Reduce stack usage for recursive traverse_visitbp()
...
Due to limited stack space recursive functions are frowned upon in
the Linux kernel. However, they often are the most elegant solution
to a problem. The following code preserves the recursive function
traverse_visitbp() but moves the local variables AND function
arguments to the heap to minimize the stack frame size. Enough
space is initially allocated on the stack for 20 levels of recursion.
This change does ugly-up-the-code but it reduces the worst case
usage from roughly 4160 bytes to 960 bytes on x86_64 archs.

Linux bcopy() requires word aligned memory, use memcpy()
...
Much to my surprise bcopy() under Linux appears to copy the data in
word sized chunks. It does the right thing but if you buffer is not
a multiple of the word size you will be reading past the end of your
buffer. Or at least that is what valgrind is reporting. We should
be using mempcy() anyway on Linux so replace bcopy() with memcpy()
to resolve the issue.

The following are 3 cases where move than 2 pages are allocated

to a slab.

Never sleep under taskq_dispatch()

There are cases where under Linux it is not safe to sleep in

allow a sleep here. The impact of this should be minimal.

I missed a instanse of removing the & operator when reducing the

update the topic branch to correct this mistake.
