The first four patches are improvements to page_flags_test().
The fifth is the patch I originally sent out which exposed some of
the weaknesses in page_flags_test().

v2:
 - use scnprintf (Rasmus)
 - remove page_flags variable (Kirill)

Matthew Wilcox (Oracle) (5):
  test_printf: Make pft array const
  test_printf: Remove separate page_flags variable
  test_printf: Remove custom appending of '|'
  test_printf: Append strings more efficiently
  vsprintf: Make %pGp print the hex value
