Because slot 1 of one instr bundle crosses border of two consecutive 8-bytes, kprobe on slot 1 is disabled. This patch enables kprobe on slot1, it only replaces higher 8-bytes of the instruction bundle and changes the exception code to ignore the low 12 bits of the break number (which is across the border in the lower 8-bytes of the bundle). For those instructions which must execute regardless qp bits, kprobe on slot 1 is still disabled. Signed-off-by: bibo,mao <bibo.mao@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
