When the code # just blindly uses cast to mix the two, it caused problems when # phys_addr_t isn't the same size as a pointer - notably on 32-bit # architectures with PHYS_ADDR_T_64BIT. # # The proper thing to do would probably be to use a union member, and not # have any casts, and make the 'mem' member be a union of 'mem.physaddr' # and 'mem.vaddr', based on 'memtype'. # # This is not that proper thing. This is just fixing the ugly casts to be # even uglier, but at least not cause build errors on 32-bit platforms # with 64-bit physical addresses. # # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: 576882ef5e7f ("uio: introduce UIO_MEM_DMA_COHERENT type") # Fixes: 7722151e4651 ("uio_pruss: UIO_MEM_DMA_COHERENT conversion") # Fixes: 019947805a8d ("uio_dmem_genirq: UIO_MEM_DMA_COHERENT conversion") # Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> # Cc: Chris Leech <cleech@redhat.com> # Cc: Nilesh Javali <njavali@marvell.com> # Cc: Christoph Hellwig <hch@lst.de> # Signed-off-by: Linus Torvalds <torvalds@linuxfoundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 498e47cd1d1f3e0a870a29d1b28093e64db52fd2 # make -s -j 160 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- 32r6_defconfig Using /kisskb/src/arch/mips/configs/generic_defconfig as base Merging /kisskb/src/arch/mips/configs/generic/32r6.config Merging /kisskb/src/arch/mips/configs/generic/eb.config ./.config.32r6_defconfig:95:warning: override: CPU_BIG_ENDIAN changes choice state Merging /kisskb/src/arch/mips/configs/generic/board-boston.config Merging /kisskb/src/arch/mips/configs/generic/board-marduk.config Merging /kisskb/src/arch/mips/configs/generic/board-ranchu.config Merging /kisskb/src/arch/mips/configs/generic/board-sead-3.config Merging /kisskb/src/arch/mips/configs/generic/board-virt.config .config:94:warning: override: CPU_BIG_ENDIAN changes choice state # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_32r6_defconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.17-178.5: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0: '#interrupt-cells' found, but node is not an interrupt provider /kisskb/src/arch/mips/boot/dts/img/boston.dts:136.23-177.6: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0/eg20t_bridge@1,0,0: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/img/boston.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' Completed OK # rm -rf /kisskb/build/linus_32r6_defconfig_mips-gcc13 # Build took: 0:01:40.424846
