478a2db828 irqchip/irq-mvebu-gicp: Allocate enough memory for spi_bitmap
BITS_TO_LONGS() gives us the number of longs we need, but we want to
allocate the number of bytes.

a68a63cb4d irqchip/irq-mvebu-gicp: Add new driver for Marvell GICP
This commit adds a simple driver for the Marvell GICP, a hardware unit
that converts memory writes into GIC SPI interrupts. The driver provides
a number of functions to the ICU driver to allocate GICP interrupts, and
get the physical addresses that the ICUs should write to to set/clear
interrupts.
