https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-4.6.y2015-10-02T07:43:21Zx86/headers/uapi: Fix __BITS_PER_LONG value for x32 builds2015-10-02T07:43:21ZBen Hutchings2015-10-01T00:40:43Zurn:sha1:f4b4aae1828855db761bf998ce37d3062b1d6446
On x32, gcc predefines __x86_64__ but long is only 32-bit. Use
__ILP32__ to distinguish x32.
Fixes this compiler error in perf:
tools/include/asm-generic/bitops/__ffs.h: In function '__ffs':
tools/include/asm-generic/bitops/__ffs.h:19:8: error: right shift count >= width of type [-Werror=shift-count-overflow]
word >>= 32;
^
This isn't sufficient to build perf for x32, though.
