+  [ Jurij Smakov ]
+  * [sparc] Switch to gcc-4.1 as it produces a working kernel,
+    while gcc-4.0 does not. No ABI bump neccessary, because
+    2.6.17-1 sparc binaries never made it to the archive.
+  * [sparc32] Add sparc32-iotlb.patch to fix DMA errors on sparc32.
+  * Add myself to uploaders.

+From: Bob Breuer <breuerr at mc.net>
+To: sparclinux at vger.kernel.org
+Subject: [PATCH] sparc32: fix iommu_flush_iotlb end address
+
+Fix the calculation of the end address when flushing iotlb entries to
+ram.  This bug has been a cause of esp dma errors, and it affects
+HyperSPARC systems much worse than SuperSPARC systems.
+
+Signed-off-by: Bob Breuer <breuerr at mc.net>
+---
+
+Just in case it's not obvious from the patch as to how the dma was
+broken:  Each dma mapping sets up iopte entries for the iommu, and the
+iommu only looks in main memory for the iopte entries.  If there is a
+group of iopte entries that are smaller than a page in size, but
+straddle a page boundary, the broken code would fail to flush the last
+page to ram.
