   4 Subject: [PATCH] wireguard: selftests: use normal kernel stack size on ppc64
   5
   6 commit a0fd7cc87a018df1a17f9d3f0bd994c1f22c6b34 upstream.
   7
   8 While at some point it might have made sense to be running these tests
   9 on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on
  10 64-bit powerpc in a long time, and more interesting things that we test
  11 don't really work when we deviate from the default (16k). So, we stop
  12 pushing our luck in this commit, and return to the default instead of
  13 the minimum.
