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)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
$(find $(git ls-files) -prune -type f \
! -name '*.po' \
! -name 'ChangeLog*' \
! -path COPYING ! -path COPYING.LIB \
! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
! -path manual/texinfo.tex ! -path scripts/config.guess \

! -path INSTALL ! -path locale/programs/charmap-kw.h \

! '(' -name configure \
-execdir test -f configure.ac -o -f configure.in ';' ')' \
! '(' -name preconfigure \
-execdir test -f preconfigure.ac ';' ')' \
-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 \
sysdeps/hppa/configure \
sysdeps/riscv/configure \
sysdeps/unix/sysv/linux/csky/configure
# Omit changes that caused a pre-commit check to fail like this:
# remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
git checkout -f \
sysdeps/powerpc/powerpc64/ppc-mcount.S \
sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
# Omit change that caused a pre-commit check to fail like this:
# remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline
git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

/*
|
|
* This is for COMPATIBILITY with Linux/x86 only. Linux/Alpha system
|
|
* calls return an error indication in a3. This allows arbitrary 64bit
|
|
* values to be returned in v0 (because negative values are not
|
|
* mistaken as error numbers). However, C allows only one value to
|
|
* be returned, so the interface below folds the error indication passed in
|
|
* a3 back into v0: it sets v0 to -errno if an error occurs. Thus,
|
|
* no negative 64bit numbers can be returned. To avoid this problem,
|
|
* use assembly stubs wherever possible/convenient.
|
|
*
|
|
* Usage:
|
|
*
|
|
* long syscall(syscall_number, arg1, arg2, arg3, arg4, arg5, arg6)
|
|
*
|
|
* syscall_number = the index of the system call we're invoking
|
|
* arg1-arg6 = up to 6 integer arguments to the system call
|
|
*
|
|
* We need to do some arg shifting: the kernel expects the
|
|
* syscall number in v0 and the first six args in a0-a5.
|
