I just noticed that _PAGE_WRITETHRU is defined in the linuxppc_2_4 tree but not
in
the linuxppc_2_4_devel tree, which is the one I am using :-(. Has this
"function" been removed ,
never to return or is the devel tree in a flux now for mpc8xx?
If it has been removed, please reconsider adding it again. Now that burstable
flash devices are
common and there is a flash based FS(JFFS2) in the kernel, I think there will
be a need for
this functionality.
