3156 5857 d 17 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.  
3153 5857 d 21 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3149 5857 d 21 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3129 5862 d 15 h svoboda /branches/dynload/ initial ia64 support in iloader (broken)  
3009 5878 d 13 h svoboda /branches/dynload/ Merged latest trunk changes into dynload  
2986 5882 d 19 h svoboda /branches/dynload/kernel/generic/src/mm/ Declare old_frame as uintptr_t instead of int  
2985 5882 d 20 h svoboda /branches/dynload/ Fix as_area_change_flags() and use it in elf_loader.c  
2984 5882 d 21 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2927 5890 d 1 h decky /branches/dynload/ added dynload branch  
2745 5967 d 23 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5988 d 20 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2712 5993 d 20 h decky /trunk/kernel/ prettyprint output  
2647 6040 d 16 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 6119 d 0 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2467 6226 d 17 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2222 6292 d 14 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2183 6295 d 18 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.
