Changed l4id_t type to integer to recognise negative id values like L4_ANYTHREAD. Added an extremely simple script that cleans and builds everything in right order. Increased boot pmds by one: This is due to the fact that if the 1MB initial allocation area of the kernel is not 1MB-aligned, it is ought to be mapped from the middle of one MB to next, which requires 2 pmds. modified: .gdbinit modified: README new file: buildall.sh modified: include/l4/arch/arm/types.h modified: include/l4/generic/scheduler.h modified: loader/kernel.S modified: loader/main.c modified: loader/mylink.lds modified: loader/start.axf.S modified: src/glue/arm/init.c modified: src/glue/arm/memory.c modified: tasks/fs0/src/bdev.c modified: tasks/mm0/include/kdata.h modified: tasks/mm0/include/vm_area.h modified: tasks/mm0/src/init.c modified: tasks/mm0/src/task.c modified: tools/ksym_to_lds.py modified: tools/l4-qemu
