powerpc: Simplify vsyscall internal macros
This patch simplifies the powerpc internal macros for vDSO calls
by:
- Removing INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, used solely on
get_timebase_freq.
- Adjust INTERNAL_VSYSCALL_CALL_TYPE powerpc32 to follow powerpc64
argument ordering.
- Use HAVE_*_VSYSCALL instead of explicit strings.
- Make powerpc libc-vdso.h include generic implementation.
No semantic change expected, checked on powerpc-linux-gnu-power4,
powerpc64-linux-gnu, and powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/libc-vdso.h (VDSO_IFUNC_RET): Define if not
defined.
* sysdeps/unix/sysv/linux/powerpc/get_timebase_freq.c
(__get_timebase_freq): Remove use of
INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK.
(get_timebase_freq_fallback): New symbol.
* sysdeps/unix/sysv/linux/powerpc/gettimeofday.c (time): Use
HAVE_GETTIMEOFDAY_VSYSCALL.
* sysdeps/unix/sysv/linux/powerpc/time.c (gettimeofday): Use
HAVE_TIME_VSYSCALL.
* sysdeps/unix/sysv/linux/powerpc/libc-vdso.h: Include generic
implementation.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h
(INTERNAL_VSYSCALL_CALL_TYPE): Make calling convention similar to
powerpc64.
(INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK): Remove macro.
* .../sysv/linux/powerpc/powerpc64/sysdep.h
(INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK): Likewise.
* sysdeps/unix/sysv/linux/powerpc/sysdep.h
(HAVE_GETTIMEOFDAY_VSYSCALL): Define.
