The generic slowpath WARN implementation prints a backtrace, but the report_bug() based implementation does not, opting to print the registers instead which is generally not as useful. Ideally, report_bug() should be fixed to make the behaviour more consistent, but in the meantime this patch generates a backtrace directly from the arm64 backend instead so that this functionality is not lost with the migration to report_bug(). As a side-effect, the backtrace will be outside the oops end marker, but that's hard to avoid without modifying generic code. This patch can go away if report_bug() grows the ability in the future to generate a backtrace directly or call an arch hook at the appropriate time.
