-# Install kernel (uapi) headers.

-# The dependency file serves two purposes:
-#  - It is a stamp indicating when the headers were last installed.
-#  - It contains a rule to regenerate itself when any kernel header
-#    files change.  This rule is identical to the rule emitted by
-#    GCC using the M/MM flags.
-#
-# Note that the location of installed kernel headers changed when the
-# kernel uapi system was introduced in 3.7.  Unfortunately, it is not
-# sufficient to test whether the uapi directories exist because some
-# kernels backport patches that contain uapi headers.  So we look for
-# the string "version_h" in the kernel makefile which was introduced
-# as a part of the uapi system (commit d183e6f570f3).
