lib/vdso: use "grep -E" instead of "egrep"

2022-12-08T10:22:59Z

commit 8ac3b5cd3e0521d92f9755e90d140382fc292510 upstream. The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the vdso Makefile to use "grep -E" instead.

lib/vdso: Provide generic VDSO implementation

2019-06-22T19:21:05Z

In the last few years the kernel gained quite some architecture specific vdso implementations which contain very similar code. Introduce a generic VDSO implementation of gettimeofday() which will be shareable between architectures once they are converted over. The implementation is based on the current x86 VDSO code.
