[PATCH 0/5] Add more tests for user context functions

[H.J. Lu]

When the shadow stack (SHSTK) is enabled, makecontext needs to allocate
a new shadow stack to go with the new stack allocated by the caller.
setcontext and swapcontext must properly handle the corresponding shadow
stack when the stack is switched.  Add more tests for user context
functions to provide more coverage for the shadow stack support.

OK for master branch?

H.J. Lu (5):
  Add a test for swapcontext with a wrapper
  Add a test for multiple makecontext calls
  Add another test for setcontext
  Add a test for multiple setcontext calls
  Add tests for setcontext on the context from makecontext
