From 5b3e34315a8b2d985299735d685c71d481815bef Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 8 Feb 2022 20:08:54 +0000 Subject: [PATCH] include: Move QEMU_MAP_* constants to mmap-alloc.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The QEMU_MAP_* constants are used only as arguments to the qemu_ram_mmap() function. Move them to mmap-alloc.h, where that function's prototype is defined.
