└─> Cortex-A76: Software Step might prevent interrupt recognition

This option adds a workaround for Arm Cortex-A76 erratum 1463225.

On the affected Cortex-A76 cores (r0p0 to r3p1), software stepping
of a system call instruction (SVC) can prevent recognition of
subsequent interrupts when software stepping is disabled in the
exception handler of the system call and either kernel debugging
is enabled or VHE is in use.

Work around the erratum by triggering a dummy step exception
when handling a system call from a task that is being stepped
in a VHE configuration of the kernel.

If unsure, say Y.
