DE5_NET OpenCL support on Ubuntu 16.10

With the help of Michal Hocko, and Lorenzo Stoakes I found the solution!

Thank you so much guys!!

In some newer kernels (I am using 4.8) you can simply use get_user_pages_remote instead get_user_pages.

For some kernels, the parameter list is exactly the same!!

Be carefull, than recent kernels have a slightly different parameter list, but that I guess that can be easily adapted.

To be able to support both (4.4) and (4.8) kernels I modifyed the code as follows...

# if LINUX_VERSION_CODE < KERNEL_VERSION(4,6,0)

ret = get_user_pages(target_task, target_task->mm,

start_page + got * PAGE_SIZE,

num_pages - got,

1, 1,

p + got, vma);

# else

ret = get_user_pages_remote(target_task, target_task->mm,

start_page + got * PAGE_SIZE,

num_pages - got,

1,1, p+got,

vma);

# endif

Now ">aocl diagnose acl0" seems to be working smoothly on 4.8 !!
