5a82c74822 Prefer https to http for gnu.org and fsf.org URLs 
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 \

      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \

      ! '(' -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:

f07d2ec8c0 Use libm_alias_double for aarch64. 
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes aarch64 libm function implementations use
libm_alias_double to define function aliases.

Tested with build-many-glibcs.py for aarch64-linux-gnu that installed
stripped shared libraries are unchanged by the patch.

5062680c60 aarch64: Implement math acceleration via builtins 
This patch converts asm statements into builtins for AArch64.  As an
example for the file sysdeps/aarch64/fpu/s_ceil.c, we convert the
function from

double
__ceil (double x)
{
  double result;
  asm ("frintp\t%d0, %d1" :
       "=w" (result) : "w" (x) );
  return result;
}

into

double
__ceil (double x)
{
  return __builtin_ceil (x);
}

Tested on aarch64-linux-gnu with gcc-4.9.4 and gcc-6.

	* sysdeps/aarch64/fpu/e_sqrt.c (ieee754_sqrt): Replace asm statements
	with __builtin_sqrt.

75eff3fe90 Relocate AArch64 from ports to libc. 
This patch moves the AArch64 port to the main sysdeps hierarchy.  The
move is essentially:

  git mv ports/sysdeps/aarch64 sysdeps/aarch64
  git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64

The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move.  The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
