/* Platforms supported by PPC64 */
#define PLATFORM_PSERIES      0x0100
#define PLATFORM_PSERIES_LPAR 0x0101
#define PLATFORM_ISERIES_LPAR 0x0201
#define PLATFORM_LPAR         0x0001
#define PLATFORM_POWERMAC     0x0400
#define PLATFORM_MAPLE        0x0500

Hrm... this will trigger on Maple too... Should I change Maple
definition ? That would break kexec of maple from existing to newer
kernels though.

* [PATCH] ppc64: actually call prom_send_capabilities

When I sent in the patch adding the code for the kernel to tell the
firmware about its capabilities on pSeries machines, I included the
function to give the capabilities to firmware but somehow forgot the
hunk that adds the call to the new function.  This patch adds the
call.
