[PATCH] uml: fix wall_to_monotonic initialization

2006-06-05T19:29:17+00:00

From: Jeff Dike 

Initialize wall_to_monotonic correctly.  This fixes a problem where sleeps
lasted about one secone less than they should.  This also called for a bit of
code restructuring, following a patch which Blaisorblade had been keeping.

[PATCH] uml: change timer initialization

2006-05-04T03:05:40+00:00

inet_init, which schedules, is called before the UML timer_init, which sets
up the timer.  The result is the interval timers being manipulated before
the appropriate signal handlers are established, causing unhandled timers.

This is fixed by making timer_init be called earlier.

[PATCH] uml: uml-makefile-nicer uses SYMLINK incorrectly

2006-05-02T01:17:45+00:00

Blaisorblade's uml-makefile-nicer makes a V=0 build say SYMLINK where
what's happening is really a LINK.

[PATCH] uml: export symbols added by GCC hardened

2006-05-02T01:17:45+00:00

GCC hardened introduces additional symbol refererences (for the canary and
friends), also in modules - add weak export_symbols for them.  We already
tested that the weak declaration creates no problem on both GCC's providing
the function definition and on GCC's which don't provide it.

[PATCH] uml: cleanup unprofile expression and build infrastructure

2006-05-02T01:17:45+00:00

*) 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 = ...
