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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 aa9581108f498991e309c4a90b1af0805d2e41b5 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/fsp2_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x956ed4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xa00000) Image Name: Linux-5.4.0-rc6-gaa9581108f49 Created: Thu Nov 7 22:57:48 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 4203196 Bytes = 4104.68 KiB = 4.01 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 # Build took: 0:01:15.561526
