Example:
drivers/acpi/processor_core.i:6109:26: error: Expected ) at end of cast operator
drivers/acpi/processor_core.i:6109:26: error: got __int128
Passing a large list of files causes the error count to exceed 100, whereupon
sparse exits.
The offending source is in include/linux/math64.h
#if defined(CONFIG_ARCH_SUPPORTS_INT128) && defined(__SIZEOF_INT128__)
#ifndef mul_u64_u32_shr
static inline u64 mul_u64_u32_shr(u64 a, u32 mul, unsigned int shift)
{
return (u64)(((unsigned __int128)a * mul) >> shift);
}
#endif /* mul_u64_u32_shr */
Of course, disabling 64-bit kernel in .config removes the problem, but this is
an unacceptable solution.
I can't see clearly why sparse should flag this as an error.
