    crypto: run initcalls for generic implementations earlier · c4741b23
    Eric Biggers authored
    Use subsys_initcall for registration of all templates and generic
    algorithm implementations, rather than module_init.  Then change
    cryptomgr to use arch_initcall, to place it before the subsys_initcalls.
    
    This is needed so that when both a generic and optimized implementation
    of an algorithm are built into the kernel (not loadable modules), the
    generic implementation is registered before the optimized one.
    Otherwise, the self-tests for the optimized implementation are unable to
    allocate the generic implementation for the new comparison fuzz tests.
    
    Note that on arm, a side effect of this change is that self-tests for
    generic implementations may run before the unaligned access handler has
    been installed.  So, unaligned accesses will crash the kernel.  This is
    arguably a good thing as it makes it easier to detect that type of bug.
