[PATCH 5.2 109/131] parisc: Strip debug info from kernel before creating compressed vmlinuz

[Greg Kroah-Hartman]

From: Helge Deller <deller@xxxxxx>

commit e50beea8e7738377b4fa664078547be338038ff9 upstream.

Same as on x86-64, strip the .comment, .note and debug sections from the
Linux kernel before creating the compressed image for the boot loader.
