The patchset has been pushed into printk/linux.git, branch
for-5.13-vsprintf-pgp. It should appear in linux-next again.

The first two patches are the same as in v5 that has already been
pushed earlier. I probably should have replaced only the last patch
but I rebased everything. It was too easy with the b4 tool. And
it is Friday late afternoon here.
