* MIPS: Netlogic: update iomap.h for XLP9XXJayachandran C2014-01-24
| | | | | | | | | | | | | Most IO block offsets have changed in XLP9XX. Update iomap.h to add the new addresses of different SoC blocks like PIC, SYS, UART etc. that are needed by the base code. On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus corresponding to the node. Update iomap code to reflect this.

* MIPS: Netlogic: Add MSI support for XLPJayachandran C2014-01-24
| | | | | | | | | | | | | | | | | | | | | Add MSI chip and MSIX chip definitions. For MSI, we map the link interrupt to a MSI link IRQ which will do a second level of dispatch based on the MSI status register. The MSI chip definitions use the MSI enable register to enable and disable the MSI irqs. For MSI-X, we split the 32 available MSI-X vectors across the four PCIe links (8 each). These PIC interrupts generate an IRQ per link which uses a second level dispatch as well. The MSI-X chip definition uses the standard functions to enable and disable interrupts.

* MIPS: Malta: mux & enable SERIRQ interruptPaul Burton2014-01-23
| | | | | | | | | | | | | | | This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ pin of the PIIX4 and to enable that interrupt. The kernel depends upon the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but previously would not configure it, instead relying upon the bootloader having done so. If that is not the case then the typical result is that the system appears to hang once it reaches userland as no output is displayed on the UART.

* MIPS: Support for 64-bit FP with O32 binariesPaul Burton2014-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CPUs implementing MIPS32 R2 may include a 64-bit FPU, just as MIPS64 CPUs do. In order to preserve backwards compatibility a 64-bit FPU will act like a 32-bit FPU (by accessing doubles from the least significant 32 bits of an even-odd pair of FP registers) when the Status.FR bit is zero, again just like a mips64 CPU. The standard O32 ABI is defined expecting a 32-bit FPU, however recent toolchains support use of a 64-bit FPU from an O32 MIPS32 executable. When an ELF executable is built to use a 64-bit FPU a new flag (EF_MIPS_FP64) is set in the ELF header. With this patch the kernel will check the EF_MIPS_FP64 flag when executing an O32 binary, and set Status.FR accordingly. The addition of O32 64-bit FP support lessens the opportunity for optimisation in the FPU emulator, so a CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option is introduced to allow this support to be disabled for those that don't require it. Inspired by an earlier patch by Leonid Yegoshin, but implemented more cleanly & correctly.

There was a lot of work on the PPC side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view. On the x86 side there are nested virtualization improvements and a few bugfixes. ARM got transparent huge page support, improved overcommit, and support for big endian guests. Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions. This includes some nVidia cards on Windows, that fail to start without these patches and the corresponding userspace changes" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (146 commits) kvm, vmx: Fix lazy FPU on nested guest arm/arm64: KVM: PSCI: propagate caller endianness to the incoming vcpu arm/arm64: KVM: MMIO support for BE guest kvm, cpuid: Fix sparse warning kvm: Delete prototype for non-existent function kvm_check_iopl kvm: Delete prototype for non-existent function complete_pio hung_task: add method to reset detector pvclock: detect watchdog reset at pvclock read kvm: optimize out smp_mb after srcu_read_unlock srcu: API for barrier after srcu read unlock KVM: remove vm mmap method KVM: IOMMU: hva align mapping page size KVM: x86: trace cpuid emulation when called from emulator KVM: emulator: cleanup decode_register_operand() a bit KVM: emulator: check rex prefix inside decode_register() KVM: x86: fix emulation of "movzbl %bpl, %eax" kvm_host: typo fix KVM: x86: emulate SAHF instruction MAINTAINERS: add tree for kvm.git Documentation/kvm: add a 00-INDEX file ...
