The build problem when HOTPLUG_CPU is disabled is still present. The
kernel needs to build with this option disabled.
Enabling HOTPLUG_CPU in defconfig doesn't force everyone to enable that
configuration option; not everyone uses tegra_defconfig, people don't
always update to the latest defconfig, people should be free to disable
functionality they don't need and still get a buildable & working
kernel, etc.
Besides, even if defconfig were a legitimate solution to this problem,
this series still wouldn't work with "git bisect", since the defconfig
patch comes after the patch that causes the build failure.

The reboot problem is indeed solved.
P.S. It'd be nice to include a summary of what changed in each affected
patch, as well as in the cover letter.
