[PATCH V3 16/30] powerpc/mm: Rename hash specific page table bits (_PAGE* -> H_PAGE*)
Aneesh Kumar K.V

Fri Feb 19 03:50:40 AEDT 2016
This patch renames _PAGE* -> H_PAGE*. This enables us to support
different page table format in the same kernel. Between radix and
hash we will have different bit position to indicate different pte
states like dirty, present etc. Inorder to enable single kernel to
support both radix and hash page table format, a pte accessor need to
check for different bits depending on which config we are using.
For ex: a pte dirty check would end up
pte_dirty(pte_t pte)
{
if (radix_enabled())
pte & _RPAGE_DIRTY;
else
pte & H_PAGE_DIRTY;
}
Some of the defines used by core kernel like PMD_SHIFT are now converted
to variables so that we can avoid conditional there. ie, we do
