Image that was created something like this: # # iucode_tool --write-earlyfw=FOO.cpio microcode-files... # # However, when early-load Intel microcode is loaded from built-in # firmware BLOB using CONFIG_EXTRA_FIRMWARE= kernel config option, that # 16-byte alignment is not guaranteed. # # Fix this by forcing all built-in firmware BLOBs to 16-byte alignment. # # [ If we end up having other firmware with much bigger alignment # requirements, we might need to introduce some method for the firmware # to specify it, this is the minimal "just increase the alignment a bit # to account for this one special case" patch - Linus ] # # Signed-off-by: Jari Ruusu <jari.ruusu@gmail.com> # Cc: Borislav Petkov <bp@alien8.de> # Cc: Fenghua Yu <fenghua.yu@intel.com> # Cc: Luis Chamberlain <mcgrof@kernel.org> # Cc: stable@kernel.org # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 f5ae2ea6347a308cfe91f53b53682ce635497d0d # < make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allnoconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allnoconfig # make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allnoconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- Completed OK # rm -rf /kisskb/build/linus_xtensa-allnoconfig_xtensa # Build took: 0:00:12.917735
