commit 01f8eac224421f07f28f91cc05db7459ea433ea4
Author: Adhemerval Zanella <azanella@linux.vnet.ibm.com>
Date: Wed Mar 26 13:48:00 2014 -0500
Move __PTHREAD_SPINS definition to architecture specific header
This patch moves the __PTHREAD_SPINS definition to arch specific header
since pthread_mutex_t layout is also arch specific. This leads to no
need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the
undefined compiler warning.
Conflicts:
nptl/sysdeps/unix/sysv/linux/x86/bits/pthreadtypes.h
(Textual conflict due to glibc-rh841653-3.patch.)
sysdeps/unix/sysv/linux/microblaze/nptl/bits/pthreadtypes.h
(No microblaze port in our tree; file removed manually.)
In addition, nptl/sysdeps/unix/sysv/linux/powerpc/bits/pthreadtypes.h
was adjusted for the separate HTM backport in glibc-rh731835-0.patch.
