Subject[PATCH RFC 0/7] revert RNG seed mess
All attempts to fix up passing RNG seed via setup_data entry failed.
Let's just rip out all of it. We'll start over.


Warning: all I did was git revert the relevant patches and resolve the
(trivial) conflicts. Not even compiled - it's almost midnight here.

Jason this is the kind of approach I'd like to see, not yet another
pointer math rich patch I need to spend time reviewing. Just get us back
to where we started. We can redo "x86: use typedef for SetupData struct"
later if we want, it's benign.

Could you do something like this pls?
Or test and ack if this patchset happens to work by luck.

Michael S. Tsirkin (7):
Revert "x86: don't let decompressed kernel image clobber setup_data"
Revert "x86: do not re-randomize RNG seed on snapshot load"
Revert "x86: re-initialize RNG seed when selecting kernel"
Revert "x86: reinitialize RNG seed on system reboot"
Revert "x86: use typedef for SetupData struct"
Revert "x86: return modified setup_data only if read as memory, not as
file"
Revert "hw/i386: pass RNG seed via setup_data entry"
