The description should be clear enough: "crypto: aesni-intel - Fixed build error on x86-32". Here is the link to the patch: <http://git.kernel.org/?p=linux/kernel/git/herbert/cryptodev-2.6.git;a=patch;h=559ad0ff1368baea14dbc3207d55b02bd69bda4b>. Please apply it on top of your linux-next build. > I'm using the linux-next tarball of 20111129. > However, your s/__x86_64__/CONFIG_X86_64/ patch was applied, so I dropped it. Well I doubt it. The patch was made on top of 559ad0ff so it should have failed to apply in your tree since obviously 559ad0ff is missing. > new output file: > http://oss.oracle.com/~rdunlap/doc/cry4.out Same bug: 559ad0ff is still missing.
