[patch-mm 20/23] x86_64: restore restore nohpet cmdline

[Thomas Gleixner]

From: Chris Wright <chrisw@xxxxxxxxxxxx>

Lost when merged with i386.  Happy to drop, but I suspect Andi would
rather not break existing users (I noticed because it was part of my
testing).  If dropped, Documentation needs updating.
