[PATCH 35/40] bootlinux: Install pre-built kernels from packages

[Luis Chamberlain <mcgrof@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

Add the tasks needed to install a kernel on a test host from a
pre-built package (either .deb or .rpm). These are run when the
new WORKFLOW_LINUX_PACKAGED Kconfig option is selected.
