[PATCH] kill include/linux/platform.h, default_idle() cleanup
include/linux/platform.h contained nothing that was actually used except the default_idle() prototype, and is therefore removed by this patch. This patch does the following with the platform specific default_idle() functions on different architectures: - remove the unused function: - parisc - sparc64 - make the needlessly global function static: - arm - h8300 - m68k - m68knommu - s390 - v850 - x86_64 - add a prototype in asm/system.h: - cris - i386 - ia64 Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Patrick Mochel <mochel@digitalimplant.org> Acked-by: Kyle McMartin <kyle@parisc-linux.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
