And on 64-bit architectures it causes warnings. # # Admittedly, 64-bit architectures with ISA are basically dead - I think # the only example of this is alpha, and nobody would ever use the dmascc # driver there. But hey, the fix is easy enough, the end result is # cleaner, and it's yet another configuration that now builds without # warnings. # # If somebody actually uses this driver on an alpha and this fixes it for # you, please email me. Because that is just incredibly bizarre. # # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux-ld --version # < git log --format=%s --max-count=1 bc1abb9e55cedaeac4602426f8fc83fb3a5b1c35 # < make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux- axs103_smp_defconfig /kisskb/src/arch/arc/Makefile:26: ** WARNING ** CONFIG_ARC_TUNE_MCPU flag '' is unknown, fallback to '' # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # < make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux- help /kisskb/src/arch/arc/Makefile:26: ** WARNING ** CONFIG_ARC_TUNE_MCPU flag '' is unknown, fallback to '' # make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux- olddefconfig /kisskb/src/arch/arc/Makefile:26: ** WARNING ** CONFIG_ARC_TUNE_MCPU flag '' is unknown, fallback to '' # make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux- /kisskb/src/arch/arc/Makefile:26: ** WARNING ** CONFIG_ARC_TUNE_MCPU flag '' is unknown, fallback to '' In file included from /kisskb/src/arch/arc/include/asm/io.h:233, from /kisskb/src/include/linux/io.h:13, from /kisskb/src/include/linux/irq.h:20, from /kisskb/src/include/asm-generic/hardirq.h:17, from ./arch/arc/include/generated/asm/hardirq.h:1, from /kisskb/src/include/linux/hardirq.h:11, from /kisskb/src/include/linux/interrupt.h:11, from /kisskb/src/arch/arc/kernel/asm-offsets.c:8: /kisskb/src/include/asm-generic/io.h:1059:21: error: redefinition of 'pci_iounmap' 1059 | #define pci_iounmap pci_iounmap | ^~~~~~~~~~~ /kisskb/src/include/asm-generic/io.h:1060:20: note: in expansion of macro 'pci_iounmap' 1060 | static inline void pci_iounmap(struct pci_dev *dev, void __iomem *p) | ^~~~~~~~~~~ In file included from /kisskb/src/include/asm-generic/io.h:19, from /kisskb/src/arch/arc/include/asm/io.h:233, from /kisskb/src/include/linux/io.h:13, from /kisskb/src/include/linux/irq.h:20, from /kisskb/src/include/asm-generic/hardirq.h:17, from ./arch/arc/include/generated/asm/hardirq.h:1, from /kisskb/src/include/linux/hardirq.h:11, from /kisskb/src/include/linux/interrupt.h:11, from /kisskb/src/arch/arc/kernel/asm-offsets.c:8: /kisskb/src/include/asm-generic/pci_iomap.h:54:20: note: previous definition of 'pci_iounmap' was here 54 | static inline void pci_iounmap(struct pci_dev *dev, void __iomem *addr) | ^~~~~~~~~~~ make[2]: *** [/kisskb/src/scripts/Makefile.build:121: arch/arc/kernel/asm-offsets.s] Error 1 make[1]: *** [/kisskb/src/Makefile:1219: prepare0] Error 2 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/arc-linux/bin/arc-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_axs103_smp_defconfig_arc-gcc10 # Build took: 0:00:09.111645
