Hi Benjamin,

All error/warnings:
WARNING: arch/powerpc/mm/built-in.o(.cpuinit.text+0x292): Section mismatch in reference from the function .fake_numa_create_new_node() to the variable .init.data:cmdline The function __cpuinit .fake_numa_create_new_node() references

PATCH 1/1 powerpc: rename set_break to avoid naming conflict
With allmodconfig we are getting:
drivers/tty/synclink_gt.c:160:12: error: conflicting types for 'set_break' arch/powerpc/include/asm/debug.h:49:5: note: previous declaration of 'set_break' was here
drivers/tty/synclinkmp.c:526:12: error: conflicting types for 'set_break' arch/powerpc/include/asm/debug.h:49:5: note: previous declaration of 'set_break' was here
This renames set_break to set_breakpoint to avoid this naming conflict
