This patchset gathers together some miscellaneous MIPS KVM (trap & emulate) improvements. Patches 8 and 15 in particular change non-KVM MIPS code, so Acks appreciated. They are used by other patches in the series, so it makes sense I think to keep them together. The patchset is based on my recent MIPS KVM patchsets: [PATCH 0/4] MIPS: KVM: Module + non dynamic translating fixes [PATCH 00/18] MIPS: KVM: Miscellaneous clean-ups [PATCH 0/8] MIPS: KVM: Debug & trace event improvements Changes include: - Patches 1-3: Dynamic translation & emulation fix/cleanups. - Patches 4-7: Dynamic KVM_GET_REG_LIST so it can actually properly list all available registers, which allows for improved robustness of userland, especially for VZ support where the core may implement optional registers that KVM can't opt out of exposing. - Patches 8-11: HWREna / RDHWR handling improvements. - Patch 12: Add guest KScratch registers. - Patches 13-17: Other miscellaneous improvements.
