3208 5880 d 23 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
/trunk/kernel/generic/include/mm/frame.h
/trunk/kernel/generic/src/mm/frame.c
3207 5880 d 23 h jermar /trunk/kernel/generic/ Introduce FRAME_LOW_16_GiB slab/frame allocator flag. When specified, the
allocators will not allocate memory above 16 GiB. Each architecture needs to
make sure not to merge zones from below and above 16 GiB. Allocations that
require memory below 16 GiB need to be altered to use this flag.

/trunk/kernel/generic/src/mm/frame.c
3206 5881 d 0 h jermar /trunk/kernel/generic/ Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it.

3205 5881 d 3 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.

3188 5893 d 20 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 5894 d 0 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 5894 d 0 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 5895 d 3 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 5895 d 4 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.

3180 5896 d 10 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
/trunk/kernel/generic/src/mm/slab.c
3175 5898 d 7 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.
