Subject: [PATCH 0/4] x86/bus_lock: Set rate limit for bus lock
Date: Mon, 19 Apr 2021 21:49:54 +0000	[thread overview]
Message-ID: <20210419214958.4035512-1-fenghua.yu@intel.com> (raw)

Bus lock warn and fatal handling is in tip. This series sets system
wide bus lock rate limit to throttle malicious code.

This series is applied on top of tip master branch.

Change Log:
-Set system wide rate limit instead of per-user rate limit (Thomas).
-Thomas suggested to split the previous bus lock into warn and fatal
patch set and this rate limit patch set:
