In a previous series testing was added to verify that when a #PF occured in L2 the exception was routed to the correct place. In this series other exceptions are tested (ie: #GP, #UD, #DE, #DB, #BP, #AC). The first two commits in this series are bug fixes that were discovered while making these changes. The last two implement the tests. v1 -> v2: - Add guest_stack_top and guest_syscall_stack_top for aligning L2's stacks. - Refactor test to make it more extensible (ie: Added vmx_exception_tests array and framework around it). - Split test into 2 commits: 1. Test infrustructure. 2. Test cases.
