  9. arch/armv8-m: Supports interrupt nesting between TEE and REE 

    The first time interrupt nesting occurs between REE and TEE,
CURRENT_REGS needs to be set.

If TEE nesting REE breaks, then EXC_RETURN.S=0,EXC_RETURN.ES=1;
Conversely, EXC_RETURN.S=1,EXC_RETURN.ES=0;
Interrupt nesting between TEE and REE can be determined based
on the S and ES bits of EXC_RETURN.
Only once nesting between TEE and REE is supported, and cyclic
nesting between TEE and REE is not supported.
