parisc: use constants instead of numbers in assembly
A few small fixups: * _PAGE_SIZE_ENCODING_DEFAULT is wrong here, as one might assume that it's possible to define the page size that way. This is wrong. Use 0 instead. * use constants instead of hardcoded numerical values in depi and extru while building the PFN out of the pte entry * use SHRREG instead of extru (iitlba expects the PFN at bits {7..26}) Still wondering why we can use the same register (pte) as extru source and target register, but it seems to work on PA1.1 and PA2.0...
