Hi Christoffer, Marc, Could you please look at updated ARM BE KVM series. We worked separately on specific patches, I believe now they should look OK. Changes since previous V3 version of series [1]: o Updated Review-by Acked-by tags where appropriate o 'ARM: KVM: __kvm_vcpu_run function return result fix in BE case' patch changed __ARMEB__ to CONFIG_CPU_ENDIAN_BE8 as Marc suggested o 'ARM: KVM: one_reg coproc set and get BE fixes' patch was siginificantly reworked based on separate thread discussion with Christoffer - In short summry now we fix only oddball places where reg_[from|to]_user function is used in case target variable mismatching register size o 'ARM64: KVM: fix vgic_bitmap_get_reg function for BE 64bit case' incorporated Christoffer's review comments about code comments (spelling, grammar, etc) o 'ARM64: KVM: set and get of sys registers in BE case' changed patch siginificantly based on separate email thread feedback from Christoffer and Marc - now patch just removes comment about reg_[to|form]_user being little endian, since it handles only 64 bit register size current code is endian agnostic. o 'ARM64: KVM: fix big endian issue in access_vm_reg for 32bit guest' incorporoated Christoffer's review comments - two macros vcpu_cp15_64_high and vcpu_cp15_64_low now introduced which defined differently between BE and LE cases Series were tested on top of v3.15. On V7 4 combinations, BE/LE host x BE/LE guest, were tested with TC2. On V8 8 combinations, BE/LE host x BE/LE guest x 32/64 bit guest, were tested on Fast models.
