[PATCH 2.6.22] [3/5] x86_64: Change PMDS invocation to single macro

From: Andi Kleen
Date: Wed Aug 15 2007 - 06:40:39 EST



Very old binutils (2.12.90...) seem to have trouble with newlines
in assembler macro invocation. They put them into the resulting
argument expansion. In this case this lead to a parse error because
a .rept expression ended up spread over multiple lines. Change the PMDS()
invocation to a single line.
