Subject: GNU C Library master sources branch master updated. glibc-2.26-555-g09c76a7
This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".

The branch, master has been updated
       via  09c76a74099826f4c6e1c4c431d7659f78112862 (commit)

commit 09c76a74099826f4c6e1c4c431d7659f78112862
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

    Linux: Consolidate {RTLD_}SINGLE_THREAD_P definition
    
    Current GLIBC has two ways to implement the single thread optimization
    on syscalls to avoid calling the cancellation path: either by using
    global variables (__{libc,pthread}_multiple_thread) or by accessing
    the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB).  Both the
    variables and the macros to acces its value are defined in the
    architecture sysdep-cancel.h header.
    
    This patch consolidates its definition on only one header,
    sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define
    (SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer
    to use the global variables instead of the TCB field.  This is an
    optimization, so if the architecture does not define it, the TCB
    method will be used as default.
    
    Checked on x86_64-linux-gnu and on a build with major touched
    ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf,
    hppa-linux-gnu, i686-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu,
