Lothar Waßmann 56b7eec01d ARM: mxs: Fix BUG() when invoking mxs_restart() from interrupt context ... The mxs_restart() function uses of_iomap() which triggers the following BUG_ON(in_interrupt()) when called in interrupt context (e.g. thru SYSRQ-B): SysRq : Resetting ------------[ cut here ]------------ kernel BUG at mm/vmalloc.c:1310!
