Subject: x86/mm/pat: Add set_memory_wt() for Write-Through type
X-Git-Tag: omap-for-v4.2/fixes-rc1^2~170^2^3~3
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=623dffb2a2e059e1ace45b59b3ff21c66c419614;p=pandora-kernel.git

x86/mm/pat: Add set_memory_wt() for Write-Through type

Now that reserve_ram_pages_type() accepts the WT type, add
set_memory_wt(), set_memory_array_wt() and set_pages_array_wt()
in order to be able to set memory to Write-Through page cache
mode.

Also, extend ioremap_change_attr() to accept the WT type.
