2e4cf77897
The new cond var implementation (ed19993b5b) removed all the
__ASSUME_{REQUEUE_PI,FUTEX_LOCK_PI} internal usage so there is no
need to keep defining it. This patch removes all USE_REQUEUE_PI
and __ASSUME_REQUEUE_PI. It is as follow up from BZ#18463.
Checked with a build for x86_64-linux-gnu, arm-linux-gnueabhf,
m68-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu.
* nptl/pthreadP.h (USE_REQUEUE_PI): Remove ununsed macro.
* sysdeps/unix/sysv/linux/arm/kernel-features.h
(__ASSUME_REQUEUE_PI): Likewise.
* sysdeps/unix/sysv/linux/kernel-features.h
(__ASSUME_REQUEUE_PI): Likewise.
* sysdeps/unix/sysv/linux/m68k/kernel-features.h
(__ASSUME_REQUEUE_PI): Likewise.
* sysdeps/unix/sysv/linux/mips/kernel-features.h
(__ASSUME_REQUEUE_PI): Likewise.
* sysdeps/unix/sysv/linux/sparc/kernel-features.h
(__ASSUME_REQUEUE_PI): Likewise.
