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 4460fdad85 ("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.
