Subject: Make check_signature depend on CONFIG_HAS_IOMEM
X-Git-Tag: v2.6.23-rc1~772
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a54890d7a6f37a4658294cbce650af4d1fabb8c9;p=linux-2.6

Make check_signature depend on CONFIG_HAS_IOMEM

This should avoid build problems on architectures without a "readb()",
that got bitten by check_signature() being uninlined.
