hw/intc/arm_gicv3_its: Fix event ID bounds checks
In process_its_cmd() and process_mapti() we must check the event ID against a limit defined by the size field in the DTE, which specifies the number of ID bits minus one. Convert this code to our num_foo convention: * change the variable names * use uint64_t and 1ULL when calculating the number of valid event IDs, because DTE.SIZE is 5 bits and so num_eventids may be up to 2^32 * fix the off-by-one error in the comparison Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Message-id: 20220111171048.3545974-2-peter.maydell@linaro.org
