Cover letter [patch 0/5] access_process_vm device memory access
In order to be able to debug things like the X server and programs using the PPC Cell SPUs, the debugger needs to be able to access device memory through ptrace and /proc/pid/mem.
Changelog:
- use CONFIG_HAVE_IOREMAP_PROT
- do not use generic_access_phys as a fallback but define it in the ->vm_ops->access for appropriate VMAs
- other code cleanups suggested by Andrew Morton and Sam Ravnborg
