Subject: [PATCH] Use send_sig() instead of kill_proc() in emulated kthread
 support.

This allows to compile driver on latest 2.6.27+ kernels,
but is incorrect anyway. The local code for kernel thread
support is not more needed for recent 2.6 kernels and code
should be modified to emulate same interface for older ones.
