From: Jeff Kirsher <jeffrey.t.kirs...@intel.com> ------------------- This is a commit scheduled for the next v2.6.34 longterm release. http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git If you see a problem with using this for longterm, please comment. -------------------
commit e2faeec2de9e2c73958e6ea6065dde1e8cd6f3a2 upstream. The checksum field in the EEPROM on HPPA is really not a checksum but a signature (0x16d6). So allow 0x16d6 as the matching checksum on HPPA systems. This issue is present on longterm/stable kernels, I have verified that this patch is applicable back to at least 2.6.32.y kernels. v2- changed ifdef to use CONFIG_PARISC instead of __hppa__ CC: Guy Martin <gms...@tuxicoman.be> CC: Rolf Eike Beer <eike-ker...@sf-tec.de> CC: Matt Turner <matts...@gmail.com> Reported-by: Mikulas Patocka <miku...@artax.kerlin.mff.cuni.cz> Signed-off-by: Jeff Kirsher <jeffrey.t.kirs...@intel.com> Acked-by: Jesse Brandeburg <jesse.brandeb...@intel.com> Signed-off-by: David S.
