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

-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 \

# Omit changes that caused a pre-commit check to fail like this:

git checkout -f \

This follows c45d78aac ('posix: Fix generic p{read,write}v buffer allocation
(BZ#22457)'), which made pwritev to use __mmap instead of __posix_memalign,
but didn't pass PROT_READ to it, while the pwrite() call does need to
read the data we have just copied over.
* sysdeps/posix/pwritev_common.c: Add PROT_READ to __mmap prot.

As described in BZ#22457 an interpose malloc can free an invalid
pointer for fallback preadv implementation. Fortunately this is
just and issue on microblaze-linux-gnu running kernels older than
3.15. This patch fixes it by calling mmap/unmap instead of
posix_memalign/ free.
Checked on microblaze-linux-gnu check with run-built-tests=no and
by using the sysdeps/posix implementation on x86_64-linux-gnu (just
for sanity test where it shown no regression).
[BZ #22457]
* sysdeps/posix/preadv_common.c (PREADV): Use mmap/munmap instead of
posix_memalign/free.
* sysdeps/posix/pwritev_common.c (PWRITEV): Likewise.

Currently all architectures but microblaze use wire-up syscall for
p{readv,write}v. Microblaze still uses the syscall emulation using
sysdep/posix/p{readv,writev}.c and it was reported in some ocasions
[1] [2] that it might have some issues with some linux specific
usage (mainly with O_DIRECT and the alignment requirement).
Although it is not an issue for virtually all the system, this
patch refactors the sysdeps/posix p{read,write}v syscall to avoid
such issue (by using posix_memalign on the buffer used on
p{read,write} call) and by refactoring it common files to avoid
the need check on defines to correct set the alias and internal
symbols.
