Subject: [PATCH v12 10/10] arm64: Select HAVE_RELIABLE_STACKTRACE
Date: Mon,  3 Jan 2022 10:52:12 -0600	[thread overview]
Message-ID: <20220103165212.9303-11-madvenka@linux.microsoft.com> (raw)
In-Reply-To: <20220103165212.9303-1-madvenka@linux.microsoft.com>

From: "Madhavan T. Venkataraman" <madvenka@linux.microsoft.com>

Select HAVE_RELIABLE_STACKTRACE in arm64/Kconfig to allow
arch_stack_walk_reliable() to be used.

Note that this is conditional upon STACK_VALIDATION which will be added
when frame pointer validation is implemented (say via objtool).
