Re: About the MmMapIoSpace function 's source code

Tech-Archive recommends: Fix windows errors by optimizing your registry

It is because PAGE_PHYSICAL is also set. As documented when using that flag
you must shift by 8. This is to allow for processors, like the MIPS, that
have a 36 bit physical address space
