If a FIQ happens during this time, the ++ * virtual memory space can be partly or entirely disordered or missing. ++ * ++ * 2) Because vmalloc() is used when a module is inserted, THIS FIQ ++ * ISR HAS TO BE IN THE MONOLITHIC KERNEL, not a module.

The reason is the same as above, a ++ * FIQ could happen while even the ISR is not present in virtual memory ++ * space due to pagetables being changed at the time. ++ * ++ * 3) You can't call any Linux API code except simple macros ++ * - understand that FIQ can come in at any time, no matter what ++ * state of undress the kernel may privately be in, thinking it ++ * locked the door by turning off interrupts... FIQ is an ++ * unstoppable monster force (which is its value) ++ * - they are not vmalloc()'d memory safe ++ * - they might do crazy stuff like sleep: FIQ pisses fire and ++ * is not interested in 'sleep' that the weak seem to need ++ * - calling APIs from FIQ can re-enter un-renterable things ++ * - summary: you cannot interoperate with linux APIs directly in the FIQ ISR ++ * ++ * If you follow these rules, it is fantastic, an extremely powerful, solid, ++ * genuine hard realtime feature. ++ */ ++ ++static void (*current_fiq_c_isr)(void);
