Changes in v4: o Squash a minor commit (per Borislav Petkov) o Change some comment text (per Borislav Petkov) o Add some acks
This patch set is a dependency of the generic red-black tree patch set, which I have now split up into three smaller sets and is based off of linux-next.
The major aim of this patch set is to cleanup compiler-gcc*.h and improve the manageability of of compiler features at various versions (when they are broken, etc.), add some needed features to bug.h and clean that up as well.
compiler-gcc*.h o Introduce GCC_VERSION - (e.g., gcc 4.7.1 becomes 40701) o Reorder all features based upon the version introduced (readability) o Change all version checks to use GCC_VERSION o Remove redundant __linktime_error
bug.h o Improve BUILD_BUG_ON(expr) - now generates compile-time error post-gcc-4.4 o Remove duplicate error messages in some cases. o Introduce BUILD_BUG_ON_MSG and clean up the implementations of the BUILD_BUG* macros.
