[PATCH] powerpc: Better pmd_bad() and pud_bad() checks
At present, the powerpc pmd_bad() and pud_bad() macros return false
unless the given pmd or pud is zero. This patch makes these tests
more thorough, checking if the given pmd or pud looks like a plausible
pte page or pmd page pointer respectively. This can result in helpful
error messages when messing with the pagetable code.
