bootup: move 'usermodehelper_enable()' a little earlier
Commit d5767c53535a ("bootup: move 'usermodehelper_enable()' to the end
of do_basic_setup()") moved 'usermodehelper_enable()' to end of
do_basic_setup() to after the initcalls. But then I get failed to let
uvesafb work on my computer, and lose the splash boot.
So maybe we could start usermodehelper_enable a little early to make
some task work that need eary init with the help of user mode.
[ I would *really* prefer that initcalls not call into user space - even
the real 'init' hasn't been execve'd yet, after all! But for uvesafb
it really does look like we don't have much choice.
I considered doing this when we mount the root filesystem, but
depending on config options that is in multiple places. We could do
the usermode helper enable as a rootfs_initcall()..
So I'm just using wang yanqing's trivial patch. It's not wonderful,
but it's simple and should work. We should revisit this some day,
though. - Linus ]
