Even if they only have one # single callsite - it looks like gcc may have decided that the code was # unlikely, and not worth inlining. # # The code generation difference is harmless, but caused a few new section # mismatch errors, since the (now no longer inlined) function wasn't in # the __init section, but called other init functions: # # Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem() # Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap() # Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap() # # So add the appropriate __init annotation to make modpost not complain. # In both cases there were trivially just a single callsite from another # __init function. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 e99332e7b4cda6e60f5b5916cf9943a79dbef902 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:471:21: note: 'pdeo' was declared here /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] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here /kisskb/src/fs/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:4774:23: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/namei.c: In function 'handle_dots': /kisskb/src/fs/namei.c:1805:10: warning: 'inode' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/namei.c:1805:10: warning: 'seq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update.isra.93': /kisskb/src/fs/io_uring.c:6687:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x589fc4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x589fc4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x589fc4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x57997c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x589fc4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.7.0-rc4-15527-ge99332e7b Created: Mon May 11 00:32:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2768340 Bytes = 2703.46 KiB = 2.64 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.7.0-rc4-15527-ge99332e7b Created: Mon May 11 00:32:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2801598 Bytes = 2735.94 KiB = 2.67 MiB Load Address: 00600000 Entry Point: 006019cc Image Name: Linux-5.7.0-rc4-15527-ge99332e7b Created: Mon May 11 00:32:13 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2801633 Bytes = 2735.97 KiB = 2.67 MiB Load Address: 00600000 Entry Point: 00601758 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:44.566673
