  "message": "[PATCH] swiotlb: make sure initial DMA allocations really are in DMA memory\n\nThis introduces a limit parameter to the core bootmem allocator; The new\nparameter indicates that physical memory allocated by the bootmem\nallocator should be within the requested limit.\n\nWe also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit,\nalloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit\nis the only api used for swiotlb.\n\nThe existing alloc_bootmem_low_pages() api could instead have been\nchanged and made to pass right limit to the core allocator.  But that\nwould make the patch more intrusive for 2.6.14, as other arches use\nalloc_bootmem_low_pages().  We may be done that post 2.6.14 as a\ncleanup.\n\nWith this, swiotlb gets memory within 4G for both x86_64 and ia64\narches.\n\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: Ravikiran G Thirumalai \u003ckiran@scalex86.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
