Add a new flag to /etc/ttys: onifconsole. This is equivalent to "on" if the device is an active kernel console and "off" otherwise. This is designed to allow serial-booting x86 systems to provide a login prompt on the serial line by default without providing one on all systems by default. Set this flag on x86 systems for ttyu0.

Create a separate script to generate osreldate.h rather than sourcing newvers.sh into a temporary subshell with inline make rules. Fixes PR 160646. Allow the path to the system source directory to be passed in to newvers.sh. Pass it in from include/Makefile. If it isn't passed in, fall back to the old logic of using dirname $0. Fixes PR 174422.

MFC r254465: Correct implementation of atomic_flag_test_and_set

2013-08-24T13:49:43Z

(This is a direct commit to stable/9 as atomic_flag_test_and_set_explicit is an inline function on HEAD and in a different file.)

- Simplify the implementation of atomic_compare_exchange_strong_explicit. - Evaluate the memory order argument in atomic_fetch_*_explicit macros. - Implement atomic_store_explicit using atomic_exchange_explicit instead of a plain assignment. MFC r241190: Define clang feature test macro __has_extension. It's used in stdatomic.h. MFC r254497: Change the return type of the fallback implementation of the atomic_compare_exchange_* macros in stdatomic.h to _Bool.

MFC r251192: Fix misspelling of structure field name.

- Make C11 atomic macros usable in expressions: - Replace do-while statements with void expressions. - Wrap __asm statements in statement expressions. - Make the macros function-like: - Evaluate all arguments exactly once. - Make sure there's a sequence point between evaluation of the arguments and the function body. Arguments should be evaluated before any memory barriers. - Fix use of __atomic_is_lock_free built-in. It requires the address of an atomic variable as second argument. Use this built-in on clang as well because clang's __c11_atomic_is_lock_free only takes the size of the variable into account. - In atomic_exchange_explicit put the barrier before instead of after the __sync_lock_test_and_set call.
