[sir_richard] 47676: [HAL]: Implement Bus Handler support for HalGetInterruptVector too. The new functionality now includes support for checking against reserved HAL vectors instead of blindling assining IRQLs/Vectors to callers. A warning is printed on the debug log when the old HAL would've returned different values. Please test. If you have issues, the problem is in the DRIVERS, not this code.
