init: move stack canary initialization after setup_arch
Patch series "Command line randomness", v3.
A series to add the kernel command line as a source of randomness.
This patch (of 2):
Stack canary intialization involves getting a random number. Getting this
random number may involve accessing caches or other architectural specific
features which are not available until after the architecture is setup.
Move the stack canary initialization later to accommodate this.
