[PATCH 0/4] KASan: print output directly to stderr

I recently hunted down a heap memory corruption and this was somewhat
complicated by KASan and dump_stack() themselves allocating memory
off the heap. This series switches them to directly write to the
consoles associated with stderr, while skipping the log.

Ahmad Fatoum (4):
  ARM: unwind: don't allocate while printing stack trace
  ARM64: backtrace: print stacktrace to stderr
  KASan: only print to stderr
  KASan: don't allocate memory while printing report
