      gcov: add support for GCC 10.1 · 40249c69
      Peter Oberparleiter authored
      Using gcov to collect coverage data for kernels compiled with GCC 10.1
      causes random malfunctions and kernel crashes.  This is the result of a
      changed GCOV_COUNTERS value in GCC 10.1 that causes a mismatch between
      the layout of the gcov_info structure created by GCC profiling code and
      the related structure used by the kernel.
      
      Fix this by updating the in-kernel GCOV_COUNTERS value.  Also re-enable
      config GCOV_KERNEL for use with GCC 10.

      This happens because Kyber doesn't track flush requests, so
      kyber_finish_request() reads a garbage domain token. Only call the
      scheduler's requeue_request() hook if RQF_ELVPRIV is set (like we do for
      the finish_request() hook in blk_mq_free_request()). Now that we're
      handling it in blk-mq, also remove the check from BFQ.
