Evaluate LDFLAGS_BUILD_ID (which involves invoking the compiler) only once instead of over and over. This provides a ~20% reduction in null build time with x86 allnoconfig: $ make allnoconfig && make -j8 $ perf stat -r5 -e sched:sched_process_exec make -j8 - 2 119 sched:sched_process_exec + 1 878 sched:sched_process_exec - 1,238817018 seconds time elapsed + 0,971020553 seconds time elapsed Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
