[PATCH] powerpc: Kdump header cleanup
We need to know the base address of the kdump kernel even when we're not a kdump kernel, so add a #define for it. Move the logic that sets the kdump kernelbase into kdump.h instead of page.h. Rename kdump_setup() to setup_kdump_trampoline() to make it clearer what it's doing, and add an empty definition for the !CRASH_DUMP case to avoid a Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
