debian-testing 5.8 kernel fix

Hi,

down_read (&mm->mmap_sem);
     has evolved to
mmap_read_lock (mm);

Same things for up_{read,write} and *_trylock()

I fixed the source code and I am providing a patch.


Thanks you :-))

P.S.: I also included generated/utsrelease.h instead of linux/vermagic.h to
avoid an new pre-processor #error statement
