It does this by calling that # function early in boot and checking if it returns -ENOSYS. # # That is fine but unnecessary on powerpc, as we always have support for # futex_atomic_cmpxchg_inatomic() if the kernel is built with FUTEX # support. It also means the first page fault we take at boot is on a # deliberate NULL pointer in kernel space, which can be confusing if # you're debugging the page fault code. # # We can avoid the runtime check by selecting HAVE_FUTEX_CMPXCHG, so # let's do that. # # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # <
