Change to mman.h around 2.3.99-pre3-pre4

Does anyone know why the file linux/include/asm-ppc/mman.h changed the
values of MCL_CURRENT and MCL_FUTURE around kernel version
2.3.99-pre3-pre4?

This change causes binary incompatibility.

They used to be

#define MCL_CURRENT     0x2000          /* lock all currently mapped pages */
#define MCL_FUTURE      0x4000          /* lock all additions to address space */

but they're now

#define MCL_CURRENT	1		/* lock all current mappings */
#define MCL_FUTURE	2		/* lock all future mappings */
