irq: convert irq/vector numbers to unsigned Currently irq and vector numbers are used inconsistently. * Sometimes vector or irq ids is used in bit operations, indicating that they should be unsigned (which is required by MISRA C). * At the same time we use -1 to indicate an unknown irq (in common_register_handler()) or unavailable irq (in alloc_irq()). Also (irq < 0) or (vector < 0) are used for error checking. These indicate that irq or vector ids should be signed. This patch converts irq and vector numbers to unsigned 32-bit integers, and replace the previous -1 with IRQ_INVALID or VECTOR_INVALID. The branch conditions are updated accordingly.

HV: vioapic: use uint8_t for pins IOAPIC pins always fit in 8-bit and we already use uint8_t for virt_pins. This patch converts pins in vioapic to uint8_t. This is based on Arindam's previous patch ("was: hv: Cleanup and optimise vioapic.c"), with SOS boot failure resolved, format string updated, complex arithmetic expression with implicit type conversion decoupled. Also make some local variables representing interrupt vectors uint32_t.

HV: treewide: drop debug-only helpers in release build There are multiple helpers for collecting info to be printed on the ACRN uart console. They are unreachable code in release builds in which the uart console is removed. To define a precise boundary for safety-related activities, this patch wraps the declarations and definitions to these helpers with "#ifdef HV_DEBUG" so that these unreachable APIs will be dropped in release builds. v1 -> v2: * Fix coding style: no empty lines between #ifdef and the wrapped code. * Also drop get_rte_info() in ioapic.c, which is solely used by get_ioapic_info().

#ifdef HV_DEBUG
fix parted of "missing for discarded return value" MISRA C required that return value should be used, missing for it should add "(void)" prefix before the function call. Some function can be declared without return value to avoid this problem. Signed-off-by: Huihuang Shi <huihuang.shi@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
