Subject: x86, pat: ioremap to follow same PAT restrictions as other PAT users
X-Git-Tag: v2.6.32-rc1~680^2~12
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=279e669b3fc0068cc3509e8e53036999e1e86588;p=pandora-kernel.git

x86, pat: ioremap to follow same PAT restrictions as other PAT users

ioremap has this hard-coded check for new type and requested type. That
check differs from other PAT users like /dev/mem mmap, remap_pfn_range
in only one condition where requested type is UC_MINUS and new type
is WC. Under that condition, ioremap fails. But other PAT interfaces succeed
with a WC mapping.

Change to make ioremap be in sync with other PAT APIs and use the same
macro as others. Also changes the error print to KERN_ERR instead of
pr_debug.
