| |
2.6.11 gave __GFP_ZERO's prep_zero_page a bogus "highmem may have to wait" assertion. Presumably added under the misconception that clear_highpage uses nonatomic kmap; but then and now it uses kmap_atomic, so no problem.
Signed-off-by: Hugh Dickins <hugh@veritas.com> --- No need for this one in -stable: nobody hit it but me in making other changes.
