2014-06-19target-arm: Introduce per-CPU field for PSCI versionPranavkumar Sawargaonkar
We require to know the PSCI version available to given CPU at potentially many places. Currently, we need to know PSCI version when generating DTB for virt machine. This patch introduce per-CPU 32bit field representing the PSCI version available to the CPU. The encoding of this 32bit field is same as described in PSCI v0.2 spec.

2014-06-19target-arm: Implement kvm_arch_reset_vcpu() for KVM ARM64Pranavkumar Sawargaonkar
To implement kvm_arch_reset_vcpu(), we simply re-init the VCPU using kvm_arm_vcpu_init() so that all registers of VCPU are set to their reset values by in-kernel KVM code.

2014-06-19target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature when possiblePranavkumar Sawargaonkar
Latest linux kernel supports in-kernel emulation of PSCI v0.2 but to enable it we need to select KVM_ARM_VCPU_PSCI_0_2 feature using KVM_ARM_VCPU_INIT ioctl. Also, we can use KVM_ARM_VCPU_PSCI_0_2 feature for VCPU only when linux kernel has KVM_CAP_ARM_PSCI_0_2 capability. This patch updates kvm_arch_init_vcpu() to enable KVM_ARM_VCPU_PSCI_0_2 feature for VCPU when KVM ARM/ARM64 has KVM_CAP_ARM_PSCI_0_2 capability.

2014-06-09target-arm: Fix errors in writes to generic timer control registersPeter Maydell
The code for handling writes to the generic timer control registers had several bugs: * ISTATUS (bit 2) is read-only but we forced it to zero on any write * the check for "was IMASK (bit 1) toggled?" incorrectly used '&' where it should be '^' * the handling of IMASK was inverted: we should set the IRQ if ISTATUS is set and IMASK is clear, not if both are set The combination of these bugs meant that when running a Linux guest that uses the generic timers we would fairly quickly end up either forgetting that the timer output should be asserted, or failing to set the IRQ when the timer was unmasked. The result is that the guest never gets any more timer interrupts.

2014-06-09target-arm: Correct handling of UXN bit in ARMv8 LPAE page tablesIan Campbell
In v8 page tables bit 54 in the PTE is UXN in the EL0/EL1 translation regimes and XN elsewhere. In v7 the bit is always XN. Since we only emulate EL0/EL1 we can just treat this bit as UXN whenever we are in v8 mode. Also correctly extract the upper attributes from the PTE entry, the v8 version tried to avoid extracting the CONTIG bit and ended up with the upper bits being off-by-one. Instead behave the same as v7 and extract (but ignore) the CONTIG bit. This fixes "Bad mode in Synchronous Abort handler detected, code 0x8400000f" seen when modprobing modules under Linux.
