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 120 ARCH=powerpc O=/kisskb/build/kbuild_44x_iss476-smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/iss476-smp_defconfig WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] # make -s -j 120 ARCH=powerpc O=/kisskb/build/kbuild_44x_iss476-smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:140:32: warning: 'levelspread[<U5780>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[<U5780>]' 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/block/blk-merge.c: In function 'blk_rq_map_sg': /kisskb/src/block/blk.h:78:50: warning: 'bvprv.bv_offset' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:466:42: note: 'bvprv.bv_offset' was declared here /kisskb/src/block/blk.h:81:12: warning: 'bvprv.bv_len' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:466:42: note: 'bvprv.bv_len' was declared here /kisskb/src/arch/powerpc/include/asm/io.h:802:22: warning: 'bvprv.bv_page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:466:42: note: 'bvprv.bv_page' was declared here /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 0x61b26c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x61b26c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Completed OK # rm -rf /kisskb/build/kbuild_44x_iss476-smp_defconfig_powerpc-gcc4.6 # Build took: 0:00:30.883904
