* ARM64: backtrace: print stacktrace to stderrAhmad Fatoum2023-09-121-3/+3
| | | | | | | | | | | Rule of thumb is to print interactive output to stdout and status messages to stderr. A stack dump falls into the latter category and part of the stack trace is already printed to stderr, because of use of the logging functions, which always prints there.

* ARM: aarch64: implement stacktracesSascha Hauer2018-03-291-0/+86
Implement stacktraces as a great debugging aid. On aarch64 this is cheap enough to be enabled unconditionally. Unwinding code is taken from the Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
