2502 6218 d 23 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.		  
2501 6218 d 23 h jermar /trunk/kernel/generic/ Add explicit type for an AVL tree key.
Add function to walk an AVL tree using a supplied walker.		  
2500 6219 d 1 h jermar /trunk/kernel/ Make the kernel compile again after integrating the AVL tree.
Integrate with tests, add the AVL tree implementation author into AUTHORS.		  
2499 6219 d 1 h jermar /trunk/kernel/ Import the AVL tree implementation from the RCU branch.  
2495 6235 d 21 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2494 6236 d 16 h jermar /trunk/kernel/generic/ Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.		  
2493 6236 d 20 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2492 6241 d 19 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2491 6241 d 21 h jermar /trunk/uspace/ Fix two minor bugs in uspace's make clean.  
2490 6243 d 20 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2489 6243 d 22 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6245 d 15 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2487 6245 d 18 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2486 6245 d 18 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.		  
2485 6249 d 16 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6249 d 17 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6249 d 21 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.		  
2482 6250 d 12 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.		  
2481 6250 d 14 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.		  
2480 6254 d 23 h jermar /trunk/uspace/ Remove dummy presenter.  
2479 6254 d 23 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2478 6256 d 20 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.		  
2477 6257 d 14 h kebrt /trunk/kernel/arch/arm32/src/ fixes bug causing crash in tester 'thread1' test  
2476 6257 d 16 h jermar /trunk/ Cleanup.  
2475 6257 d 16 h jermar /trunk/uspace/rd/ Improve the rd task (not tested):
- allow more connections
- support write operation
- support concurrent requests
- sanity checks
- add comments

Please review.		  
2473 6259 d 15 h jermar /trunk/ Bump version to 0.2.0.5 (Twilight).  
2472 6260 d 17 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)		  
2471 6260 d 17 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2470 6264 d 15 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().		  
2469 6264 d 17 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.		  
2468 6264 d 18 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.		  
2467 6264 d 19 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6269 d 22 h jermar /trunk/ Merge arm32 into trunk.  
2462 6271 d 16 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.		  
2460 6271 d 17 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.		  
2459 6271 d 20 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.		  
2458 6271 d 20 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.		  
2457 6271 d 20 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2455 6272 d 15 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6272 d 15 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
