x86-32: Pass the full resource data to ioremap()

2008-03-24T18:22:39Z

It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.

devres: implement pcim_iomap_regions_request_all()

2008-03-17T12:26:44Z

Some drivers need to reserve all PCI BARs to prevent other drivers misusing unoccupied BARs. pcim_iomap_regions_request_all() requests all BARs and iomap specified BARs. Signed-off-by: Tejun Heo Cc: Greg Kroah-Hartman Cc: Alan Cox Cc: Jeff Garzik Signed-off-by: Jeff Garzik

avoid endless loops in lib/swiotlb.c

2008-03-13T20:15:52Z

Commit 681cc5cd3efbeafca6386114070e0bfb5012e249 ("iommu sg merging: swiotlb: respect the segment boundary limits") introduced two possibilities for entering an endless loop in lib/swiotlb.c: - if max_slots is zero (possible if mask is ~0UL) - if the number of slots requested fits into a swiotlb segment, but is too large for the part of a segment which remains after considering offset_slots This fixes them Signed-off-by: Jan Beulich Cc: FUJITA Tomonori Cc: Andrew Morton Signed-off-by: Linus Torvalds

iommu: export iommu_is_span_boundary helper function

2008-03-05T00:35:17Z

iommu_is_span_boundary is used internally in the IOMMU helper (lib/iommu-helper.c), a primitive function that judges whether a memory area spans LLD's segment boundary or not. It's difficult to convert some IOMMUs to use the IOMMU helper but iommu_is_span_boundary is still useful for them. So this patch exports it. This is needed for the parisc iommu fixes.

kobject: properly initialize ksets

2008-03-04T22:47:05Z

kset_initialize was calling kobject_init_internal() which didn't initialize the kobject as well as kobject_init() was. So have kobject_init() call kobject_init_internal() and move the logic to initalize the kobject there. Cc: Kay Sievers Cc: Hannes Reinecke Signed-off-by: Greg Kroah-Hartman

x86: trivial printk optimizations

2008-02-09T22:24:09Z

In arch/x86/boot/printf.c gets rid of unused tail of digits: const char *digits = "0123456789abcdefghijklmnopqrstuvwxyz"; (we are using 0-9a-f only) Uses smaller/faster lowercasing (by ORing with 0x20) if we know that we work on numbers/digits. Makes strtoul smaller, and also we are getting rid of static const char small_digits[] = "0123456789abcdefx"; static const char large_digits[] = "0123456789ABCDEFX"; since this works equally well: static const char digits[16] = "0123456789ABCDEF"; Size savings: $ size vmlinux.org vmlinux text data bss dec hex filename 877320 112252 90112 1079684 107984 vmlinux.org 877048 112252 90112 1079412 107874 vmlinux It may be also a tiny bit faster because code has less branches now, but I doubt it is measurable.
