Before submitting a patch, please always first build it with "make warn",
and then fix them all:

cc -c -g -DPPC -m32 -D_FILE_OFFSET_BITS=64 -fPIC -DGDB_7_3_1  ppc.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector
ppc.c:71: warning: type defaults to ‘int’ in declaration of ‘ppc_process_elf_notes’
ppc.c: In function ‘ppc_init’:
ppc.c:85: warning: assignment from incompatible pointer type
cc -c -g -DPPC -m32 -D_FILE_OFFSET_BITS=64 -fPIC -DGDB_7_3_1  netdump.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector
cc -c -g -DPPC -m32 -D_FILE_OFFSET_BITS=64 -fPIC -DGDB_7_3_1  diskdump.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector
diskdump.c:276: warning: no previous prototype for ‘ppc_process_elf_notes’
diskdump.c: In function ‘ppc_process_elf_notes’:
diskdump.c:279: warning: ‘len’ may be used uninitialized in this function

I don't feel comfortable accepting this piece as is -- can you restrict it
to just PPC?:
