3156	5836 d 0 h	svoboda	/branches/dynload/kernel/generic/src/mm/	Separate page removal and insertion in as_area_change_flags() so that usage of old and new mapping cannot interleave.

3149	5836 d 5 h	svoboda	/branches/dynload/	Merge trunk changes up to r3071 into dynload (broken)
3129	5840 d 22 h	svoboda	/branches/dynload/	initial ia64 support in iloader (broken)
2986	5861 d 2 h	svoboda	/branches/dynload/kernel/generic/src/mm/	Declare old_frame as uintptr_t instead of int
2985	5861 d 3 h	svoboda	/branches/dynload/	Fix as_area_change_flags() and use it in elf_loader.c
2984	5861 d 5 h	svoboda	/branches/dynload/	Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.
2927	5868 d 8 h	decky	/branches/dynload/	added dynload branch
2745	5946 d 6 h	decky	/trunk/	code cleanup (mostly signed/unsigned) allow extra compiler warnings
2647	6018 d 23 h	jermar	/trunk/kernel/generic/src/mm/	Fix a bug in anonymous address space area sharing. Call the backend's share function only if the source area is not already shared. Otherwise increment the sh_info refcount. Without this fix, the kernel will try to recreate the pagemap if three and more address space areas attempt to share the same data.
2556	6097 d 7 h	jermar	/trunk/kernel/generic/	Rename as_get_size() to as_area_get_size() and add a doxygen comment.
2183	6274 d 2 h	jermar	/trunk/kernel/generic/	Continue to de-oversynchronize the kernel. - replace as->refcount with an atomic counter; accesses to this reference counter are not to be done when the as->lock mutex is held; this gets us rid of mutex_lock_active(); Remove the possibility of a deadlock between TLB shootdown and asidlock. - get rid of mutex_lock_active() on as->lock - when locking the asidlock spinlock, always do it conditionally and with preemption disabled; in the unsuccessful case, enable interrupts and try again - there should be no deadlock between TLB shootdown and the as->lock mutexes - PLEASE REVIEW !!! Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
2170	6278 d 19 h	jermar	/trunk/kernel/	Simplify synchronization in as_switch(). The function was oversynchronized, which was causing deadlocks on the address space mutex. Now, address spaces can only be switched when the asidlock is held. This also protects stealing of ASIDs. No other synchronization is necessary.
