[PATCH] uml: cleanup unprofile expression and build infrastructure
*) Rather than duplicate in various buggy ways the application of
CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files),
centralize it in Makefile.rules. UNPROFILE_OBJS mustn't be listed in
USER_OBJS but are compiled as such.
I've also verified that unprofile didn't work in the current form, because we
set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong),
which is normally used by c_flags, but we also override c_flags for all
USER_OBJS, and there we don't call unprofile.
Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ.
We need to set c_flags (which is not a public Kbuild API) to clear a lot of
compilation flags like -nostdinc which Kbuild forces on everything.
*) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when
building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses
CFLAGS_anObj.o, like done by Kbuild.
*) Make c_flags apply to all targets having the same basename, rather than
listing .s, .i, .lst and .o, with the use (which I tested) of
$(USER_OBJS:.o=.%): c_flags = ...
and of
- $(obj)/unmap.c: _c_flags = ...
+ $(obj)/unmap.%: _c_flags = ...
