Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread.

/kernel/trunk/
CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().

Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.

/kernel/trunk/generic/src/
Remove extra before_thread_runs() calls.

* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.

/kernel/trunk/generic/
Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.

Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.

/kernel/trunk/generic/src/proc/
Correct sleeping on memory allocation during FPU lazy switch.
906
6662 d 7 h
palkovsky
/kernel/trunk/
Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared
