This avoids the accidental symbol # conflict. # # However, in some cases, we build an external module to provide a # different version/variant of the in-kernel module, overriding the # same set of exported symbols. # # At least, there is one use-case in the upstream code; # tools/testing/nvdimm/libnvdimm.ko replaces drivers/nvdimm/libnvdimm.ko # in order to link it against mocked version of core kernel symbols. # # Now, this emits a lots of 'exported twice' warnings: # # https://lkml.org/lkml/2019/10/31/627 # # To suppress those, add a new option KBUILD_MULTI_EXPORT_NO_WARN. # # If you intentionally override the existing symbols, you can pass it # from the command line: # # make M=tools/testing/nvdimm KBUILD_MULTI_EXPORT_NO_WARN=1 # # Or, more conveniently, you can add it to the module Makefile, so # you can still do: # # make M=tools/testing/nvdimm # # without sprinkling the warnings. # # Reported-by: Jeff Moyer <jmoyer@redhat.com> # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # Tested-by: Jeff Moyer <jmoyer@redhat.com> # < /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 aa9581108f498991e309c4a90b1af0805d2e41b5 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/kbuild_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 24 ARCH=powerpc O=/kisskb/build/kbuild_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-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/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x53b780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53b780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53b780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53b780) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x52b10c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.4.0-rc6-gaa9581108f49 Created: Thu Nov 7 22:51:01 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2624657 Bytes = 2563.14 KiB = 2.50 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.4.0-rc6-gaa9581108f49 Created: Thu Nov 7 22:51:01 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2658330 Bytes = 2596.03 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006019cc Image Name: Linux-5.4.0-rc6-gaa9581108f49 Created: Thu Nov 7 22:51:01 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2657564 Bytes = 2595.28 KiB = 2.53 MiB Load Address: 00600000 Entry Point: 00601758 Completed OK # rm -rf /kisskb/build/kbuild_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:53.195713
