Subject: [PATCH v2 19/24] selftests: mm: move fpregs printing
Date: Fri, 27 Oct 2023 19:08:45 +0100 [thread overview]
Message-ID: <20231027180850.1068089-20-joey.gouly@arm.com> (raw)
In-Reply-To: <20231027180850.1068089-1-joey.gouly@arm.com>
arm64's fpregs are not at a constant offset from sigcontext. Since this is
not an important part of the test, don't print the fpregs pointer on arm64.
