[IA64] Convert ia64 to use int-ll64.h

2009-06-17T16:33:49Z

It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling. [Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use u64 for start/end rather than unsigned long] Signed-off-by: Matthew Wilcox Signed-off-by: Tony Luck

page allocator: do not check NUMA node ID when the caller knows the node is valid

2009-06-17T02:47:32Z

Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

[IA64] remove obsolete irq_desc_t typedef

2009-06-15T21:34:31Z

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users and remove the typedef. Signed-off-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Tony Luck

irq: change ->set_affinity() to return status

2009-04-28T10:21:16Z

according to Ingo, change set_affinity() in irq_chip should return int, because that way we can handle failure cases in a much cleaner way, in the genirq layer. v2: fix two typos [ Impact: extend API ] Signed-off-by: Yinghai Lu Cc: Andrew Morton Cc: Suresh Siddha Cc: "Eric W.
