Subject: [platforms: PATCH v2 03/12] Marvell/Armada: Armada70x0Lib: Terminate call stack list at entry
Date: Wed, 11 Oct 2017 12:15:30 +0200 [thread overview]
Message-ID: <1507716939-31798-4-git-send-email-mw@semihalf.com> (raw)
In-Reply-To: <1507716939-31798-1-git-send-email-mw@semihalf.com>
From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
To avoid dereferencing junk when walking the call stack in exception
handlers (which may prevent us from getting a full backtrace), set
the frame pointer to 0x0 when first entering UEFI.
