Subject: comedi/drivers.c uses PAGE_KERNEL_NOCACHE

I noticed the following build failure in comedi/drivers.c on ARM:

| drivers/staging/comedi/drivers.c:497: error: 'PAGE_KERNEL_NOCACHE' undeclared (first use in this function)

Apparently Geert Uytterhoeven pointed out this problem back in January:
"which requires PAGE_KERNEL_NOCACHE, which is defined on 4 out of 22
architectures only (x86, frv, m32r, mn10300)." - http://lkml.org/lkml/2009/1/12/45

Is anything being done about this problem?

Oops, sorry, no, I missed that one.
