[PATCH] Fix build error in <linux/irq.h>

[Ralf Baechle]

<linux/irq.h> relies on <linux/gfp.h> and <linux/topology.h> having been
included previous.  If not, the errors like below will result.

  CC      arch/mips/mti-malta/malta-int.o
In file included from /home/ralf/src/linux/linux-queue/arch/mips/mti-malta/malta-int.c:25:
/home/ralf/src/linux/linux-queue/include/linux/irq.h: In function âinit_alloc_desc_masksâ:

/home/ralf/src/linux/linux-queue/include/linux/irq.h:446: error: âGFP_ATOMICâ undeclared (first use in this function)
/home/ralf/src/linux/linux-queue/include/linux/irq.h:446: error: (Each undeclared identifier is reported only once
/home/ralf/src/linux/linux-queue/include/linux/irq.h:446: error: for each function it appears in.)
make[3]: *** [arch/mips/mti-malta/malta-int.o] Error 1
make[2]: *** [arch/mips/mti-malta] Error 2
make[1]: *** [sub-make] Error 2

Fixed by including the two missing headers.
