Subject: [PATCH v3 0/2] Getting rid of CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE

Hi Peter / Tony.

Sorry for the rebase snafu with v2.

So kbuild service reported build failure of ia64 with v1 of the patch.
I've added an untested atomic64_dec_if_positive() to ia64, shamelessly
copied from s390 with some adjustments 64-bit long etc. Could you please
double check.

It builds fine with ia64 cross compiler.

Thx,
-Vineet

  ia64: implement atomic64_dec_if_positive
  atomic64: No need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
