[Qemu-devel] [PATCH v3 09/29] dump: remove dumping stuff from cpu-all.h

[Paolo Bonzini <pbonzini@redhat.com>]

This simplifies things, because they will only be included for softmmu
targets and because the stubs are taken out-of-line in separate files,
which in the future could even be compiled only once.
