This is a note to let you know that I've just added the patch titled perf build: Define YYNOMEM as YYNOABORT for bison < 3.81 to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: perf-build-define-yynomem-as-yynoabort-for-bison-3.8.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d77bea4b24c17e826c412d44d957fa663ff2e01e Author: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> Date: Fri Jul 28 17:26:54 2023 -0300 perf build: Define YYNOMEM as YYNOABORT for bison < 3.81 [ Upstream commit 88cc47e24597971b05b6e94c28a2fc81d2a8d61a ] YYNOMEM was introduced in bison 3.81, so define it as YYABORT for older versions, which should provide the previous perf behaviour.
