[PATCH 0/2] exec: Add KUnit test for bprm_stack_limits()

[Kees Cook]

Hi,

This adds a first KUnit test to the core exec code. With the ability to
manipulate userspace memory from KUnit coming[1], I wanted to at least
get the KUnit framework in place in exec.c. Most of the coming tests
will likely be to binfmt_elf.c, but still, this serves as a reasonable
first step.
