2012-10-09rbtree: adjust node color in __rb_erase_color() only when necessaryMichel Lespinasse1-0/+1
In __rb_erase_color(), we were always setting a node to black after exiting the main loop. And in one case, after fixing up the tree to satisfy all rbtree invariants, we were setting the current node to root just to guarantee a loop exit, at which point the root would be set to black. However this is not necessary, as the root of an rbtree is already known to be black. The only case where the color flip is required is when we exit the loop due to the current node being red, and it's easiest to just do the flip at that point instead of doing it after the loop.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare2-2/+2
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

2012-10-03perf tools: Convert to BACKTRACE_SUPPORTNamhyung Kim2-7/+7
For building perf without stack backtrace debug, we can set NO_BACKTRACE=1 as a argument of make. It then defines NO_BACKTRACE macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable and add _SUPPORT suffix for consistency.

We want to reduce the impact that each of the builtins has on perf as a whole, so use the superclassing of perf_tool mechanizm to move its config knobs to the stack, so that only if we use that tool, its impact will be felt. In this case is more about consistency, as the impact of this tool is minimal.
