[PATCH v14 7/7] arm64: Select HAVE_RELIABLE_STACKTRACE

From: madvenka
Date: Wed Apr 13 2022 - 10:06:17 EST


From: "Madhavan T. Venkataraman" <madvenka@xxxxxxxxxxxxxxxxxxx>

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).
