musl: mips: add vdso support
vdso support is available on mips starting with kernel 4.4, see kernel commit a7f4df4e21 "MIPS: VDSO: Add implementations of gettimeofday() and clock_gettime()" for details. These are my micro benchmark results for 1.000.000 calls to clock_gettime(CLOCK_MONOTONIC, &tp) without vdso: root@OpenWrt:/# time ./vdso-test real 0m 0.95s user 0m 0.24s sys 0m 0.70s with vdso: root@OpenWrt:/# time /usr/bin/vdso-test real 0m 0.35s user 0m 0.34s sys 0m 0.00s Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 48466
