Sparse emits a large number of warnings for the linux kernel source tree of the form: ./arch/x86/include/asm/uaccess.h:735:18: \ warning: incorrect type in argument 1 (different modifiers) ./arch/x86/include/asm/uaccess.h:735:18: expected void *<noident> ./arch/x86/include/asm/uaccess.h:735:18: got void const *from Fix by making the first parameter to __builtin_object_size() type "const void *" instead of "void *", which is consistent with GCC behavior (the prototype for this builtin in GCC documentation is evidently incorrect).
