ff500a623d linux: Add support for clock_gettime64 vDSO
No architecture currently defines the vDSO symbol.  On architectures
with 64-bit time_t the HAVE_CLOCK_GETTIME_VSYSCALL is renamed to
HAVE_CLOCK_GETTIME64_VSYSCALL, it simplifies clock_gettime code.

b8a7c7da4e Refactor vDSO initialization code
Linux vDSO initialization code the internal function pointers require a
lot of duplicated boilerplate over different architectures.  This patch
aims to simplify not only the code but the required definition to enable
a vDSO symbol.

The changes are:

  1. Consolidate all init-first.c on only one implementation and enable
     the symbol based on HAVE_*_VSYSCALL existence.

  2. Set the HAVE_*_VSYSCALL to the architecture expected names string.

  3. Add a new internal implementation, get_vdso_mangle_symbol, which
     returns a mangled function pointer.

Currently the clock_gettime, clock_getres, gettimeofday, getcpu, and time
are handled in an arch-independent way, powerpc still uses some
arch-specific vDSO symbol handled in a specific init-first implementation.

b8386c2859 Remove PREPARE_VERSION and PREPARE_VERSION_KNOW
This patch removes the PREPARE_VERSION and PREPARE_VERSION_KNOW macro
and uses a static inline function instead, get_vdso_symbol.  Each
architecture that supports vDSO must define the Linux version and its
hash for symbol resolution (VDSO_NAME and VDSO_HASH macro respectively).

It also organizes the HAVE_*_VSYSCALL for mips, powerpc, and s390 to
define them on a common header.

The idea is to require less code to configure and enable vDSO support
for newer ports.  No semantic changes are expected.

d665367f59 linux: Enable vDSO for static linking as default (BZ#19767)
This patch assumes static vDSO is supported as default, it is now supported
on all current architectures that support vDSO.  It allows removing both

ALWAYS_USE_VSYSCALL).

09c76a7409 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.

60f9423b6b Consolidate Linux send implementation
This patch consolidates the send Linux syscall implementation on
sysdeps/unix/sysv/linux/send{to}.c.  The changes are:

  1. Remove send from auto-generation syscalls.list on the architecture
     that uses __NR_send.
  2. Define __NR_send for architectures that supports it. It was done instead
     of defining in default kernel-features.h because current Linux practice
     for new ports are to implement only __NR_sendto [1] and it will
     require adding new kernel-features for ports that do not require it
     (aarch64 for instance).
  3. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use
     __NR_sendto for send generation based on __ASSUME_SENDTO_SYSCALL.

42de7e2029 aarch64: fix errno address calculation in SYSCALL_ERROR_HANDLER
This patch fixes the last regression in LTP lite scenario (mmap16) comparing
to lp64 in my source trees [1, 2]. The fix has been suggested back in 2015 [3]
but was never applied.

Checked on aarch64-linux-gnu.

	* sysdeps/unix/sysv/linux/aarch64/sysdep.h: use PTR_REG() for offset
	calculation in SYSCALL_ERROR_HANDLER().

97554e4382 Consolidate gettimeofday across aarch64/s390/tile
This patch removes the architecture specific gettimeofday implementation
to use the vDSO symbol and consolidate it on a common Linux one.
Similar to clock_gettime and clock_getres vDSO implementation, each port
that supports gettimeofday through vDSO should just implement INLINE_VSYSCALL
to access the symbol and define HAVE_{GETTIME,GETRES}_VSYSCAL as 1.

f534255e4d Consolidate vDSO macros and usage
This patch consolidate the Linux vDSO define and usage across all ports
that uses it.  The common vDSO definitions and calling through
{INLINE/INTERNAL}_VSYSCALL macros are moved to a common header
sysdep-vdso.h and vDSO name declaration and prototype is defined
using a common macro.

Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them
for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will
reflect in code changes.  For ports that already implement pointer
mangling/demangling in vDSO system (i386, x32, x86_64) this patch
is mainly a code refactor.

Checked on x32, x86_64, x32, ppc64le, and aarch64.

1670e207c5 aarch64: Rely on syscalls preserving registers
In several cases we've had asm routines rely on syscalls not clobbering
call-clobbered registers, and that's now deemed ABI.  So take advantage
of this in the INLINE_SYSCALL path as well.

Shrinks libc.so by about 1k.

fede7a5ffa aarch64: Remove inaccurate comment from sysdep.h
This comment appears to have been copied from the ARM port where it
makes more sense.

	* sysdeps/unix/sysv/linux/aarch64/sysdep.h: Remove
	inaccurate comment.

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.
