powerpc/kexec: Enable kexec_file_load() syscall
Define the Kconfig symbol so that the kexec_file_load() code can be built, and wire up the syscall so that it can be called. Signed-off-by: Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

This is a new version of the kexec system call. This call is
|
||||
file based and takes in file descriptors as system call arguments
|

for kernel and initramfs as opposed to a list of segments as is the
|
||||
case for the older kexec call.
