Subject: s390/nmi: initialize control register 0 earlier
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24d05ff863e78544e8538a792e3234291cdd5650;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/nmi: initialize control register 0 earlier

Change machine_check_init() to an early_initcall(). This makes sure it will
be called before all other cpus are online and therfore saves us a lot of
pointless smp_call_function() calls.
The control register settings will be forwarded to the other cpus when they
will be brought online.
