Patch borrowed from OpenEmbedded, available at
-recipes/libaio/libaio-0.3.106/00_arches.patch in their source
-tree. The patch has been adapted to remove the ARM-related
-definitions, since they have been merged in later versions of libaio.
+/meta/recipes-extended/libaio/libaio/00_arches.patch in their source
+tree. This patch has been modified to only add the MIPS definitions.
-The patch adds various architecture specific definitions (syscall
-number and macros) for m68k, MIPS, PA/RISC and Sparc. Amongst these,
-Buildroot mostly only cares about MIPS, but it was just easier to take
-the whole OpenEmbedded patch.
+The patch adds MIPS specific definitions (syscall number and macros).
