This is a one line patch split out from:
https://sourceware.org/ml/libc-alpha/2017-08/msg01310.html
It just changes the type of the argument passed to ifunc resolvers from
'unsigned int long' to 'uint64_t'. This should make no difference for
the existing LP64 ABI but will also work for the new ILP32 ABI. I
would like to check this in before submitting a patch to GCC that uses
IFUNCs in libatomic so that the types agree.
Tested on aarch64, OK to checkin?
