked-by: Larry Woodman <lwoodman@redhat.com> Acked-by: Rik van Riel <riel@redhat.com> Cc: <stable@vger.kernel.org> [2.6.38+] Cc: Mark Salter <msalter@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-03-21Merge tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6Linus Torvalds74-2384/+400
Pull irq_domain support for all architectures from Grant Likely: "Generialize powerpc's irq_host as irq_domain This branch takes the PowerPC irq_host infrastructure (reverse mapping from Linux IRQ numbers to hardware irq numbering), generalizes it, renames it to irq_domain, and makes it available to all architectures. Originally the plan has been to create an all-new irq_domain implementation which addresses some of the powerpc shortcomings such as not handling 1:1 mappings well, but doing that proved to be far more difficult and invasive than generalizing the working code and refactoring it in-place. So, this branch rips out the 'new' irq_domain and replaces it with the modified powerpc version (in a fully bisectable way of course). It converts all users over to the new API and makes irq_domain selectable on any architecture. No architecture is forced to enable irq_domain, but the infrastructure is required for doing OpenFirmware style irq translations. It will even work on SPARC even though SPARC has it's own mechanism for translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x are converted too. The resulting irq_domain code is probably still too verbose and can be optimized more, but that can be done incrementally and is a task for follow-on patches." * tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6: (31 commits) dt: fix twl4030 for non-dt compile on x86 mfd: twl-core: Add IRQ_DOMAIN dependency devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc) irq_domain: Centralize definition of irq_dispose_mapping() irq_domain/mips: Allow irq_domain on MIPS irq_domain/x86: Convert x86 (embedded) to use common irq_domain ppc-6xx: fix build failure in flipper-pic.c and hlwd-pic.c irq_domain/microblaze: Convert microblaze to use irq_domains irq_domain/powerpc: Replace custom xlate functions with library functions irq_domain/powerpc: constify irq_domain_ops irq_domain/c6x: Use library of xlate functions irq_domain/c6x: constify irq_domain structures irq_domain/c6x: Convert c6x to use generic irq_domain support. irq_domain: constify irq_domain_ops irq_domain: Create common xlate functions that device drivers can use irq_domain: Remove irq_domain_add_simple() irq_domain: Remove 'new' irq_domain in favour of the ppc one mfd: twl-core.c: Fix the number of interrupts managed by twl4030 of/address: add empty static inlines for !CONFIG_OF irq_domain: Add support for base irq and hwirq in legacy mappings ...

2012-03-21fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_infoKuninori Morimoto1-3/+9
sh_mipi uses some clocks, but the method of setup depends on CPU. Current SuperH (like sh73a0) can control all of these clocks by CPG (Clock Pulse Generator). It means we can control it by clock framework only. But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS, and only sh7372 has PHYCTRL::PLLDS. But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was overwrote since the callback timing of clock setting was changed by c2658b70f06108361aa5024798f9c1bf47c73374 (fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()). To solve this issue, this patch adds extra .phyctrl. This patch adds detail explanation for unclear mipi settings and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).
