-Subject: [PATCH] fix regression disabling use of pause instruction for x86
- a_spin
-
-commits e24984efd5c6ac5ea8e6cb6cd914fa8435d458bc and
-16b55298dc4b6a54d287d7494e04542667ef8861 inadvertently disabled the
-a_spin implementations for i386, x86_64, and x32 by defining a macro
-named a_pause instead of a_spin. this should not have caused any
-functional regression, but it inhibited cpu relaxation while spinning
-for locks.
-
-bug reported by George Kulakowski.
