This patch implements the kthread helper functions kthread_start

It is still assumed that eventually we will get around to requesting

Hi Alan,
I believe that dma_alloc_coherent will mark the kernel buffer as uncached at

But that is not my intention. I have mapped some user space memory to the
kernel buffer and I wish to ensure that the contents of both are coherent and
correctly ordered.

Heap management? What syscalls?
Trying to answer this question, I straced the mysql threads that

Currently because vmlinux does not reflect that the kernel is relocatable

Now that the vmlinux is marked as relocatable there is no reason to
