Arthur Jones 8f140b407f IB/ipath: Shadow the gpio_mask register ... Once upon a time, GPIO interrupts were rare. But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.
