I'm on Debian/stable (binutils 2.18, gcc 4.3.2), so I applied your patches 
to the latest -git checkout:

First, compilation fails with:

cc1: warnings being treated as errors
kexec/arch/ppc/kexec-ppc.c: In function ‘get_base_ranges’:
kexec/arch/ppc/kexec-ppc.c:258: error: value computed is not used
make: *** [kexec/arch/ppc/kexec-ppc.o] Error 1

Somehow a "-" hyphen made it into one of the functions:

Removing this, gets me further, until:


purgatory/arch/ppc/crt.o: In function `__lshrdi3':
(.text+0xf0): multiple definition of `__lshrdi3'
purgatory/arch/ppc/misc.o:(.text+0x50): first defined here
collect2: ld returned 1 exit status
make: *** [purgatory/purgatory.ro] Error 1

And has been defined in purgatory/arch/ppc/crt.S and
./purgatory/arch/ppc/misc.S. Removing it from e.g. crt.S
makes it compile, I have not tested it yet, though :-)

Thanks,
Christian.

PS: Where is -Werror defined? I could not find it anywhere in the kexec 
    source (execpt in arch/mips)...
