[PATCH 0/4] ARM: OMAP: raw read and write endian fix

by Taras Kondratiuk

This series does trivial replacement of __raw_xxx functions with xxx_relaxed endian-neutral variants in 'mach-omap2' and 'plat-omap' directories. Some code here most probably won't be used in BE mode (like debug-leds for OMAP1 boards), but changes are made anyway to remove __raw_xxx() functions completely and simplify future grep'ing for new __raw_xxx() entries. This is a part of RFC series [1]. Based on v3.13-rc5.

[PATCH v6 00/12] In-kernel PSCI v0.2 emulation for KVM ARM/ARM64

by Anup Patel

Currently, KVM ARM/ARM64 only provides in-kernel emulation of Power State and Coordination Interface (PSCI) v0.1. This patchset aims at providing newer PSCI v0.2 for KVM ARM/ARM64 VCPUs such that it does not break current KVM ARM/ARM64 ABI. The user space tools (i.e. QEMU or KVMTOOL) will have to explicitly enable KVM_ARM_VCPU_PSCI_0_2 feature using KVM_ARM_VCPU_INIT ioctl for providing PSCI v0.2 to VCPUs. Changlog: V6: - Introduce uapi/linux/psci.h for sharing PSCI defines between ARM kernel, ARM64 kernel, KVM ARM/ARM64 and user space - Make CPU_SUSPEND emulation similar to WFI emulation V5: - Have separate last patch to advertise KVM_CAP_ARM_PSCI_0_2 - Use kvm_psci_version() in kvm_psci_vcpu_on() - Return ALREADY_ON for PSCI v0.2 CPU_ON if VCPU is not paused - Remove per-VCPU suspend context - As-per PSCI v0.2 spec, only current CPU can suspend itself V4: - Implement all mandatory functions required by PSCI v0.2 V3: - Make KVM_ARM_VCPU_PSCI_0_2 feature experiementatl for now so that it fails for user space till all mandatory PSCI v0.2 functions are emulated by KVM ARM/ARM64 - Have separate patch for making KVM_ARM_VCPU_PSCI_0_2 feature available to user space. This patch can be defferred for now V2: - Don't rename PSCI return values KVM_PSCI_RET_NI and KVM_PSCI_RET_INVAL - Added kvm_psci_version() to get PSCI version available to VCPU - Fixed grammer in Documentation/virtual/kvm/api.txt V1: - Initial RFC PATCH Anup Patel (12): KVM: Add capability to advertise PSCI v0.2 support ARM/ARM64: KVM: Add common header for PSCI related defines ARM/ARM64: KVM: Add base for PSCI v0.2 emulation KVM: Documentation: Add info regarding KVM_ARM_VCPU_PSCI_0_2 feature ARM/ARM64: KVM: Make kvm_psci_call() return convention more flexible KVM: Add KVM_EXIT_SYSTEM_EVENT to user space API header ARM/ARM64: KVM: Emulate PSCI v0.2 SYSTEM_OFF and SYSTEM_RESET ARM/ARM64: KVM: Emulate PSCI v0.2 AFFINITY_INFO ARM/ARM64: KVM: Emulate PSCI v0.2 MIGRATE_INFO_TYPE and related functions ARM/ARM64: KVM: Fix CPU_ON emulation for PSCI v0.2 ARM/ARM64: KVM: Emulate PSCI v0.2 CPU_SUSPEND ARM/ARM64: KVM: Advertise KVM_CAP_ARM_PSCI_0_2 to user space Documentation/virtual/kvm/api.txt | 17 +++ arch/arm/include/asm/kvm_host.h | 2 +- arch/arm/include/asm/kvm_psci.h | 6 +- arch/arm/include/uapi/asm/kvm.h | 19 +-- arch/arm/kvm/arm.c | 1 + arch/arm/kvm/handle_exit.c | 10 +- arch/arm/kvm/psci.c | 233 ++++++++++++++++++++++++++++++++++--- arch/arm64/include/asm/kvm_host.h | 2 +- arch/arm64/include/asm/kvm_psci.h | 6 +- arch/arm64/include/uapi/asm/kvm.h | 21 ++-- arch/arm64/kvm/handle_exit.c | 10 +- include/uapi/linux/Kbuild | 1 + include/uapi/linux/kvm.h | 9 ++ include/uapi/linux/psci.h | 55 +++++++++ 14 files changed, 344 insertions(+), 48 deletions(-) create mode 100644 include/uapi/linux/psci.h -- 1.7.9.5

[PATCH] spi: Fix handling of cs_change in core implementation

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The core implementation of cs_change didn't follow the documentation which says that cs_change in the middle of the transfer means to briefly deassert chip select, instead it followed buggy drivers which change the polarity of chip select. Use a delay of 10us between deassert and reassert simply from pulling numbers out of a hat.
