I added a line that initializes the flush_icache_page pointer in sb1_cache_init. The below method worked. The SMP kernel boots fine now. Removing parts of local_sb1_flush_icache_page doesn't help. It looks like flush_icache_page in mm/memory.c:do_no_page is needed. Removing it will fail the boot process. I am wondering if people have booted the latest tree on non-Broadcom boards...curious to know if the removal of flush_icache_page has affected them.
