Hrm, so we should move the text_mutex in a obj-y file. It's not clear to
me which of mm/Makefile would be the best choice :
obj-y := bootmem.o filemap.o mempool.o oom_kill.o fadvise.o \
maccess.o page_alloc.o page-writeback.o pdflush.o \
readahead.o swap.o truncate.o vmscan.o shmem.o \
prio_tree.o util.o mmzone.o vmstat.o backing-dev.o \
page_isolation.o mm_init.o $(mmu-y)
Or maybe we add a new file, or put this in kernel/*.c. Suggestions ?
