This means we might cause a data * abort here if the I-TLB and D-TLB aren't seeing the same * picture.  Unfortunately, this does happen.  We live with it. */	.align	5ENTRY(v4t_early_abort)	mrc	p15, 0, r1, c5, c0, 0		@ get FSR	mrc	p15, 0, r0, c6, c0, 0		@ get FAR	do_thumb_abort	ldreq	r3, [r2]			@ read aborted ARM instruction	bic	r1, r1, #1 << 11 | 1 << 10	@ clear bits 11 and 10 of FSR	tst	r3, #1 << 20			@ check write	orreq	r1, r1, #1 << 11	mov	pc, lr
