2012-04-20mmc: cd-gpio: Include header to pickup exported symbol prototypesH Hartley Sweeten1-0/+1
Include the linux/mmc/cd-gpio.h header to pickup the prototypes for the two exported symbols. This quiets the sparse warnings: warning: symbol 'mmc_cd_gpio_request' was not declared. Should it be static? warning: symbol 'mmc_cd_gpio_free' was not declared. Should it be static?

2012-04-20mmc: sdhci: refine non-removable card checking for card detectionDaniel Drake1-1/+1
Commit c79396c191bc19 ("mmc: sdhci: prevent card detection activity for non-removable cards") disables card detection where the cards are marked as non-removable. This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.

When dw_mci_pre_dma_transfer returns failure in some reasons, dw_mci_submit_data will prepare to switch the PIO mode from DMA. After switching to PIO mode, DMA(IDMAC in particular) is still enabled. This makes the corruption in handling interrupt and the driver lock-up.

MMC bus is using legacy suspend/resume method, which is not compatible if runtime pm callbacks are used. In this scenario, MMC bus suspend/resume callbacks cannot be called when system entering S3.

2012-04-20mmc: fixes for eMMC v4.5 discard operationAdrian Hunter2-4/+5
eMMC v4.5 discard operation is significantly different from the existing trim operation because it is not guaranteed to work with the new sanitize operation. Consequently mmc_can_trim() is separated from mmc_can_discard(). Also the new discard operation does not result in the sectors being set to all-zeros, so discard_zeroes_data must not be set. In addition, the new discard has the same timeout as trim, but from v4.5 trim is defined to use the hc timeout. The timeout calculation is adjusted accordingly. Fixes apply to linux 3.2 on.

2012-04-20Revert "ACPI: ignore FADT reset-reg-sup flag"Linus Torvalds2-2/+4
This reverts commit cf450136bfde77c7f95065c91bffded4aa7fa731. It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte: "On reboot it shuts down as normal. The last lines displayed are: >Unmounting temporary filesystems.. [OK] >Deactivating swap... [OK] >Unmounting local filesystems... [OK] >Will now restart > Restarting system Then I hear it accessing the cd-drive, but then it's being stuck." Jörg bisected the regression to this commit. That commit fixes another machine (see https://bugzilla.kernel.org/show_bug.cgi?id=11533 for details) that has a BIOS bug and doesn't support ACPI reset. However, at least one of those other reporters no longer even has the machine in question, and had a different workaround to begin with. Besides, it clearly was a buggy BIOS. Let's not break the correct case to fix that case.

2012-04-20memblock: memblock should be able to handle zero length operationsTejun Heo1-1/+6
Commit 24aa07882b ("memblock, x86: Replace memblock_x86_reserve/ free_range() with generic ones") replaced x86 specific memblock operations with the generic ones; unfortunately, it lost zero length operation handling in the process making the kernel panic if somebody tries to reserve zero length area. There isn't much to be gained by being cranky to zero length operations and panicking is almost the worst response. Drop the BUG_ON() in memblock_reserve() and update memblock_add_region/isolate_range() so that all zero length operations are handled as noops.

2012-04-19xen/xenbus: Add quirk to deal with misconfigured backends.Konrad Rzeszutek Wilk1-16/+53
A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" CC: stable@kernel.org Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> [v3: Split delay in non-essential (30 seconds) and essential devices per Ian and Stefano suggestion] [v4: Added comments per Stefano suggestion] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

ThinkPad 410,420,510,520 and X201 with cx50585 & co chips have the docking-station ports, but BIOS doesn't initialize for these pins. Thus, like the former X200, we need to set up the pins manually in the driver. The odd part is that the same PCI SSID is used for X200 and T400, thus we need to prepare individual fixup tables for cx5051 and others.

My 9ce70c0240d0 "memcg: fix deadlock by inverting lrucare nesting" put a nasty little bug into v3.3's version of mem_cgroup_replace_page_cache(), sometimes used for FUSE. Replacing __mem_cgroup_commit_charge_lrucare() by __mem_cgroup_commit_charge(), I used the "pc" pointer set up earlier: but it's for oldpage, and needs now to be for newpage. Once oldpage was freed, its PageCgroupUsed bit (cleared above but set again here) caused "Bad page state" messages - and perhaps worse, being missed from newpage.

This leaves a window where this path is enabled, but we haven't synchronized the iommu mappings to the existing memory slots. Thus a slot being removed at that point could send us down unexpected code paths removing non-existent pinnings and iommu mappings.

2012-04-18xz: Enable BCJ filters on SPARC and 32-bit x86Lasse Collin1-2/+2
The BCJ filters were meant to be enabled already on these archs, but the xz_wrap.sh script was buggy. Enabling the filters should give smaller kernel images. xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect the architecture. That way it doesn't need to care about the subarchs (like i386 vs. x86_64) since the BCJ filters don't care either.

2012-04-18EHCI: always clear the STS_FLR status bitAlan Stern1-1/+6
This patch (as1544) fixes a problem affecting some EHCI controllers. They can generate interrupts whenever the STS_FLR status bit is turned on, even though that bit is masked out in the Interrupt Enable register. Since the driver doesn't use STS_FLR anyway, the patch changes the interrupt routine to clear that bit whenever it is set, rather than leaving it alone.

2012-04-18hwmon: fam15h_power: fix bogus values with current BIOSesAndre Przywara1-0/+39
Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.

2012-04-18Revert "ACPI: Make ACPI interrupt threaded"Thomas Gleixner1-2/+1
This reverts commit 6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d. Paul bisected this regression. The conversion was done blindly and is wrong, as it does not provide a primary handler to disable the level type irq on the device level. Neither does it set the IRQF_ONESHOT flag which handles that at the irq line level. This can't be done as the interrupt might be shared, though we might extend the core to force it. So an interrupt on this line will wake up the thread, but immediately unmask the irq after that. Due to the interrupt being level type the hardware interrupt is raised over and over and prevents the irq thread from handling it. Fail. request_irq() unfortunately does not refuse such a request and the patch was obviously never tested with real interrupts.
