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>

2012-04-19ALSA: hda/conexant - Set up the missing docking-station pinsTakashi Iwai1-3/+25
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. (I didn't find this by using FUSE, but in reusing the function for tmpfs.)

2012-04-19KVM: lock slots_lock around device assignmentAlex Williamson1-8/+15
As pointed out by Jason Baron, when assigning a device to a guest we first set the iommu domain pointer, which enables mapping and unmapping of memory slots to the iommu. 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. Take the slots_lock around creating the iommu domain and initial mappings as well as around iommu teardown to avoid this race.

2012-04-18KVM: VMX: Fix kvm_set_shared_msr() called in preemptible contextAvi Kivity1-1/+4
kvm_set_shared_msr() may not be called in preemptible context, but vmx_set_msr() does so: BUG: using smp_processor_id() in preemptible [00000000] code: qemu-kvm/22713 caller is kvm_set_shared_msr+0x32/0xa0 [kvm] Pid: 22713, comm: qemu-kvm Not tainted 3.4.0-rc3+ #39 Call Trace: [<ffffffff8131fa82>] debug_smp_processor_id+0xe2/0x100 [<ffffffffa0328ae2>] kvm_set_shared_msr+0x32/0xa0 [kvm] [<ffffffffa03a103b>] vmx_set_msr+0x28b/0x2d0 [kvm_intel] ... Making kvm_set_shared_msr() work in preemptible is cleaner, but it's used in the fast path. Making two variants is overkill, so this patch just disables preemption around the call.

2012-04-18pch_uart: Fix dma channel unallocated issueTomoya MORINAGA1-1/+3
This driver anticipates pch_uart_verify_port() is not called during installation. However, actually pch_uart_verify_port() is called during installation. As a result, memory access violation occurs like below. 0. initial value: use_dma=0 1. starup() - dma channel is not allocated because use_dma=0 2. pch_uart_verify_port() - Set use_dma=1 3. UART processing acts DMA mode because use_dma=1 - memory access violation occurs! This patch fixes the issue. Solution: Whenever pch_uart_verify_port() is called and then dma channel is not allocated, the channel should be allocated.

This call is not needed; the IRQ controller should (and does) set up interrupts correctly. set_irq_flags() isn't exported to modules, to this also fixes compilation of ehci-tegra.c as a module.
