Description: Linux kernel image for version 4.4.0 on 64 bit x86 SMP
This package contains the Linux kernel image for version 4.4.0 on
64 bit x86 SMP.
.
Also includes the corresponding System.map file, the modules built by the
packager, and scripts that try to ensure that the system is not left in an
unbootable state after an update.
.
Supports Generic processors.
.
Geared toward desktop and server systems.
