2.6.29-stable review patch. If anyone has any objections, please let us know. ------------------ From: Peter Korsgaard commit dbf8c11f821b6ff83302c34f2403b4f7231f50ae upstream. Commit 5b7f3a50 (fix dataflash 64-bit divisions) unfortunately introduced a typo. Erase addr and len were swapped in the pageaddr calculation, causing the wrong sectors to get erased.
