Subject: [PATCH 3/5] x86/mm: Initialize text poking earlier
Date: Tue, 25 Oct 2022 22:06:59 +0200 [thread overview]
Message-ID: <20221025201057.881703081@infradead.org> (raw)
In-Reply-To: 20221025200656.951281799@infradead.org
Move poking_init() up a bunch; specifically move it right after
mm_init() which is right before ftrace_init().
This will allow simplifying ftrace text poking which currently has
a bunch of exceptions for early boot.
