For migration, however, we currently always migrate the offset between the guest and the vm_clock, even if the RTC clock is not the same as the vm_clock; this was an attempt to retain migration backwards compatibility. Unfortunately this results in the RTC behaving oddly across a VM state save and restore -- since the VM clock stands still across save-then-restore, regardless of how much real world time has elapsed, the guest RTC ends up out of sync with the host RTC in the restored VM. Fix this by migrating the raw tick_offset. To retain migration compatibility as far as possible, we have a new property migrate-tick-offset; by default this is 'true' and we will migrate the true tick offset in a new subsection; if the incoming data has no subsection we fall back to the old vm_clock-based offset information, so old->new migration compatibility is preserved. For complete new->old migration compatibility, the property is set to 'false' for 4.0 and earlier machine types (this will only affect 'virt-4.0' and below, as none of the other pl031-using machines are versioned).

Now that we're using the MVFR0 register fields to gate the existence of VFP instructions, we need to set up the correct values in the cpu->isar structure so that we still provide an FPU to the guest. This fixes a regression in the arm926 and arm1026 CPUs, which are the only ones that both have VFP and are ARMv5 or earlier. This regression was introduced by the VFP refactoring, and more specifically by commits 1120827fa182f0e76 and 266bd25c485597c, which accidentally disabled VFP short-vector support and double-precision support on these CPUs.

Whether this is a Secure HF or a NonSecure HF depends on several things. If AIRCR.BFHFNMINS is 0 then HF is always Secure, because there is no NonSecure HardFault. Otherwise, the answer depends on whether the 'underlying exception' (MemManage, BusFault, SecureFault) targets Secure or NonSecure. (In the pseudocode, this is handled in the Vector() function: the final exc.isSecure is calculated by looking at the exc.isSecure from the exception returned from the memory access, not the isSecure input argument.) We weren't doing this correctly, because we were looking at the target security domain of the exception we were trying to load the vector table entry for. This produces errors of two kinds: * a load from the NS vector table which hits the "NS access to S memory" SecureFault should end up as a Secure HardFault, but we were raising an NS HardFault * a load from the S vector table which causes a BusFault should raise an NS HardFault if BFHFNMINS == 1 (because in that case all BusFaults are NonSecure), but we were raising a Secure HardFault Correct the logic. We also fix a comment error where we claimed that we might be escalating MemManage to HardFault, and forgot about SecureFault. (Vector loads can never hit MPU access faults, because they're always aligned and always use the default address map.)
