Header files in arch/arm/*/include/mach included from arch/arm/include/asm/*.h are there to provide necessary definitions for either the rest of the kernel or the ARM specific parts. They shouldn't be polluted with *any* platform private stuff which is not absolutely necessary to satisfy the rest of the kernel. Hence move the OMAP specific SMP boot functions to different header instead of keeping them in 'plat/smp.h' which gets included indirectly by linux/smp.h The patch is outcome of the discussion in below thread: http://www.spinics.net/lists/arm-kernel/msg120363.html Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
