scripts/coccinelle/memory-region-init-ram.cocci: New script
Add a coccinelle script that can be used to automatically convert manual sequences of memory_region_init_ram_nomigrate() vmstate_register_ram{,_global}() to use the new memory_region_init_ram() Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 1499438577-7674-7-git-send-email-peter.maydell@linaro.org
