Subject: [PATCH 0/7] Expect immutable pointer in virt_to_phys/isa_virt_to_bus
 prototypes

This series is aimed to address compilation warnings when a constant pointer
is passed to virt_to_phys and isa_virt_to_bus functions:

  warning: passing argument 1 of ‘virt_to_phys’ discards ‘const’ qualifier from pointer target type
  warning: passing argument 1 of ‘isa_virt_to_bus’ discards ‘const’ qualifier from pointer target type

The change(s) is the same for all architectures, but it's split into a series on
per-arch basis to simplify applying and testing on the maintainers side.

The following series implements...
