tracing, Text Edit Lock - kprobes architecture independent support, nommu fix
Impact: build fix on SH !CONFIG_MMU Stephen Rothwell reported this linux-next build failure on the SH architecture: kernel/built-in.o: In function `disable_all_kprobes': kernel/kprobes.c:1382: undefined reference to `text_mutex' [...] And observed: | Introduced by commit 4460fdad85becd569f11501ad5b91814814335ff ("tracing, | Text Edit Lock - kprobes architecture independent support") from the | tracing tree. text_mutex is defined in mm/memory.c which is only built | if CONFIG_MMU is defined, which is not true for sh allmodconfig. Move this lock to kernel/extable.c (which is already home to various kernel text related routines), which file is always built-in.
