[PATCH 5/5] RISC-V: stacktrace: output stack traces to standard error

[Ahmad Fatoum]

KASAN splats are currently split between standard output and standard
error, which looks ok, when both are enabled on the same consoles, but
is difficult to follow when mapping standard out/err to different
consoles. Let's move all stack trace dumping to standard error. This is
already the case for ARM.
