PA-RISC Arch 1.1 book says:
On page 3-14:

	Exact form of these tables is s/w convention. 

Q.	If the format is software convention, does that mean
	the fields within TLB slots are not defined by Hardware ?
	Though  the book does seem to indicate what fields are needed
	in a pdir entry. Without knowing exact positions of various
	fields how would TLB entries be updated from pdir entries in
	memory ?

	Other interesting point to note is that PA-RISC does not
	define how many entries in the table etc. Very much unlike
	x86.
