Ioannis Glaropoulos 639eb76729 arch: arm: make priv stack guard programming similar to normal guard ... This commit aligns the programming of the privileged stack MPU guard with that of the default stack guard (i.e of supervisor threads). In particular: - the guard is programmed BELOW the address indicated in arch.priv_stack_start; it is, therefore, similar to the default guard that is programmed BELOW stack_info.start. An ASSERT is added to confirm that the guard is programmed inside the thread privilege stack area. - the stack fail check is updated accordningly - arch.priv_stack_start is adjusted in arch_userspace_enter(), to make sure we account for a (possible) guard requirement, that is, if building with CONFIG_MPU_STACK_GUARD=y.
