Subject: Re: [PATCH v3] printk: allow increasing the ring buffer depending on the number of CPUs
Date: Sat, 14 Jun 2014 20:48:07 +0200 [thread overview]
Message-ID: <20140614184807.GE4841@wotan.suse.de> (raw)

It turns out we can't use num_possible_cpus() that early on boot, as
it hasn't yet been properly set, nor other helpers, a late setup for
big CPUs is therefore needed in order to use num_possible_cpus().
That also means we can use kzalloc() instead. I'll send a v4 and
I think we should test this a bit so will send as RFT.
