kunit parses .config in the `build_reconfig()` of `run_tests()`.
Problematically, the current regex '^CONFIG_\w+=\S+$' does not allow for
spaces anywhere after the "=", even the option is a string.
So kunit will refuse to run if the existing .config has something like
CONFIG_CMDLINE="something and_something_else"
even if kunit.py will drop this entry when it regenerates the .config!
So relax the regex to allow entries that match `CONFIG_\w+=".*"` as a
minimal change. The question remains as to whether we should do any
validation of the string after the "=", however.

2.26.0.110.g2183baf09c-goog
This series introduces a new KVM selftest (mem_slot_test) that goal
is to verify memory slots can be added up to the maximum allowed. An
extra slot is attempted which should occur on error.
The patch 01 is needed so that the VM fd can be accessed from the
test code (for the ioctl call attempting to add an extra slot).
I ran the test successfully on x86_64, aarch64, and s390x. This
is why it is enabled to build on those arches.
- Changelog -
v3 -> v4:
- Discarded mem_reg_flags variable. Simply using 0 instead [drjones]
- Discarded kvm_region pointer. Instead passing a compound literal in
the ioctl [drjones]
- All variables are declared on the declaration block [drjones]
v2 -> v3:
- Keep alphabetical order of .gitignore and Makefile [drjones]
- Use memory region flags equals to zero [drjones]
- Changed mmap() assert from 'mem != NULL' to 'mem != MAP_FAILED' [drjones]
- kvm_region is declared along side other variables and malloc()'ed
later [drjones]
- Combined two asserts into a single 'ret == -1 && errno == EINVAL'
[drjones]
v1 -> v2:
- Rebased to queue
- vm_get_fd() returns int instead of unsigned int (patch 01) [drjones]
- Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones]
- Replaced DEBUG() with pr_info() [drjones]
- Calculate number of guest pages with vm_calc_num_guest_pages()
[drjones]
- Using memory region of 1 MB sized (matches mininum needed
for s390x)
- Removed the increment of guest_addr after the loop [drjones]
- Added assert for the errno when adding a slot beyond-the-limit [drjones]
- Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES,
so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones]
- Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite".

2.17.2
Avoid using /usr/bin/timeout unnecessarily if timeout is set to 0
(disabled) in the "settings" file for a specific test.
NOTE: without this change (and adding timeout=0 in the corresponding
settings file - tools/testing/selftests/seccomp/settings) the
seccomp_bpf selftest is always failing with a timeout event during the
syscall_restart step.

From: Tim Bird <tim.bird(a)sony.com>
It is useful for CI systems to be able to query the list
of targets provided by kselftest by default, so that they
can construct their own loop over the targets if desired.
