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 to be enabled and used internally on glibc. 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. Checked on aarch64-linux-gnu, arm-linux-gnueabihf, i386-linux-gnu, mips64-linux-gnu, powerpc64le-linux-gnu, s390x-linux-gu, sparc64-linux-gnu, and x86_64-linux-gnu. * sysdeps/powerpc/powerpc32/backtrace.c (is_sigtramp_address, is_sigtramp_address_rt): Use HAVE_SIGTRAMP_{RT}32 instead of SHARED. * sysdeps/powerpc/powerpc64/backtrace.c (is_sigtramp_address): Likewise. * sysdeps/unix/sysv/linux/aarch64/init-first.c: Remove file. * sysdeps/unix/sysv/linux/aarch64/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/arm/init-first.c: Likewise. * sysdeps/unix/sysv/linux/arm/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/mips/init-first.c: Likewise. * sysdeps/unix/sysv/linux/mips/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/i386/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/s390/init-first.c: Likewise. * sysdeps/unix/sysv/linux/s390/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/sparc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/sparc/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/x86/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Define value based on kernel exported name. * sysdeps/unix/sysv/linux/arm/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETCPU_VSYSCALL, HAVE_TIME_VSYSCALL, HAVE_GET_TBFREQ, HAVE_SIGTRAMP_RT64, HAVE_SIGTRAMP_32, HAVE_SIGTRAMP_RT32): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/dl-vdso.h (VDSO_NAME, VDSO_HASH): Define to invalid names if architecture does not define them.
