Subject: [PATCH 5/7] sh: pte_mkhuge() compile fix for !CONFIG_HUGETLB_PAGE.
Date: Thu, 3 Nov 2005 00:31:40 +0200 [thread overview]
Message-ID: <20051102223140.GE27200@linux-sh.org> (raw)
Presently it is bogus to call pte_mkhuge() outside of the
CONFIG_HUGETLB_PAGE context, as the only processors that support
_PAGE_SZHUGE do so in the hugetlbpage context only (and this is the only
time that _PAGE_SZHUGE is even defined). SH-2 and SH-3 do not support
huge pages at all, and so it is not possible to enable this.
