Okay, so to clean this up:
Commit:
fe57d86f7c3f ("powerpc/vdso: Don't use r30 to avoid breaking Go lang")
landed in impish / 21.10 starting with kernel:
Ubuntu-5.13.0-15
and we rae currently at level:
linux-generic | 5.13.0.16
hence it's already in impish's release pocket
and I can close this as Fix Released.
According to Krzysztof's comment the concerns about older versions are
causeless, since
Kernels older than v5.11 do not have commit switching vDSO to generic
implementation (which can touch r30), and should therefore not be affected.
