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 # Cc: Borislav Petkov # Cc: Fenghua Yu # Cc: Luis Chamberlain # Cc: stable@kernel.org # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 f5ae2ea6347a308cfe91f53b53682ce635497d0d # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- allnoconfig # make -s -j 32 ARCH=mips O=/kisskb/build/linus_mips-allnoconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/vdso/Makefile:62: MIPS VDSO requires binutils >= 2.25 /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] FIT description: Linux 5.5.0-rc6+ Created: Thu Jan 16 18:34:12 2020 Image 0 (kernel@0) Description: Linux 5.5.0-rc6+ Created: Thu Jan 16 18:34:12 2020 Type: Kernel Image Compression: gzip compressed Data Size: 651425 Bytes = 636.16 KiB = 0.62 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x80223640 Hash algo: sha1 Hash value: ab292f1102b748430466de3d8043e73024b635a3 Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Completed OK # rm -rf /kisskb/build/linus_mips-allnoconfig_mips # Build took: 0:00:18.044461
