+Subject: [PATCH gnumach 1/7] kern: import `macros.h' from x15
+
+Import the macro definitions from the x15 kernel project, and replace
+all similar definitions littered all over the place with it.
+
+Importing this file will make importing code from the x15 kernel
+easier. We are already using the red-black tree implementation and
+the slab allocator from it, and we will import even more code in the
+near future.
+
+* Makefrag.am (libkernel_a_SOURCES): Add new file.
+* kern/list.h: Do not define `structof', include `macros.h' instead.
+* kern/rbtree.h: Likewise.
+* kern/slab.c: Do not define `ARRAY_SIZE', include `macros.h' instead.
+* i386/grub/misc.h: Likewise.
+* kern/macros.h: New file.
