To support kmap_atomic_prot(), all architectures need to support
protections passed to their kmap_atomic_high() function. Pass
protections into kmap_atomic_high() and change the name to
kmap_atomic_high_prot() to match.
Then define kmap_atomic_prot() as a core function which cal

The kmap code for all the architectures is almost 100% identical.

During this kmap() conversion series we must maintain bisect-ability.
To do this, kmap_atomic_prot() in x86, powerpc, and microblaze need to
remain functional.

architectures so we can rework their kmap_atomic() ca

All architectures do exactly the same thing for kunmap(); remove all the
duplicate definitions and lift the call to the core.
This also has the benefit of changing kmap_unmap() on a number of

Every arch has the same code to ensure atomic operations and a check for
