* fs: rename buffer trylockNick Piggin2008-08-049-13/+17
| | | | | | | | Like the page lock change, this also requires name change, so convert the raw test_and_set bitop to a trylock. Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* mm: rename page trylockNick Piggin2008-08-0420-59/+74
| | | | | | | | | | | | | | | Converting page lock to new locking bitops requires a change of page flag operation naming, so we might as well convert it to something nicer (!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked). This also facilitates lockdeping of page lock.

| * sparc64: Remove all cpumask_t local variables in xcall dispatch.David S. Miller2008-08-041-24/+9
| | | | | | | | | | | | | | | | | | All of the xcall delivery implementation is cpumask agnostic, so we can pass around pointers to const cpumask_t objects everywhere. The sad remaining case is the argument to arch_send_call_function_ipi(). Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Kill error_mask from hypervisor_xcall_deliver().David S. Miller2008-08-041-13/+7
| | | | | | | | | | | | | | | | It can eat up a lot of stack space when NR_CPUS is large. We retain some of it's functionality by reporting at least one of the cpu's which are seen in error state. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | Then modify all of the xcall dispatch implementations get passed and use this information. Now all of the xcall dispatch implementations do not need to be mindful of details such as "is current cpu in the list?" and "is cpu online?" Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | The idea is that we'll use this cpu list array and mondo block even for non-hypervisor platforms. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Make smp_cross_call_masked() take a cpumask_t pointer.David S. Miller2008-08-041-7/+11
| | | | | | | | | | | | | | | | | | | | Ideally this could be simplified further such that we could pass the pointer down directly into the xcall_deliver() implementation. But if we do that we need to do the "cpu_online(cpu)" and "cpu != self" checks down in those functions. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Directly call xcall_deliver() in smp_start_sync_tick_client.David S. Miller2008-08-041-4/+2
| | | | | | | | | | | | We know the cpu is online and not the current cpu here. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Call xcall_deliver() directly in some cases.David S. Miller2008-08-041-23/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For these cases the callers make sure: 1) The cpus indicated are online. 2) The current cpu is not in the list of indicated cpus. Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.

I don't think there is "common" definition for these values. Values are chosen by consideration of followings... P1 is 0. perhaps no question. P2 is from hardware manual, which says no-cache area starts at 20000000. It means that P? space size=20000000. P3 is P2+size since asm/ptrace.h uses P3 as a end of P2.
