62637ca653 e2k: Add systrace print for access_hw_stacks.

e404c06a2d e2k: Fix syscall restart. 
We cannot just change the IP address in E2K to restart
the instruction because the same register can be read
and written in the same instruction (and many more
situations), but we can create a fake syscall instruction
and restart it.

8b599e5c02 linux-user/aarch64: Introduce sve_vq 
Add an interface function to extract the digested vector length
rather than the raw zcr_el[1] value.  This fixes an incorrect
return from do_prctl_set_vl where we didn't take into account
the set of vector lengths supported by the cpu.

8115fc9368 target/m68k: Fix address argument for EXCP_TRACE 
According to the M68040 Users Manual, section 8.4.3,
Six word stack frame (format 2), Trace (and others) is
supposed to record the next insn in PC and the address
of the trapping instruction in ADDRESS.

Create gen_raise_exception_format2 to record the trapping
pc in env->mmu.ar.  Update m68k_interrupt_all to pass the
value to do_stack_frame.  Update cpu_loop to handle EXCP_TRACE.

710d747b2d target/m68k: Fix pc, c flag, and address argument for EXCP_DIV0 
According to the M68040 Users Manual, section 8.4.3,
Six word stack frame (format 2), Zero Div (and others)
is supposed to record the next insn in PC and the
address of the trapping instruction in ADDRESS.

While the N, Z and V flags are documented to be undefine on DIV0,
the C flag is documented as always cleared.

Update helper_div* to take the instruction length as an argument
and use raise_exception_format2.  Hoist the reset of the C flag
above the division by zero check.

Update m68k_interrupt_all to pass mmu.ar to do_stack_frame.
Update cpu_loop to pass mmu.ar to siginfo.si_addr, as the
kernel does in trap_c().
