Yes, the arguments to # drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64', # but none of the values here are remotely relevant, and the compiler will # happily just do the type expansion. # # Of course, in a perfect world the compiler would also have just noticed # that all the values in question are tiny, and range analysis would have # shown that doing a 64-bit divide is pointless, but that is admittedly # expecting a fair amount of the compiler. # # IOW, we shouldn't write code that the compiler then has to notice is # unnecessarily complicated just to avoid extra work. We do have fairly # high expectations of compilers, but kernel code should be reasonable to # begin with. # # It turns out that there are also other issues with this code: the KUnit # assertion messages have incorrect types in the format strings, but # that's a widely spread issue caused by the KUnit infrastructure not # having enabled format string verification. We'll get that sorted out # separately. # # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: a64056bb5a32 ("drm/tests/drm_buddy: add alloc_contiguous test") # Link: https://lore.kernel.org/all/538327ff-8d34-41d5-a9ae-1a334744f5ae@roeck-us.net/ # Cc: Matthew Auld <matthew.auld@intel.com> # Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> # Cc: Christian König <christian.koenig@amd.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.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 fca7526b7d8910c6125cb1ebc3e78ccd5f50ec52 # 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/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/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/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: 0:00:54.371934
