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/xtensa-linux/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 498e47cd1d1f3e0a870a29d1b28093e64db52fd2 # make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_allmodconfig_xtensa-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_allmodconfig_xtensa-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux- help # make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_allmodconfig_xtensa-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux- olddefconfig # make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_allmodconfig_xtensa-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux- /kisskb/src/crypto/scompress.c: In function 'scomp_acomp_comp_decomp': /kisskb/src/crypto/scompress.c:174:38: error: unused variable 'dst_page' [-Werror=unused-variable] 174 \| struct page dst_page = sg_page(req->dst); \| ^~~~~~~~ cc1: all warnings being treated as errors make[4]: [/kisskb/src/scripts/Makefile.build:244: crypto/scompress.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:485: crypto] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/Makefile:1919: .] Error 2 make[1]: * [/kisskb/src/Makefile:240: __sub-make] Error 2 make: *** [Makefile:240: __sub-make] Error 2 Command 'make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_allmodconfig_xtensa-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/xtensa-linux/bin/xtensa-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allmodconfig_xtensa-gcc13 # Build took: 0:07:16.453250
