Peter Collingbourne ebc78cc852 Switch to the new kernel API for obtaining fault address tag bits. ... The discussion on LKML is converging on v16 of the fault address tag bits patch [1]. In this version of the patch the presence of the tag bits in si_addr is controlled by a sa_flags bit, and a protocol is introduced to allow userspace to detect kernel support for sa_flags bits. Update the tombstone signal handler to use this API to read the tag bits, update the interceptors in libsigchain to implement the flag support detection protocol and hide the tag bits in si_addr from chained signal handlers that did not request them to match the kernel behavior.
