Hi, Here is updated patches to address KVM host support in big endian ARM V7/V8. Changes since previous version [1] and [2]: x) joined both v7 [1] and v8 [2] series into one x) addressed, nearly all, Christoffer's comments to previous patch series x) Fixed few issues in 'ARM: KVM: handle 64bit values passed to mrcc or from mcrr instructions in BE case' that got discovered after moving to the latest v3.15-rc5 kernel x) Fixed issue in supporting 32bit guest by V8 BE KVM host All patches except 'ARM: KVM: one_reg coproc set and get BE fixes', as far as I see, are best possible proposal. 'ARM: KVM: one_reg coproc set and get BE fixes' changes still need more discussion. Patch included with this series covers one possible solution, I'll post notes about other approach previously suggested by Alex Graf separately. The patches were tested on top of v3.15-rc5 on TC2 (V7) and fastmodels (V8). Tested all possible combinations of KVM host and guests (V7/V8, BE/LE, 64bit/32bit).
