* sched: INIT_PREEMPT_COUNTPeter Zijlstra2009-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | Pull the initial preempt_count value into a single definition site. Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

* parisc: ensure broadcast tlb purge runs single threadedHelge Deller2009-07-033-19/+30
| | | | | | | | | | | | The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock the kernel. The deadlocks only happened during I/O intensive loads and triggered pretty seldom, which is why this bug went so long unnoticed.

* parisc: fix "delay!" timer handlingGrant Grundler2009-07-031-35/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrote timer_interrupt() to properly handle the "delayed!" case. If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer. Tested on A500 (550 Mhz PA8600).

I think I have it right but recognize I might not. TODO: I wanted to use "do_div()" in order to get both remainder and value back with one division op. That should help with the latency alot but can be applied seperately from this patch. thanks, grant

* parisc: fix ldcw inline assemblerHelge Deller2009-07-031-2/+2
| | | | | | | | | | | | | | | | | | | There are two reasons to expose the memory *a in the asm: 1) To prevent the compiler from discarding a preceeding write to *a, and 2) to prevent it from caching *a in a register over the asm. The change has had a few days testing with a SMP build of 2.6.22.19 running on a rp3440. This patch is about the correctness of the __ldcw() macro itself. The use of the macro should be confined to small inline functions to try to limit the effect of clobbering memory on GCC's optimization of loads and stores.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(), and by defining it, the old arch_send_call_function_ipi is defined by the core code. We also take the chance to change send_IPI_mask() and use the new for_each_cpu() iterator. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
