1016 6698 d 21 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6699 d 0 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.		  
1007 6699 d 0 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6699 d 11 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6699 d 12 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6699 d 12 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
993 6699 d 16 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.		  
990 6699 d 17 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6699 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support

982 6699 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
980 6699 d 22 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
979 6699 d 22 h vana /kernel/trunk/arch/ia64/ Itanium FPU context save/restore  
977 6699 d 22 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6700 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6700 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6700 d 1 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
962 6700 d 15 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.

958 6700 d 16 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
957 6700 d 16 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
955 6700 d 16 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6700 d 20 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
951 6700 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
947 6701 d 2 h vana /kernel/trunk/ Better purge page selection.  
945 6701 d 15 h vana /kernel/trunk/arch/ia64/
