* Update to improved x86 Feather-Trace triggersBjoern Brandenburg2012-06-26
| | | | | | | | | | This patch imports recent upstream changes in Feather-Trace that reduce register pressure around Feather-Trace triggers. References: Commits 00713b8 and 225d734 in Feather-Trace. https://github.com/brandenburg/feather-trace/commit/00713b878636867ce07291c588509b38fa5bf152 https://github.com/brandenburg/feather-trace/commit/225d7348a08682cd87f72b127142bdfd6c0c7890
* Make __ARCH_HAS_FEATHER_TRACE a proper CONFIG_ variable.Bjoern B. Brandenburg2010-05-30
| | | | | | | | | The idea of the Feather-Trace default implementation is that LITMUS^RT should work without a specialized Feather-Trace implementation present. This was actually broken. Changes litmus/feather_trace.h to only include asm/feather_trace.h if actually promised by the architecture.
