We use the endianness of interrupts to determine which endianness to
use for the guest kernel memory dump. For machines that support HILE
(powernv8 and up) we have been always generating big endian dump
files.
This patch uses the HILE support recently added to
ppc_interrupts_little_endian to fix the endianness of the dumps for
powernv machines.
Here are two dumps created at different moments:
$ file skiboot.dump
skiboot.dump: ELF 64-bit MSB core file, 64-bit PowerPC ...
$ file kernel.dump
kernel.dump: ELF 64-bit LSB core file, 64-bit PowerPC ...
