Subject: x86: avoid duplicate running of pud_offset and pmd_offset in one_md_table_init()
X-Git-Tag: v2.6.29-rc1~536^2~54

x86: avoid duplicate running of pud_offset and pmd_offset in one_md_table_init()

Impact: simplify implementation, cleanup

If !(pgd_val(*pgd) & _PAGE_PRESENT) in PAE mode, we need not get value of
pmd_table again.
