[PATCH] sparse: misc cleanups

[PATCH] sparse: misc cleanups

all sorts of minor stuff - basically, all chunks are independent here,
but IMO that one is not worth splitting.  Contains:
	* pmac_cpufreq.c: declaration in the middle of a block.
	* sys_ia32.c: couple of trivial annotations.
	* ipmi_si_intf.c: should be using asm/irq.h instead of linux/irq.h
	* synclink_cs.c: assignment-in-conditional with nobody ever looking
at the variable we are assigning to afterwards; variable removed.
	* sbni.c: s/__volatile/__volatile__
	* matroxfb_base.h: got rid of ((u32 *)p)++
	* asm-ppc/checksum.h and asm-sparc64/floppy.h: NULL noise removal
	* amd64 compat.h: missing L in long constant.
	* mtd-abi.h: annotated ioctl structure
	* sysctl.c: corrected annotations in extern
