This is v2 of the series posted at: http://lkml.kernel.org/r/cover.1651047542.git.naveen.n....@linux.vnet.ibm.com
For v2, the first patch is slightly modified to skip the loop, rather than depending on addr == 0 to do so. The second patch is updated to make this behavior be opt-in by architectures so that they can validate the read mcount locations. - Naveen Naveen N.
