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/hppa-linux/bin/hppa64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/hppa-linux/bin/hppa64-linux-ld --version # < git log --format=%s --max-count=1 498e47cd1d1f3e0a870a29d1b28093e64db52fd2 # make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/hppa-linux/bin/hppa64-linux- generic-64bit_defconfig # < make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/hppa-linux/bin/hppa64-linux- help # make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/hppa-linux/bin/hppa64-linux- olddefconfig # make -s -j 32 ARCH=parisc64 O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/hppa-linux/bin/hppa64-linux- Completed OK # rm -rf /kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc13 # Build took: 0:02:21.109187
