@ -119,6 +119,16 @@ To avoid this, you can make the vDSO different for different
kernel versions by including an arbitrary string of "salt" in it.
This is specified by the Kconfig symbol ``CONFIG_BUILD_SALT``.
Git
---
Uncommitted changes or different commit ids in git can also lead
to different compilation results. For example, after executing
``git reset HEAD^``, even if the code is the same, the
``include/config/kernel.release`` generated during compilation
will be different, which will eventually lead to binary differences.
See ``scripts/setlocalversion`` for details.
