++/* -------- FIQ handler in C ---------
++ *
++ * Major Caveats for using this
++ * ---------------------------
++ * *
++ * * 1) it CANNOT touch any vmalloc()'d memory, only memory
++ * that was kmalloc()'d. Static allocations in the monolithic kernel
++ * are kmalloc()'d so they are okay. You can touch memory-mapped IO, but
++ * the pointer for it has to have been stored in kmalloc'd memory. The
++ * reason for this is simple: every now and then Linux turns off interrupts
++ * and reorders the paging tables. 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. But the way
++ * it is set up, you can all to enable and disable it from your module
++ * and intercommunicate with it through struct fiq_ipc
++ * fiq_ipc which you can define in
++ * asm/archfiq_ipc_type.h. 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.
