Module Name:    src

Log Message:
Ensure that the size of the stack is properly specified (2*USPACE) so it matches the allocation of stack pages done in pmap_bootstrap(). If this is not properly in sync, then the stack pointer may 
end up in the redzone right before the stack causing mmu faults. This issue has been observed on a T2000 (sun4v) system while probing the devices (pci/ebus/com) during bootstrap
