[PATCH] warning: fix arch x86 kernel io_apic c

[Ingo Molnar]

fix warning:

  arch/x86/kernel/io_apic.c: In function âprint_local_APICâ:
  arch/x86/kernel/io_apic.c:1786: warning: format â%08xâ expects type âunsigned intâ, but argument 2 has type âu64â
  arch/x86/kernel/io_apic.c:1787: warning: format â%08xâ expects type âunsigned intâ, but argument 2 has type âu64â

By creating uniform behavior on 32-bit and 64-bit and printing out the ICR
value in two 32-bit words.

Code has changed:

   text	   data	    bss	    dec	    hex	filename
  22901	  19650	  17040	  59591	   e8c7	io_apic.o.before
  22899	  19650	  17040	  59589	   e8c5	io_apic.o.after

Due to the 32-bit cast narrowing the printed out value on 64-bit.
