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_se7750_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- se7750_defconfig # < make -s -j 160 ARCH=sh O=/kisskb/build/linus_se7750_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_se7750_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_se7750_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/pgtable.c:10:6: warning: no previous prototype for 'pgd_ctor' [-Wmissing-prototypes] 10 \| void pgd_ctor(void x) \| ^~~~~~~~ /kisskb/src/arch/sh/mm/pgtable.c:32:8: warning: no previous prototype for 'pgd_alloc' [-Wmissing-prototypes] 32 \| pgd_t pgd_alloc(struct mm_struct mm) \| ^~~~~~~~~ /kisskb/src/arch/sh/mm/pgtable.c:37:6: warning: no previous prototype for 'pgd_free' [-Wmissing-prototypes] 37 \| void pgd_free(struct mm_struct mm, pgd_t pgd) \| ^~~~~~~~ /kisskb/src/arch/sh/mm/flush-sh4.c:106:13: warning: no previous prototype for 'sh4__flush_region_init' [-Wmissing-prototypes] 106 \| void __init sh4__flush_region_init(void) \| ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/tlbex_32.c:22:1: warning: no previous prototype for 'handle_tlbmiss' [-Wmissing-prototypes] 22 \| handle_tlbmiss(struct pt_regs regs, unsigned long error_code, \| ^~~~~~~~~~~~~~ /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/mm/cache-sh4.c:384:13: warning: no previous prototype for 'sh4_cache_init' [-Wmissing-prototypes] 384 \| void __init sh4_cache_init(void) \| ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh4/fpu.c:389:6: warning: no previous prototype for 'float_raise' [-Wmissing-prototypes] 389 \| void float_raise(unsigned int flags) \| ^~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh4/fpu.c:394:5: warning: no previous prototype for 'float_rounding_mode' [-Wmissing-prototypes] 394 \| int float_rounding_mode(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, \| ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/boot/compressed/cache.c:2:5: warning: no previous prototype for 'cache_control' [-Wmissing-prototypes] 2 \| int cache_control(unsigned int command) \| ^~~~~~~~~~~~~ /kisskb/src/arch/sh/boot/compressed/misc.c:115:6: warning: no previous prototype for 'ftrace_stub' [-Wmissing-prototypes] 115 \| void ftrace_stub(void) \| ^~~~~~~~~~~ /kisskb/src/arch/sh/boot/compressed/misc.c:118:6: warning: no previous prototype for 'arch_ftrace_ops_list_func' [-Wmissing-prototypes] 118 \| void arch_ftrace_ops_list_func(void) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/boot/compressed/misc.c:128:6: warning: no previous prototype for 'decompress_kernel' [-Wmissing-prototypes] 128 \| void decompress_kernel(void) \| ^~~~~~~~~~~~~~~~~ Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_se7750_defconfig_sh4-gcc13 # Build took: 0:01:04.418242
