hppa/vdso: Add wrappers for vDSO functions
The upcoming parisc (hppa) v6.11 Linux kernel will include vDSO support for gettimeofday(), clock_gettime() and clock_gettime64() syscalls for 32- and 64-bit userspace. The patch below adds the necessary glue code for glibc. Signed-off-by: Helge Deller <deller@gmx.de> Changes in v2: - add vsyscalls for 64-bit too
