2008-12-28	swiotlb: add hwdev to swiotlb_phys_to_bus() / swiotlb_sg_to_bus()	Jeremy Fitzhardinge	1	-1/+2
	Impact: extend functions with a (yet unused) parameter, update callsites Some architectures need it - in preparation for highmem swiotlb. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-17	swiotlb: add arch hook to force mapping	Ian Campbell	1	-0/+2
	Impact: generalize the sw-IOTLB range checks Some architectures require special rules to determine whether a range needs mapping or not. This adds a weak function for architectures to override.

2008-12-17	swiotlb: allow architectures to override phys<->bus<->phys conversions	Ian Campbell	1	-0/+3
	Impact: generalize phys<->bus<->phys conversions in the swiotlb code Architectures may need to override these conversions. Implement a __weak hook point containing the default implementation.

2008-12-16	swiotlb: move some definitions to header	Ian Campbell	1	-0/+14
	Impact: cleanup Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-16	swiotlb: allow architectures to override swiotlb pool allocation	Jeremy Fitzhardinge	1	-0/+3
	Impact: generalize swiotlb allocation code Architectures may need to allocate memory specially for use with the swiotlb. Create the weak function swiotlb_alloc_boot() and swiotlb_alloc() defaulting to the current behaviour.

2008-10-16	introduce generic header file for the software IO/TLB	Joerg Roedel	1	-0/+83
	A series of patches introduce a generic header file for the software IO/TLB implementation in lib/swiotlb.c. Currently each architecture using this code defines the prototypes itself. The prototypes are moved to include/linux/swiotlb.h and this file is included in architecture specific code for X86 and IA64. This patch: Create include/linux/swiotlb.h file which contains all function prototypes for the lib/swiotlb.c file. (akpm: the dependent patches will be trickled through arch trees) Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
