Subject: [PATCH v14 7/7] arm64: Select HAVE_RELIABLE_STACKTRACE
Date: Wed, 13 Apr 2022 09:05:28 -0500	[thread overview]
Message-ID: <20220413140528.3815-8-madvenka@linux.microsoft.com> (raw)
In-Reply-To: <20220413140528.3815-1-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).
