gxemul irq controller and timer "drivers"		  
2244 6371 d 16 h kebrt /branches/arm/kernel/arch/mips32/include/mm/ page has 16KB (ONE_FRAME used instead of FOUR_FRAMES)  
2243 6372 d 3 h kebrt /branches/arm/kernel/arch/arm32/ last_frame variable added (as in other archs), kernel page table created (not yet used)  
2242 6372 d 4 h kebrt /branches/arm/kernel/ ARM has 16kB first level page table, so PTL0..3_SIZE constants added to frame_alloc and all achitectures

2233 6375 d 4 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6375 d 5 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6375 d 8 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.		  
2230 6375 d 9 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console		  
2229 6375 d 11 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.		  
2228 6375 d 11 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6375 d 19 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6375 d 19 h decky /trunk/contrib/conf/ MIPS boot image has grown
