[PATCH v6 00/15] xen: Centralise byteswap infrastructure

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

The diffstat speaks for itself.

Compared to v6, one patch (TMEM) committed, one new patch (drivers/smmu-v3) to
fix a MISRA regression, and the __{BIG,LITTLE}_ENDIAN_BITFIELD logic is
retained.  See individual patches for details.
