2013-06-12arm64: KVM: enable initialization of a 32bit vcpuMarc Zyngier1-0/+1
Wire the init of a 32bit vcpu by allowing 32bit modes in pstate, and providing sensible defaults out of reset state. This feature is of course conditioned by the presence of 32bit capability on the physical CPU, and is checked by the KVM_CAP_ARM_EL1_32BIT capability.

2013-06-12arm64: KVM: define 32bit specific registersMarc Zyngier1-1/+6
Define the 32bit specific registers (SPSRs, cp15...). Most CPU registers are directly mapped to a 64bit register (r0->x0...). Only the SPSRs have separate registers. cp15 registers are also mapped into their 64bit counterpart in most cases.

2012-10-18arm64: ptrace: make structure padding explicit for debug registersWill Deacon1-1/+2
The user_hwdebug_state structure contains implicit padding to conform to the alignment requirements of the AArch64 ABI (namely that aggregates must be aligned to their most aligned member). This patch fixes the ptrace functions operating on struct user_hwdebug_state so that the padding is handled correctly.
