2015-05-19powerpc/kvm: Disable in-kernel MPIC emulation for PREEMPT_RT_FULLBogdan Purcareata
Current in-kernel MPIC emulation for PowerPC is unsuitable for RT. More specifically, the MPIC lock becomes a sleeping mutex, causing concurrency issues on a KVM guest enter. Converting the lock to a raw_spinlock is still not a viable solution, since the current implementation is prone to induce large latencies with preemption and irqs disabled on the host kernel. Patch aready applied in the upstream 3.18.13 RT patch, version 9 [1].

Since both ppc and ppc64 have LE variants which are now reported by uname, add that flag (__AUDIT_ARCH_LE) to syscall_get_arch() and add AUDIT_ARCH_PPC64LE variant. Without this, perf trace and auditctl fail. Mainline kernel reports ppc64le (per a058801) but there is no matching AUDIT_ARCH_PPC64LE. Since 32-bit PPC LE is not supported by audit, don't advertise it in AUDIT_ARCH_PPC* variants.

2015-03-30seccomp,x86,arm,mips,s390: Remove nr parameter from secure_computingBogdan Purcareata
The secure_computing function took a syscall number parameter, but it only paid any attention to that parameter if seccomp mode 1 was enabled. Rather than coming up with a kludge to get the parameter to work in mode 2, just remove the parameter. To avoid churn in arches that don't have seccomp filters (and may not even support syscall_get_nr right now), this leaves the parameter in secure_computing_strict, which is now a real function. For ARM, this is a bit ugly due to the fact that ARM conditionally supports seccomp filters. Fixing that would probably only be a couple of lines of code, but it should be coordinated with the audit maintainers. This will be a slight slowdown on some arches. The right fix is to pass in all of seccomp_data instead of trying to make just the syscall nr part be fast. This is a prerequisite for making two-phase seccomp work cleanly.

2015-03-26arm: KVM: Don't return PSCI_INVAL if waitqueue is inactiveChristoffer Dall
The current KVM implementation of PSCI returns INVALID_PARAMETERS if the waitqueue for the corresponding CPU is not active. This does not seem correct, since KVM should not care what the specific thread is doing, for example, user space may not have called KVM_RUN on this VCPU yet or the thread may be busy looping to user space because it received a signal; this is really up to the user space implementation. Instead we should check specifically that the CPU is marked as being turned off, regardless of the VCPU thread state, and if it is, we shall simply clear the pause flag on the CPU and wake up the thread if it happens to be blocked for us. Further, the implementation seems to be racy when executing multiple VCPU threads. There really isn't a reasonable user space programming scheme to ensure all secondary CPUs have reached kvm_vcpu_first_run_init before turning on the boot CPU. Therefore, set the pause flag on the vcpu at VCPU init time (which can reasonably be expected to be completed for all CPUs by user space before running any VCPUs) and clear both this flag and the feature (in case the feature can somehow get set again in the future) and ping the waitqueue on turning on a VCPU using PSCI.

PMCs on PowerPC increases towards 0x80000000 and triggers an overflow interrupt when the msb is set to collect a sample. Therefore, to setup for the next sample collection, pmu_start should set the pmc value to 0x80000000 - left instead of left which incorrectly delays the next overflow interrupt. Same as commit 9a45a9407c69 ("powerpc/perf: power_pmu_start restores incorrect values, breaking frequency events") for book3s.
