Argh. After adding this patch, kexec-tools no longer builds --with-xen:

gcc -g -O2 -fno-strict-aliasing -Wall -Wstrict-prototypes -I./include -I./util_lib/include -Iinclude/  -I./kexec/arch/x86_64/include  -c -MD -o kexec/arch/i386/kexec-x86-common.o kexec/arch/i386/kexec-x86-common.c
kexec/arch/i386/kexec-x86-common.c: In function ‘xen_e820_to_kexec_type’:
kexec/arch/i386/kexec-x86-common.c:158:8: error: ‘E820_PMEM’ undeclared (first use in this function)
   case E820_PMEM:
        ^

   case E820_PRAM:

This happens, because other E820_* macros are defined
in /usr/include/xenctrl.h, but not E820_PMEM and E820_PRAM.

I'm unsure how to fix it.
