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/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 f5ae2ea6347a308cfe91f53b53682ce635497d0d # < make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- m5272c3_defconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/include/linux/string.h:20, from /kisskb/src/include/linux/bitmap.h:9, from /kisskb/src/include/linux/cpumask.h:12, from /kisskb/src/include/linux/rcupdate.h:31, from /kisskb/src/include/linux/rculist.h:11, from /kisskb/src/include/linux/dcache.h:7, from /kisskb/src/include/linux/fs.h:8, from /kisskb/src/fs/ext2/ext2.h:14, from /kisskb/src/fs/ext2/ioctl.c:11: /kisskb/src/fs/ext2/ioctl.c: In function 'ext2_ioctl': /kisskb/src/arch/m68k/include/asm/string.h:72:25: warning: '__builtin_memcpy' forming offset [3, 4] is out of the bounds [0, 2] of object '__gu_val' with type 'short unsigned int' [-Warray-bounds] #define memcpy(d, s, n) __builtin_memcpy(d, s, n) ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/m68k/include/asm/uaccess_no.h:86:2: note: in expansion of macro 'memcpy' memcpy((void ) &__gu_val, ptr, sizeof ((ptr))); \ ^~~~~~ /kisskb/src/fs/ext2/ioctl.c:123:7: note: in expansion of macro 'get_user' if (get_user(rsv_window_size, (int __user )arg)) ^~~~~~~~ In file included from /kisskb/src/arch/m68k/include/asm/uaccess.h:3, from /kisskb/src/include/linux/uaccess.h:11, from /kisskb/src/include/linux/crypto.h:21, from /kisskb/src/include/crypto/hash.h:11, from /kisskb/src/include/linux/uio.h:10, from /kisskb/src/include/linux/socket.h:8, from /kisskb/src/include/linux/compat.h:15, from /kisskb/src/fs/ext2/ioctl.c:15: /kisskb/src/arch/m68k/include/asm/uaccess_no.h:74:15: note: '__gu_val' declared here typeof(x) __gu_val = 0; \ ^~~~~~~~ /kisskb/src/fs/ext2/ioctl.c:123:7: note: in expansion of macro 'get_user' if (get_user(rsv_window_size, (int __user )arg)) ^~~~~~~~ /kisskb/src/drivers/net/ethernet/freescale/fec_main.c: In function 'fec_restart': /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:915:6: warning: unused variable 'val' [-Wunused-variable] u32 val; ^~~ /kisskb/src/drivers/net/ethernet/freescale/fec_main.c: In function 'fec_get_mac': /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:1643:28: warning: unused variable 'pdata' [-Wunused-variable] struct fec_platform_data pdata = dev_get_platdata(&fep->pdev->dev); ^~~~~ In file included from /kisskb/src/arch/m68k/include/asm/atomic.h:7, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/linux/spinlock.h:445, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/include/linux/stat.h:19, from /kisskb/src/include/linux/module.h:13, from /kisskb/src/net/core/filter.c:20: /kisskb/src/net/core/filter.c: In function 'bpf_clear_redirect_map': /kisskb/src/arch/m68k/include/asm/cmpxchg.h:137:3: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr)))__cmpxchg_local_generic((ptr), (unsigned long)(o),\ ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (unsigned long)(n), sizeof(*(ptr)))) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/include/asm-generic/cmpxchg.h:106:28: note: in expansion of macro 'cmpxchg_local' #define cmpxchg(ptr, o, n) cmpxchg_local((ptr), (o), (n)) ^~~~~~~~~~~~~ /kisskb/src/net/core/filter.c:3604:4: note: in expansion of macro 'cmpxchg' cmpxchg(&ri->map, map, NULL); ^~~~~~~ Completed OK # rm -rf /kisskb/build/linus_m5272c3_defconfig_m68k # Build took: 0:00:29.469386
