3200 5840 d 0 h svoboda /trunk/kernel/arch/ppc32/src/ Remove buggy assembler memsetb function, call generic C _memsetb instead. Fixes kconsole panic when uspace klog is enabled and memsetb() called from klog_update()  
/trunk/kernel/arch/ppc32/src/asm.S
3198 5841 d 17 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
/trunk/boot/arch/mips32/loader/Makefile
/trunk/kernel/generic/include/config.h
3194 5842 d 1 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.

3189 5847 d 15 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.		  
/trunk/kernel/arch/ppc32/src/asm.S
3188 5849 d 13 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
/trunk/kernel/generic/src/mm/frame.c
3187 5849 d 18 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 5849 d 18 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.

/trunk/kernel/generic/src/mm/frame.c
3184 5850 d 21 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/ipc/ipc.c
3183 5850 d 22 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.

3180 5852 d 3 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
/trunk/kernel/generic/src/mm/slab.c
3179 5852 d 19 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/amd64/Makefile.inc
/trunk/kernel/arch/ia32/Makefile.inc
3175 5854 d 0 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 5854 d 15 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 5854 d 15 h jermar /trunk/kernel/ Frame pointers will make debugging much easier.  
/trunk/kernel/Makefile
3167 5855 d 3 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 5855 d 15 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

/trunk/uspace/lib/libc/arch/amd64/include/atomic.h
3162 5856 d 15 h jermar /trunk/ The first argument to atomic_add() is read-write. (mips32)

3145 5858 d 4 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.
