类型参数名称
struct mpc_intsrc *m
219  Define the default level of output to be very little* This can be turned up by using apic=verbose for more* information and apic=debug for _lots_ of information.* apic_verbosity is defined in apic.c(APIC_VERBOSE, "Int: type %d, pol %d, trig %d, bus %02x, IRQ %02x, APIC ID %x, APIC INT %02x\n", irqtype, irqflag & 3, (irqflag >> 2) & 3, srcbus, srcbusirq, dstapic, dstirq)
224  以i小于# of MP IRQ source entries 循环
225  如果非内存比较则返回
229  memcpy( & MP IRQ source entries [# of MP IRQ source entries ], m, m的长度)
230  如果# of MP IRQ source entries 先自加恒等于MAX_IRQ_SOURCES则panic - halt the system*@fmt: The text string to print* Display a message, then perform cleanups.* This function never returns.
