I know some ppc-mmu provide the capability to perform the endian swap
during page access. I wasn't aware that there is a kernel wide interface

Yuck.

There are some peripheral(e.g dwc otg) whose registers can be configured to
work in either little or big endian mode. Therefor macros like out_be32,
in_be32, out_le32 and in_le32 have been added to support such peripherals.
