Hey Linus,

Please pull the following fixes for 5.17-rc3. There are a few other patches in
my tree that fix an age old crypto ~vuln, but I think I'll give those a few
more days to stew on the list before submitting. So expect to hear from me
about that next week. For this week, we have:

1) A fix to make more frequent use of hwgenerator randomness, from Dominik.

2) More cleanups to the boot initialization sequence, from Dominik.

3) A fix for an old shortcoming with the ZAP ioctl, from me.

4) A workaround for a still unfixed Clang CFI/FullLTO compiler bug, from me.
   On one hand, it's a bummer to commit workarounds for experimental compiler
   features that have bugs. But on the other, I think this actually improves
   the code somewhat, independent of the bug. So a win-win.

Thanks,
Jason
