Ninja: Unexpected kernel parameters found:
  maxcpus=2 

Clapper: Unexpected kernel parameters found:
  maxcpus=3 

First, I'm surprised anyone is specifying maxcpus...but I'm assuming there is some good reason for doing so since several public overlays are doing this:
grundler@firesword ~/trunk/src/overlays $ fgrep -R maxcpus
overlay-heli/scripts/build_kernel_image.sh:  echo "maxcpus=3" >> "$1"
overlay-candy/scripts/build_kernel_image.sh:  echo "maxcpus=3" >> "$1"

ninja added the maxcpus with this change as a workaround:

I'm going to guess most of the above are running chromeos-4.4 kernel and suffering some common issue...  which suggests ensure_secure_kernelparams.sh needs to be modified to accept this parameter. Any objections?

Agreed, this should already be fixed by https://chrome-internal-review.googlesource.com/#/c/360789/

Perhaps this just needs to be merged into 59?

c#9: yes, merging to M59 should do the trick. Bernie, did you want to do that yourself?

looks like the merge happened and this is fixed. https://cros-goldeneye.corp.google.com/chromeos/console/listBuild?boards=banjo%2Ccandy%2Ccandy-freon%2Cclapper%2Cclapper-freon%2Ccranky%2Cenguarde%2Cenguarde-freon%2Cexpresso%2Cexpresso-freon%2Cglimmer%2Cglimmer-freon%2Cgnawty%2Cgnawty-freon%2Cheli%2Ckip%2Ckip-freon%2Cninja%2Corco%2Cparry%2Cquawks%2Cquawks-freon%2Crambi%2Crambi-freon%2Csquawks%2Csquawks-freon%2Csumo%2Cswanky%2Cswanky-freon%2Cwinky%2Cwinky-freon&milestone=59&chromeOsVersion=&chromeVersion=&startTimeFrom=&startTimeTo=#%2F
