When the system reboots, the rng seed that QEMU passes should be
re-randomized, so that the new boot gets a new seed. This series wires
that up for FDT.
Then, since the record&replay subsystem makes use of reset as well, we
add a new reset cause for record&replay, so that we can avoid
re-randomizing in these cases.
Jason A. Donenfeld (8):
device-tree: add re-randomization helper function
arm: re-randomize rng-seed on reboot
riscv: re-randomize rng-seed on reboot
openrisc: re-randomize rng-seed on reboot
rx: re-randomize rng-seed on reboot
mips: re-randomize rng-seed on reboot
reset: allow registering handlers that aren't called by snapshot
loading
reset: do not re-randomize RNG seed on snapshot load
