3187 5876 d 8 h jermar /trunk/kernel/generic/src/mm/ Get rid of the infamous "Sleep not implemented" panic during low memory
condition. Use a condition variable to implement the sleep. As of now, the
condition is rather coarse and can cause that threads may sleep unnecessarily.
Needs to be fine tuned and based on the amount of memory available.		  
/trunk/kernel/generic/src/mm/frame.c
3186 5876 d 8 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.

3184 5877 d 11 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.

/trunk/kernel/generic/src/mm/slab.c
3179 5879 d 9 h jermar /trunk/kernel/ Introduce the notion of FPU_NO_CFLAGS and separate building of test/fpu
objects and building the rest of kernel objects. Now, amd64 and ia32 can
enable things such as SSE selectively for the test/fpu/*.

/trunk/kernel/arch/ia32/Makefile.inc
3175 5880 d 14 h jermar /trunk/kernel/generic/src/main/ Don't print anything before the kernel initializes the first THE
structure. This fixes a regression introduced in r3061. If anything
worked from r3061 until now, it was only due to luck. arm32 was not
that lucky when built with gcc 4.3.1.		  
/trunk/kernel/generic/src/main/main.c
3173 5881 d 5 h jermar /trunk/kernel/arch/ia32/ Don't build the ia32 kernel with MMX/SSE/3DNOW enabled. This was causing
problems with gcc 4.3.1 which generated MMX aided code in a context that
didn't allow this.		  
/trunk/kernel/arch/ia32/Makefile.inc
3172 5881 d 5 h jermar /trunk/kernel/ Frame pointers will make debugging much easier.  
/trunk/kernel/Makefile
3167 5881 d 17 h svoboda /trunk/kernel/arch/mips32/include/ Fix mips32 atomic_add() which would break build unless a constant was propagated into the second argument. (Specifically at -O0)  
/trunk/kernel/arch/mips32/include/atomic.h
3165 5882 d 5 h jermar /trunk/kernel/test/avltree/ Fix an off-by-one bug in avltree1 test and also declare an unused static
function as used. These two bugs were breaking building by gcc 4.3.1.		  
/trunk/kernel/test/avltree/avltree1.c
3164 5883 d 5 h jermar /trunk/ First argument of atomic functions is read-write (ia32).

3145 5884 d 18 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.

executable segment.

3140 5885 d 14 h jermar /trunk/kernel/arch/ia64/include/ Fix operands for fc_i().
