Hi, while compiling 3.15-rc6 for powerpc (gcc-4.8.1 crosscompiler on x86_64), a warning popped up:
WARNING: modpost: Found 1 section mismatch(es). Compiling with CONFIG_DEBUG_SECTION_MISMATCH=y gives: ----------------------------------- LD drivers/macintosh/built-in.o CC [M] fs/hfsplus/inode.o WARNING: drivers/macintosh/built-in.o(.data+0x184): Section mismatch in reference from the variable via_pmu_driver to the function .init.text:pmu_init() The variable via_pmu_driver references the function __init pmu_init() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console ----------------------------------- ...and, later on: ----------------------------------- LD drivers/built-in.o WARNING: drivers/built-in.o(.data+0x488c): Section mismatch in reference from the variable via_pmu_driver to the function .init.text:pmu_init() The variable via_pmu_driver references the function __init pmu_init() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console LINK vmlinux LD vmlinux.o MODPOST vmlinux.o WARNING: vmlinux.o(.data+0x1ff44): Section mismatch in reference from the variable via_pmu_driver to the function .init.text:pmu_init() The variable via_pmu_driver references the function __init pmu_init() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console ----------------------------------- This had been reported [0] by Geert for v3.3-rc1 back in 2012, and maybe the warning was always there, but I didn't notice it until now. Oh, and after everything has been built, this happens: ----------------------------------- INFO: Uncompressed kernel (size 0x6714a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) ----------------------------------- ...but I think this was always printed after compiling a kernel for PowerPC, I just just I should mention it (again [1]). Thanks, Christian.
