Copying Module.symvers is the oldest supported method for building external kernel modules that depend on another external kernel module. Since support for that method will be removed from Linux kernel v5.5, use KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in upstream kernel v2.6.26 so this patch drops support for kernels before v2.6.26. git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@8686 d57e44dd-8a1f-0410-8b47-8ef2f437770f
