* [SPARC]: Kill __irq_itoa().David S. Miller2006-06-205-32/+0
| | | | | | | | | | | | | | | | | | This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: bp->pil can never be zeroDavid S. Miller2006-06-201-14/+13
| | | | | | | | Only pil0_dummy_bucket had a pil of zero and we just killed that off, so we can delete all special case code that used bp->pil==0 as a way to identify a dummy bucket. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Send all device interrupts via one PIL.David S. Miller2006-06-206-130/+87
| | | | | | | | | | | | | | | | | | This is the first in a series of cleanups that will hopefully allow a seamless attempt at using the generic IRQ handling infrastructure in the Linux kernel. Define PIL_DEVICE_IRQ and vector all device interrupts through there. Get rid of the ugly pil0_dummy_{bucket,desc}, instead vector the timer interrupt directly to a specific handler since the timer interrupt is the only event that will be signaled on PIL 14. The irq_worklist is now in the per-cpu trap_block[]. Signed-off-by: David S. Miller <davem@davemloft.net>

| * [PATCH] Fix BCM1480 doubled process accounting times.[MIPS] James E Wilson2006-06-191-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running a UP kernel on a bcm1480 board, I get nonsensical timing results, like this: release@unknown:~/tmp$ time ./a.out real 0m22.906s user 0m45.792s sys 0m0.010s According to my watch, this program took 23 seconds to run, so the real time clock is OK. It is process accounting that is broken. I tracked this down to a problem with the function bcm1480_timer_interrupt in the file sibyte/bcm1480/time.c. This function calls ll_timer_interrupt for cpu0, and ll_local_timer_interrupt for all cpus. However, both of these functions do process accounting. Thus processes running on cpu0 end up with doubled times. This is very obvious in a UP kernel where all processes run on cpu0. The correct way to do this is to only call ll_local_timer interrupt if this is not cpu0. This can be seen in the mips-board/generic/time.c file, and also in the sibyte/sb1250/time.c file, both of which handle this correctly. I fixed the bcm1480/time.c file by copying over the correct code from the sb1250/time.c file. With this fix, I now get sensible results. release@unknown:~/tmp$ time ./a.out real 0m22.903s user 0m22.894s sys 0m0.006s Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
