Christophe Leroy 3ff38e1874 powerpc/book3s64: fix dump_linuxpagetables "present" flag 
Since commit bd0dbb73e0 ("powerpc/mm/books3s: Add new pte bit to
mark pte temporarily invalid."), _PAGE_PRESENT doesn't mean exactly
that a page is present. A page is also considered preset when
_PAGE_INVALID is set.

This patch changes the meaning of "present" and adds a status "valid"
associated to the _PAGE_PRESENT flag.

Fixes: bd0dbb73e0 ("powerpc/mm/books3s: Add new pte bit to mark pte temporarily invalid.")

Christophe Leroy 97026b5a5a powerpc/mm: Split dump_pagelinuxtables flag_array table 
To reduce the complexity of flag_array, and allow the removal of
default 0 value of non existing flags, lets have one flag_array
table for each platform family with only the really existing flags.
