Subject: Call init_workqueues before pre smp initcalls.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a802dd0eb5fc97a50cf1abb1f788a8f6cc5db635;p=linux-beck.git

Call init_workqueues before pre smp initcalls.

This allows to create workqueues from within the context of
a pre smp initcall (aka early_initcall).
