Richard Henderson 88e74b6122 target/microblaze: Collected fixes for env->iflags ... There are several problems here that can result in soft lockup, depending on exactly where an interrupt or exception is delivered: Include BIMM_FLAG in IFLAGS_TB_MASK, since it needs to follow D_FLAG. Ensure that iflags is 0 when entering an interrupt/exception handler. Add mb_cpu_synchronize_from_tb to restore iflags from tb->flags. The change to t_sync_flags is cosmetic, but makes the code clearer. This fixes the reported regression in acceptance/replay_kernel.py.
