Perform the entire operation inline, instead of raising EXCP_BREAK to do the work in mb_cpu_do_interrupt. This fixes a bug in that brki rd, imm, for imm != 0x18 is not supposed to set MSR_BIP. This fixes a bug in that imm == 0 is the reset vector and 0x18 is the debug vector, and neither should raise a tcg exception in system mode. Introduce EXCP_SYSCALL for microblaze-linux-user.

Drop that and merely check use_fpu == 2. Tested-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com> Reviewed-by: Edgar E.
