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/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 e99332e7b4cda6e60f5b5916cf9943a79dbef902 # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /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/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1037:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:665:16: warning: 'gapstart' 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] Completed OK # rm -rf /kisskb/build/linus_x86_64-allnoconfig_x86_64-gcc4.6 # Build took: 0:00:16.791534
