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/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 498e47cd1d1f3e0a870a29d1b28093e64db52fd2 # make -s -j 160 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- se7619_defconfig # < make -s -j 160 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 160 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 160 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/mm/cache-sh2.c:85:13: warning: no previous prototype for 'sh2_cache_init' [-Wmissing-prototypes] 85 \| void __init sh2_cache_init(void) \| ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:76:13: warning: no previous prototype for 'kmap_coherent_init' [-Wmissing-prototypes] 76 \| void __init kmap_coherent_init(void) \| ^~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:80:7: warning: no previous prototype for 'kmap_coherent' [-Wmissing-prototypes] 80 \| void kmap_coherent(struct page page, unsigned long addr) \| ^~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:86:6: warning: no previous prototype for 'kunmap_coherent' [-Wmissing-prototypes] 86 \| void kunmap_coherent(void kvaddr) \| ^~~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/init.c:99:29: warning: no previous prototype for 'l2_cache_init' [-Wmissing-prototypes] 99 \| void __attribute__ ((weak)) l2_cache_init(void) \| ^~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/return_address.c:49:7: warning: no previous prototype for 'return_address' [-Wmissing-prototypes] 49 \| void return_address(unsigned int depth) \| ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/sys_sh.c:58:16: warning: no previous prototype for 'sys_cacheflush' [-Wmissing-prototypes] 58 \| asmlinkage int sys_cacheflush(unsigned long addr, unsigned long len, int op) \| ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/traps_32.c:735:6: warning: no previous prototype for 'per_cpu_trap_init' [-Wmissing-prototypes] 735 \| void per_cpu_trap_init(void) \| ^~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/hw_breakpoint.c:135:5: warning: no previous prototype for 'arch_bp_generic_fields' [-Wmissing-prototypes] 135 \| int arch_bp_generic_fields(int sh_len, int sh_type, \| ^~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_se7619_defconfig_sh4-gcc13 # Build took: 0:01:16.846505
