qemu-common: add QEMU_ALIGN_DOWN() and QEMU_ALIGN_UP() macros
Add macros for aligning a number to a multiple, for example: QEMU_ALIGN_DOWN(500, 2000) = 0 QEMU_ALIGN_UP(500, 2000) = 2000 Since ALIGN_UP() is a common macro name use the QEMU_* namespace prefix. Hopefully this will protect us from included headers that leak something with a similar name. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
