Subject: get_unmapped_area handles MAP_FIXED on parisc
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
Handle MAP_FIXED in parisc arch_get_unmapped_area(), just return the address.
We might want to also check for possible cache aliasing issues now that we get
called in that case (like ARM or MIPS), leave a comment for the maintainers to
pick up.
