Browse source 
Symbols now use the K_ prefix which is now standard for the
unified kernel. Legacy support for these symbols is retained
to allow existing applications to build successfully.

@ -101,14 +101,15 @@ handling overhead involved in auto-tagging threads, it is possible to
pre-tag a thread using one of the techniques listed below.
* A statically-spawned x86 thread can be pre-tagged by passing the
:c:macro:`USE_FP` or :c:macro:`USE_SSE` option to
:c:macro:`K_FP_REGS` or :c:macro:`K_SSE_REGS` option to
:c:macro:`K_THREAD_DEFINE()`.
* A dynamically-spawned x86 thread can be pre-tagged by passing the
:c:macro:`USE_FP` or :c:macro:`USE_SSE` option to :c:func:`k_thread_spawn()`.
:c:macro:`K_FP_REGS` or :c:macro:`K_SSE_REGS` option to
:c:func:`k_thread_spawn()`.
* An already-spawned x86 thread can pre-tag itself once it has started
by passing the :c:macro:`USE_FP` or :c:macro:`USE_SSE` option to
by passing the :c:macro:`K_FP_REGS` or :c:macro:`K_SSE_REGS` option to
:c:func:`k_float_enable()`.
If an x86 thread uses the floating point registers infrequently it can call
