2183 6424 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.		  
2118 6483 d 3 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2089 6491 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2087 6492 d 0 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6501 d 21 h jermar /trunk/ (c) versus (C)  
2068 6509 d 5 h jermar /trunk/kernel/ Formatting and indentation fixes.  
2067 6512 d 3 h jermar /trunk/kernel/ More formatting changes.  
2040 6536 d 4 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2030 6537 d 6 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6627 d 1 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6628 d 4 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6643 d 7 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1787 6691 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6699 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6713 d 5 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6717 d 6 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6719 d 6 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6720 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1576 6728 d 22 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1571 6729 d 0 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
