Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '

s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

-print)
and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \
sysdeps/csky/configure \

Add:
int pthread_cond_clockwait (pthread_cond_t *cond,
pthread_mutex_t *mutex,
clockid_t clockid,
const struct timespec *abstime)
which behaves just like pthread_cond_timedwait except it always measures
abstime against the supplied clockid. Currently supports CLOCK_REALTIME
and
CLOCK_MONOTONIC and returns EINVAL if any other clock is specified.
Includes feedback from many others. This function was originally
proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group
preferred the new name.
* nptl/Makefile: Add tst-cond26 and tst-cond27
* nptl/Versions (GLIBC_2.30): Add pthread_cond_clockwait

clockid parameter and comment describing why we don't need to
check
its value. Use that value when calling
futex_abstimed_wait_cancelable rather than reading the clock
from
the flags. (__pthread_cond_wait): Pass unused clockid parameter.
(__pthread_cond_timedwait): Read clock from flags and pass it to
__pthread_cond_wait_common. (__pthread_cond_clockwait): Add new
function with weak alias from pthread_cond_clockwait.

* comment
was provided by Carlos O'Donell.
