Pull documentation fixes from Jonathan Corbet: "A handful of fixes in and around documentation. Some funky quotes in LICENSES/dual/CC-BY-4.0 were giving spdxcheck.py grief; that has been fixed on both ends. Also a couple of features updates and one docs build fix" * tag 'docs-5.14-2' of git://git.lwn.net/linux: docs/zh_CN: add a missing space character Documentation/features: Add THREAD_INFO_IN_TASK feature matrix Documentation/features: Update the ARCH_HAS_TICK_BROADCAST entry LICENSES/dual/CC-BY-4.0: Git rid of "smart quotes" scripts/spdxcheck.py: Strictly read license files in utf-8
