Mark Johnston f13fa9df05 Use a single VM object for kernel stacks. 
Previously we allocated a separate VM object for each kernel stack.
However, fully constructed kernel stacks are cached by UMA, so there is
no harm in using a single global object for all stacks.  This reduces
memory consumption and makes it easier to define a memory allocation
policy for kernel stack pages, with the aim of reducing physical memory
fragmentation.

Add a global kstack_object, and use the stack KVA address to index into
the object like we do with kernel_object.
