This patch removes the definition of __ASSUME_GETCPU_SYSCALL. In fact this macro is unused, probably since: commit dd26c44403582fdf10d663170f947dfe4b3207a0 Author: Adhemerval Zanella <adhemerval.zanella@linaro.com> Date: Wed Apr 22 14:21:39 2015 -0300 Consolidate sched_getcpu so it could have been removed even without the move to 3.2 as minimum kernel version on x86_64. Tested for x86_64. 2017-05-08 Joseph Myers <joseph@codesourcery.com> * sysdeps/unix/sysv/linux/x86_64/kernel-features.h (__ASSUME_GETCPU_SYSCALL): Remove macro.
