commit d6ed083f5cc621e15c15b56c3b585fd524dbcb0f upstream.
The bounds check used the uninitialized variable vaddr, it should use
the given parameter kaddr instead. When using the uninitialized value
the compiler assumed it to be 0 and optimized this function to just
return 0 in all cases.
This should make the function check the range of the given address and
only do the page map check in case it is in the expected range of
virtual addresses.
