Subject: [Qemu-devel] [PATCH 30/38] memory: split cpu_physical_memory_* functions to its own include
Date: Tue, 17 Dec 2013 16:26:06 +0100 [thread overview]
Message-ID: <1387293974-24718-31-git-send-email-quintela@redhat.com> (raw)
In-Reply-To: <1387293974-24718-1-git-send-email-quintela@redhat.com>
All the functions that use ram_addr_t should be here.
