Hi Sterling, these three patches fix bits of xtensa libgcc related to stack unwinding. They fix a number of uClibc-ng NPTL thread cancellation and cleanup tests, particularly uClibc-ng 1.0.5 tests nptl/tst-cancelx4, nptl/tst-cancelx16, nptl/tst-cancelx18, nptl/tst-cancelx20, nptl/tst-cancelx21, nptl/tst-cleanupx1, nptl/tst-cleanupx3, nptl/tst-oncex3, nptl/tst-oncex4.
