Review on v1 has gone quiet, so here's v2 which addresses the feedback
received for v1. Thanks to all who have taken the time to review it so
far.
This patchset primarily adds support for FPU and MIPS SIMD Architecture
(MSA) in MIPS KVM guests to QEMU. It depends on the KVM patchset which I
recently submitted to add the corresponding hypervisor support to KVM
("[PATCH 00/20] MIPS: KVM: Guest FPU & SIMD (MSA) support").
All comments welcome.
Changes in v2:
- Moved most of patch 7 and updates to linux-headers/linux/kvm.h from
patches 8 and 9 into a new patch 1, which is purely for reference
(Paolo).
- Add the changes to MIPS_CP0_{32,64} macros from v1 patch 7 to patch 2,
since the rest of that patch is now unnecessary and the change is
along the same lines as patch 2 (not added Leon's Reviewed-by to this
patch due to that non-reviewed change).
- Fix line wrapping of kvm_mips_get_one_reg() calls from Config4 and
Config5 in patch 5 (Leon).
- Change (1 << x) to (1U << x) in important places in patch 5, 8 & 9 to
avoid compiler defined behaviour (Leon).
