1583 6538 d 4 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1502 6541 d 3 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1460 6543 d 3 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1416 6549 d 5 h jermar /kernel/trunk/generic/ Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.		  
1380 6553 d 20 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1375 6555 d 3 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1156 6595 d 1 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1139 6604 d 21 h jermar /kernel/trunk/generic/include/ Fix comments.  
1117 6611 d 18 h jermar /kernel/trunk/generic/ Improved futexes. (kernel part)  
1109 6612 d 17 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1104 6612 d 22 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1100 6614 d 19 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
788 6657 d 21 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
625 6709 d 23 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
623 6710 d 5 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
557 6718 d 2 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
553 6718 d 17 h palkovsky /kernel/trunk/generic/include/synch/ Fix of compiling without SMP.  
552 6718 d 17 h palkovsky /kernel/trunk/ Named spinlocks  
534 6720 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6720 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
