dax: does not work correctly with virtual aliasing caches
The DAX code accesses the underlying storage through the kernel's linear
mapping, which may not be cache-coherent with user mappings on ARM, MIPS
or SPARC. Temporarily disable the DAX code until this problem is
resolved.
The original XIP code also had this problem, but it was never noticed.
