The current check for 64-bit architecture is double-bugged. First of all, %BITS_PER_LONG is not available in the userspace, the underscored version from <asm/bitsperlong.h> must be used. The following check:
#if BITS_PER_LONG == 0 #error #endif
triggers the error in this source file -- the macro is undefined and thus is implicitly evaluated to 0. Next, %BITS_PER_LONG means "bits", not "bytes". In the Linux kernel, it can be 32 or 64, never 8. Given that the tests guarded by that check are meant to be run on a 64-bit system, the correct value would be 64.
Prefix the macro name and fix the value it's compared to.
