Four stable kernels to fix problematic commit

Greg-Kroah Hartman has released the 6.19.2, 6.18.12, 6.12.73, and 6.6.126 stable kernels. These kernels
each contain a single change; Kroah-Hartman has reverted one
problematic commit that prevents some systems from booting. “If the
last stable release worked just fine, no need to upgrade.“
