From: Andi Kleen <redacted> Bugfix, independent from the rest of the series. The THP code didn't pass the correct interleaving shift to the memory policy code. Fix this here by adjusting for the order. Cc: aarcange@redhat.com Signed-off-by: Andi Kleen <redacted> --- mm/mempolicy.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
