in almost all start.S under arm cpu directory,
in this marco below _________ _.macro irq_save_user_regs
the asm code use R8 --- the GOT of u-boot
so after a interrupt occurs, we can not use export functions correctly any more because that macro change the R8 reg

Unix is like a toll road on which you have to stop every 50 feet to
pay another nickel. But hey! You only feel 5 cents poorer each time.
