commit 71f7c79c7af817477e553103c9eb03926e12ada4
Author: Hector Martin <[email protected]>
Date:   Mon Dec 20 20:00:57 2021 +0900

    brcmfmac: chip: Only disable D11 cores; handle an arbitrary number
    
    At least on BCM4387, the D11 cores are held in reset on cold startup and
    firmware expects to release reset itself. Just assert reset here and let
    firmware deassert it. Premature deassertion causes weird
    nondeterministic AXI errors on firmware startup.

commit e89c8eecc756600ec3dbf1fed73620592eae55af

    brcmfmac: cfg80211: Pass PMK in binary
    
    Apparently the hex passphrase mechanism does not work on newer firmware.
    (Does this need a feature flag?)

 * m1cat: a proof of concept for the M1RACLES vulnerability in the Apple M1.
 * 
 * This program implements a covert channel that can be used to transmit data
 * between two processes when run on the Apple Silicon "M1" CPUs.
 *
 * The channel is slightly lossy due to (presumably) the scheduler sometimes
 * scheduling us on the wrong CPU cluster, so this PoC sends every byte twice
 * together with some metadata/framing bits, which is usually good enough.
 * A better approach would be to use proper FEC or something like that.
