[RESEND PATCH v2 1/2] x86/mm/pat, drivers/infiniband/ipath: replace WARN() with pr_warn()

["Luis R. Rodriguez" <mcgrof@do-not-panic.com>]

From: "Luis R. Rodriguez" <mcgrof@suse.com>

WARN() may confuse users, fix that. ipath_init_one() is part the
device's probe so this would only be triggered if a corresponding
device was found.
