[Impact]

This patchset previously requested by Google has been found to cause
crashes without a dependency commit:
e4891e4687c8 ("idpf: split &idpf_queue into 4 strictly-typed queue structures")
This requires a rework of the patchset, so we need to pull it from the
current cycle until further notice.

[Fix]

The patchset is reverted for all affected kernels. Another email was
sent for the Jammy/Noble version of the patchset.

[Where problems could occur]

Reverting this fix reintroduces the problems originally intended to be
solved by the patchset, but prevents new major crashes and should
generally be a net benefit to stability of the kernel. These kernels
will go through normal rounds of testing for the cycle.
