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-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 f5ae2ea6347a308cfe91f53b53682ce635497d0d # < make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 8 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:38: LSE atomics not supported by binutils /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:14, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_dma_rx_submit': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1352:16: note: 'flags' was declared here unsigned long flags; ^ Completed OK # rm -rf /kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 # Build took: 0:10:45.466358
