_PAGE_WRITETHRU is a target specific flag. Prefer generic functions.

Hi Geert,

All patches that have been applied to this driver since 2005 are API refactoring
patches. I haven't found any patches in the history of this driver that seem to
have been submitted by a user of this driver. Do you perhaps know whether anyone
is using this driver?

Thanks,

Bart.
