2016-03-22kvm, rt: change async pagefault code locking for PREEMPT_RTRik van Riel1-18/+19
The async pagefault wake code can run from the idle task in exception context, so everything here needs to be made non-preemptible. Conversion to a simple wait queue and raw spinlock does the trick. Signed-off-by: Rik van Riel <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>

2016-03-22KVM, pkeys: expose CPUID/CR4 to guestHuaitong Han4-6/+37
X86_FEATURE_PKU is referred to as "PKU" in the hardware documentation: CPUID.7.0.ECX[3]:PKU. X86_FEATURE_OSPKE is software support for pkeys, enumerated with CPUID.7.0.ECX[4]:OSPKE, and it reflects the setting of CR4.PKE(bit 22). This patch disables CPUID:PKU without ept, because pkeys is not yet implemented for shadow paging.

Protection keys define a new 4-bit protection key field (PKEY) in bits 62:59 of leaf entries of the page tables, the PKEY is an index to PKRU register(16 domains), every domain has 2 bits(write disable bit, access disable bit).

2016-03-22KVM, pkeys: save/restore PKRU when guest/host switchesXiao Guangrong1-0/+23
Currently XSAVE state of host is not restored after VM-exit and PKRU is managed by XSAVE so the PKRU from guest is still controlling the memory access even if the CPU is running the code of host. This is not safe as KVM needs to access the memory of userspace (e,g QEMU) to do some emulation. So we save/restore PKRU when guest/host switches.

2016-03-22KVM: PPC: Create a virtual-mode only TCE table handlersAlexey Kardashevskiy3-7/+57
Upcoming in-kernel VFIO acceleration needs different handling in real and virtual modes which makes it hard to support both modes in the same handler. This creates a copy of kvmppc_rm_h_stuff_tce and kvmppc_rm_h_put_tce in addition to the existing kvmppc_rm_h_put_tce_indirect. This also fixes linker breakage when only PR KVM was selected (leaving HV KVM off): the kvmppc_h_put_tce/kvmppc_h_stuff_tce functions would not compile at all and the linked would fail.

Pull MMC updates from Ulf Hansson: "MMC core: - Fix ABI regression of MMC BLK ioctl - Remove the unused MMC_DATA_STREAM flag - Enable asynchronous system PM for the host device - Minor fixes and clean-ups SDHCI host: Throughout the years, the numbers of SDHCI variants have increased and so has also the numbers of SDHCI callbacks/quirks. The purpose of these callbacks/quirks were to enable SDHCI to deal with variant specific requirements, but unfortunate this method didn't scale. Instead we have ended up with a mess. Not only did the code become suboptimal but also highly fragile. Lately many discussions of how to move forward with SDHCI has taken place at the MMC mailing list. Step by step, we aim to turn SDHCI's common code into a set of library functions. This will enable for optimizations and allow some of the existing callbacks and quirks to be removed, which also should help to make the code less fragile. Therefore I am also really pleased to announce that Adrian Hunter (Intel) has volunteered to step in as the maintainer for SDHCI. Future wise, I hope the community around SDHCI will continue to grow and that this release cycle can be the starting point of moving SDHCI into a better shape. As a matter of fact, already in this cycle the re-factoring has begun, but of course there are also fixes and new features included. Some highlights: - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP - sdhci-acpi: Add support for QCOM controllers - sdhci-pic32: Add new SDHCI variant for PIC32MZDA Other hosts: - atmel-mci: Fix a NULL pointer dereference - mediatek: Add SD write-protect support - mmc_spi: Fix card detect in GPIO case - tmio/sdhi: Add r8a7795 support - tmio/sdhi: Some fixes and clean-ups - dw_mmc: Add HW reset support - dw_mmc: Some fixes and clean-ups - sunxi: Add support for MMC DDR52 mode" * tag 'mmc-v4.6' of git://git.linaro.org/people/ulf.hansson/mmc: (123 commits) mmc: sdhci-of-at91: fix wake-up issue when using runtime pm mmc: sdhci-pci: Do not set DMA mask in enable_dma() mmc: sdhci-acpi: Remove enable_dma() hook mmc: sdhci: Set DMA mask when adding host mmc: block: fix ABI regression of mmc_blk_ioctl mmc: atmel-mci: Check pdata for NULL before dereferencing it at DMA config mmc: core: remove redundant memset of sdio_read_cccr mmc: core: remove redundant memset of mmc_decode_cid mmc: of_mmc_spi: fix unused warning mmc: sdhci-of-arasan: add phy support for sdhci-of-arasan mmc: sdhci-of-arasan: fix missing sdhci_pltfm_free for err handling mmc: sdhci-of-arasan: remove disable clk_ahb from sdhci_arasan_resume Documentation: bindings: add description of phy for sdhci-of-arasan mmc: sdhci: Fix override of timeout clk wrt max_busy_timeout mmc: mmci: Remove unnecessary header file mmc: sdhci-acpi: add QCOM controllers mmc: tegra: implement memcomp pad calibration mmc: mediatek: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch mmc: mediatek: Change signal voltage error to dev_dbg() mmc: sh_mmcif, tmio: Use ARCH_RENESAS ...

2016-03-21IB/ipoib: Allow mcast packets from other VFsEli Cohen1-7/+20
With SRIOV enabled, two VFs on the same HCA which have the same port LID and may have the same QP number. To enable receiving multicasts from such VFs, further qualify the check: ignore the receive only if, in addition, the packet source gid equals the receiving VF's source gid.

2016-03-21IB/mlx5: Implement callbacks for manipulating VFsEli Cohen6-2/+223
Implement the IB defined callbacks used to manipulate the policy for the link state, set GUIDs or get statistics information. This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.
