armv8/hyp: Enable FPU in EL0/1 when HYP is on The disableFpu() for EL2 traps any FPU instruction to EL2 even if the FPU is enabled for EL0/1 in CPACR_EL1. For EL2, we use CPTR_EL2 to enable/disable trapping FPU instructions. Therefore, we enable FPU for EL0/1 by default so that no additional exceptions will be generated when we enable FPU access in CPTR_EL2.

SELFOUR-806: aarch32 - Implement lazy FP save/restore This commit implements lazy FP save/restore mechanism, required for user threads when they use the FPU. The following caveats take place: * Only support synchronous exceptions. No support for asynchronous ones. * VFP opcodes are used instead of normal instructions to discard compiler warnings/errors. * Support is limited to specific ARM subarchitectures we support and tested this commit on. * Disable the FPU by default if users are not using it to avoid channels. * FPU support is not verified yet. * Will not work properly if using a VM that's running besides other VMs/threads that are using the FPU.
