drivers/clocksource/moxart: Add Aspeed support

2016-06-03T20:51:35+00:00

The Aspeed SoC has timer IP with a very similar register layout to the moxart timer. This patch adds support for the fourth and fifth gen aspeed SoCs, and has been tested on the ast2400 and ast2500. Signed-off-by: Joel Stanley

drivers/clocksource/moxart: Use struct to hold state

2016-06-03T20:51:35+00:00

Add a struct moxart_timer to hold the driver state, including the irqaction and struct clock_event_device. Most importantly this holds values for enabling and disabling the timer, so future support can be added for devices that use different bits for enable/disable. In preparation for future hardware support we add a MOXART prefix to the existing values. Signed-off-by: Joel Stanley

drivers/clocksouree/moxart: Add kbuild symbol

2016-06-03T20:51:34+00:00

Add a Kconfig entry for this driver so other SoCs can select it. This updates the moxart Kconfig in order to select the symbol. Signed-off-by: Joel Stanley

clocksource/drivers/tango-xtal: Fix boot hang due to incorrect test

2016-04-22T07:22:37+00:00

Commit 0881841f7e78 introduced a regression by inverting a test check after calling clocksource_mmio_init(). That results on the system to hang at boot time. Fix it by inverting the test again. Fixes: 0881841f7e78 ("Replace code by clocksource_mmio_init") Reported-by: Marc Gonzalez Signed-off-by: Daniel Lezcano

clocksource/drivers/pistachio: Correct output format of PTR_ERR()

2016-03-23T11:30:40+00:00

Use signed integer output in the pr_err() string format, here PTR_ERR() value is negative and it should be reported in human readable way.

Pull KVM updates from Paolo Bonzini: "One of the largest releases for KVM... Hardly any generic changes, but lots of architecture-specific updates. ARM: - VHE support so that we can run the kernel at EL2 on ARMv8.1 systems - PMU support for guests - 32bit world switch rewritten in C - various optimizations to the vgic save/restore code. PPC: - enabled KVM-VFIO integration ("VFIO device") - optimizations to speed up IPIs between vcpus - in-kernel handling of IOMMU hypercalls - support for dynamic DMA windows (DDW). s390: - provide the floating point registers via sync regs; - separated instruction vs. data accesses - dirty log improvements for huge guests - bugfixes and documentation improvements. x86: - Hyper-V VMBus hypercall userspace exit - alternative implementation of lowest-priority interrupts using vector hashing (for better VT-d posted interrupt support) - fixed guest debugging with nested virtualizations - improved interrupt tracking in the in-kernel IOAPIC - generic infrastructure for tracking writes to guest memory - currently its only use is to speedup the legacy shadow paging (pre-EPT) case, but in the future it will be used for virtual GPUs as well - much cleanup (LAPIC, kvmclock, MMU, PIT), including ubsan fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (217 commits) KVM: x86: remove eager_fpu field of struct kvm_vcpu_arch KVM: x86: disable MPX if host did not enable MPX XSAVE features arm64: KVM: vgic-v3: Only wipe LRs on vcpu exit arm64: KVM: vgic-v3: Reset LRs at boot time arm64: KVM: vgic-v3: Do not save an LR known to be empty arm64: KVM: vgic-v3: Save maintenance interrupt state only if required arm64: KVM: vgic-v3: Avoid accessing ICH registers KVM: arm/arm64: vgic-v2: Make GICD_SGIR quicker to hit KVM: arm/arm64: vgic-v2: Only wipe LRs on vcpu exit KVM: arm/arm64: vgic-v2: Reset LRs at boot time KVM: arm/arm64: vgic-v2: Do not save an LR known to be empty KVM: arm/arm64: vgic-v2: Move GICH_ELRSR saving to its own function KVM: arm/arm64: vgic-v2: Save maintenance interrupt state only if required KVM: arm/arm64: vgic-v2: Avoid accessing GICH registers KVM: s390: allocate only one DMA page per VM KVM: s390: enable STFLE interpretation only if enabled for the guest KVM: s390: wake up when the VCPU cpu timer expires KVM: s390: step the VCPU timer while in enabled wait KVM: s390: protect VCPU cpu timer with a seqcount KVM: s390: step VCPU cpu timer during kvm_run ioctl ...

Pull timer updates from Thomas Gleixner: "The timer department delivers this time: - Support for cross clock domain timestamps in the core code plus a first user. That allows more precise timestamping for PTP and later for audio and other peripherals. The ptp/e1000e patches have been acked by the relevant maintainers and are carried in the timer tree to avoid merge ordering issues. - Support for unregistering the current clocksource watchdog. That lifts a limitation for switching clocksources which has been there from day 1 - The usual pile of fixes and updates to the core and the drivers.
