Upstream commit e66eed651fd18a961f11cda62f3b5286c8cc4f9f "list: remove prefetching from regular list iterators" removed <linux/prefetch.h> from <linux/list.h> very early in the v3.0 dev cycle (v2.6.39-2-ge66eed6), thereby causing build failures when it exposed the implicit prefetch users in parisc. Reported-by: David Rientjes <rientjes@xxxxxxxxxx> Reported-by: WANG Cong <xiyou.wangcong@xxxxxxxxx> Signed-off-by: Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx> --- [ The parisc defconfig has been failing to build everywhere since last May! http://kisskb.ellerman.id.au/kisskb/target/2059/ And this one liner fix https://lkml.org/lkml/2011/10/15/121 was reported last Oct, and again http://www.spinics.net/lists/linux-parisc/msg03945.html in early Feb. So, now with a clear reasoning in the commit header as to why it fails, can we finally get this in tree please? ] diff --git a/drivers/parisc/iommu-helpers.h b/drivers/parisc/iommu-helpers.h index a9c46cc..8c33491 100644 --- a/drivers/parisc/iommu-helpers.h +++ b/drivers/parisc/iommu-helpers.h @@ -1,3 +1,5 @@ +#include <linux/prefetch.h> + /** * iommu_fill_pdir - Insert coalesced scatter/gather chunks into the I/O Pdir. * @ioc: The I/O Controller. -- 1.7.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
