*	Avoid PLT when calling __sched_getaffinity_new	H.J. Lu	2015-10-14	1	-0/+7
\| \| \| \| \| \| \| \| \| \| \|	This patch adds an internal entry for __sched_getaffinity_new so that __sched_getaffinity_old calls __sched_getaffinity_new without going through PLT. [BZ #18822] * sysdeps/unix/sysv/linux/sched_getaffinity.c (__sched_getaffinity_new): Add libc_hidden_proto and libc_hidden_def.

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT. INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error number returned from the majority of Linux kernels for which negating is a no-op with INTERNAL_SYSCALL_ERRNO.
