This tree is based on 2.6.32 and generally has all of the stable updates applied. Except those to the DRM subsystem, which was based on 2.6.33 and took updates from that upstream stable as long as that existed. It will continue to add patches to the DRM subsystem as long as they are valid according to the stable update rules (Documentation/stable_kernel_rules.txt). DRM patches for this tree should be sent to kernel-team@lists.ubuntu.com. This release contains patches from upstream 2.6.32.31, but dropped any patches to the DRM subsystem. The updated 2.6.32.y-drm33.z tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git and can be browsed through git web via: http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=summary -Stefan ------ * Revert "swiotlb: fix wrong panic" * Linux 2.6.32.31 Makefile | 2 +- lib/swiotlb.c | 6 ++---- 2 files changed, 3 insertions(+), 5 deletions(-) diff --git a/Makefile b/Makefile index 0789e7c..ddc0ce4 100644 --- a/Makefile +++ b/Makefile @@ -1,7 +1,7 @@ VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 32 -EXTRAVERSION = .30+drm33.14 +EXTRAVERSION = .31+drm33.14 NAME = Man-Eating Seals of Antiquity # *DOCUMENTATION* diff --git a/lib/swiotlb.c b/lib/swiotlb.c index 7740ee8..ac25cd2 100644 --- a/lib/swiotlb.c +++ b/lib/swiotlb.c @@ -631,10 +631,8 @@ dma_addr_t swiotlb_map_page(struct device *dev, struct page *page, /* * Ensure that the address returned is DMA'ble */ - if (!dma_capable(dev, dev_addr, size)) { - swiotlb_tbl_unmap_single(dev, map, size, dir); - dev_addr = swiotlb_virt_to_bus(dev, io_tlb_overflow_buffer); - } + if (!dma_capable(dev, dev_addr, size)) + panic("map_single: bounce buffer is not DMA'ble"); return dev_addr; }
