Pierre-Clément Tosi ea9d7c83d1 KVM: arm64: Fix __pkvm_init_switch_pgd call ABI ... Fix the mismatch between the (incorrect) C signature, C call site, and asm implementation by aligning all three on an API passing the parameters (pgd and SP) separately, instead of as a bundled struct. Remove the now unnecessary memory accesses while the MMU is off from the asm, which simplifies the C caller (as it does not need to convert a VA struct pointer to PA) and makes the code slightly more robust by offsetting the struct fields from C and properly expressing the call to the C compiler (e.g. type checker and kCFI).
