John W. Linville 209ccf6f16 kernel/range: Uplevel the cxl subsystem's range_contains() helper 
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2168268

In support of the CXL subsystem's use of 'struct range' to track decode
address ranges, add a common range_contains() implementation with
identical semantics as resource_contains();

The existing 'range_contains()' in lib/stackinit_kunit.c is namespaced
with a 'stackinit_' prefix.

Nico Pache 3f59061e96 lib: stackinit: Convert to KUnit 
commit 02788ebcf521fe78c24eb221fd1ed7f86792c330
Author: Kees Cook <keescook@chromium.org>
Date:   Wed Feb 16 16:03:41 2022 -0800

    lib: stackinit: Convert to KUnit

    Convert stackinit unit tests to KUnit, for better integration
    into the kernel self test framework. Includes a rename of
    test_stackinit.c to stackinit_kunit.c, and CONFIG_TEST_STACKINIT to
    CONFIG_STACKINIT_KUNIT_TEST.

    Adjust expected test results based on which stack initialization method
    was chosen:

     $ CMD="./tools/testing/kunit/kunit.py run stackinit --raw_output \
            --arch=x86_64 --kconfig_add"

     $ $CMD | grep stackinit:
     # stackinit: pass:36 fail:0 skip:29 total:65

     $ $CMD CONFIG_GCC_PLUGIN_STRUCTLEAK_USER=y | grep stackinit:
     # stackinit: pass:37 fail:0 skip:28 total:65

     $ $CMD CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF=y | grep stackinit:
     # stackinit: pass:55 fail:0 skip:10 total:65

     $ $CMD CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL=y | grep stackinit:
     # stackinit: pass:62 fail:0 skip:3 total:65

     $ $CMD CONFIG_INIT_STACK_ALL_PATTERN=y --make_option LLVM=1 | grep stackinit:
     # stackinit: pass:60 fail:0 skip:5 total:65

     $ $CMD CONFIG_INIT_STACK_ALL_ZERO=y --make_option LLVM=1 | grep stackinit:
     # stackinit: pass:60 fail:0 skip:5 total:65

    Temporarily remove the userspace-build mode, which will be restored in a
    later patch.

    Expand the size of the pre-case switch variable so it doesn't get
    accidentally cleared.
