From c484da9087632f2f1b4ab5a6cae4efcd09436d1d Mon Sep 17 00:00:00 2001 From: Sergey Bugaev Date: Wed, 15 Sep 2021 20:11:10 +0300 Subject: [PATCH] elf: Remove THREAD_GSCOPE_IN_TCB All the ports now have THREAD_GSCOPE_IN_TCB set to 1. Remove all support for !THREAD_GSCOPE_IN_TCB, along with the definition itself.
