Modified Files: src/sys/arch/powerpc/include: mcontext.h ptrace.h types.h src/sys/arch/powerpc/powerpc: sig_machdep.c Log Message: Fix inconsistency b/w kernel and userland recognitions of TLS, as well as inconsistency whether it is biased or not in kernel. - Obsolete __lwp_settcb() in order to let kernel know new TLS address via _lwp_setprivate(2). Alternatively, we can call _lwp_setprivate(2) within __lwp_settcb() like mips, but it is just double handling; we adjust %r2 appropriately in _lwp_setprivate(2) via cpu_lwp_setprivate(). - Make sure that, like other ports, l_private represents address of tcb, not biased one as in %r2. This guarantees that the returned values from _lwp_getprivate(2) and __lwp_getprivate_fast() are always same. Also, we can obsolete PTRACE_LWP_GETPRIVATE() macro. Now, *_pl_private tests in tests/lib/libc/sys successfully pass, while no other tests become newly falling.
