[PATCH] x86_64: align per-cpu section to configured cache bytes

Browse source

Align the start of the per-cpu section to the configured number of bytes in a
cache line.  This stops a BUG_ON() from triggering in load_module() when
DEFINE_PER_CPU() is used in a module and the section isn't cacheline-aligned.
Rusty also found this and sent a patch in a while ago
(http://lkml.org/lkml/2004/10/19/17), I don't know what came of that.
