[Qemu-devel] [PULL 06/16] target-ppc: Split out SREGS get/put functions

[David Gibson]

Currently the getting and setting of Power MMU registers (sregs) take up
large inline chunks of the kvm_arch_get_registers() and
kvm_arch_put_registers() functions.  Especially since there are two
variants (for Book-E and Book-S CPUs), only one of which will be used in
practice, this is pretty hard to read.

This patch splits these out into helper functions for clarity.  No
functional change is expected.
