KVM: MIPS: Fix trace event to save PC directly Currently the guest exit trace event saves the VCPU pointer to the structure, and the guest PC is retrieved by dereferencing it when the event is printed rather than directly from the trace record. This isn't safe as the printing may occur long afterwards, after the PC has changed and potentially after the VCPU has been freed. Usually this results in the same (wrong) PC being printed for multiple trace events. It also isn't portable as userland has no way to access the VCPU data structure when interpreting the trace record itself. Lets save the actual PC in the structure so that the correct value is accessible later.

MIPS: KVM: Add KScratch registers Allow up to 6 KVM guest KScratch registers to be enabled and accessed via the KVM guest register API and from the guest itself (the fallback reading and writing of commpage registers is sufficient for KScratch registers to work as expected). User mode can expose the registers by setting the appropriate bits of the guest Config4.KScrExist field. KScratch registers that aren't usable won't be writeable via the KVM Ioctl API.

MIPS: KVM: Add kvm_aux trace event Add a MIPS specific trace event for auxiliary context operations (notably FPU and MSA). Unfortunately the generic kvm_fpu trace event isn't flexible enough to handle the range of interesting things that can happen with FPU and MSA context. The type of state being operated on is traced: - FPU: Just the FPU registers. - MSA: Just the upper half of the MSA vector registers (low half already loaded with FPU state). - FPU & MSA: Full MSA vector state (includes FPU state). As is the type of operation: - Restore: State was enabled and restored. - Save: State was saved and disabled. - Enable: State was enabled (already loaded). - Disable: State was disabled (kept loaded). - Discard: State was discarded and disabled.
