2019-06-26vdso: Remove superfluous #ifdef __KERNEL__ in vdso/datapage.hCatalin Marinas1-4/+0
With the move to UAPI headers, such #ifdefs are no longer necessary.

2019-06-22timekeeping: Provide a generic update_vsyscall() implementationVincenzo Frascino1-0/+11
The new generic VDSO library allows to unify the update_vsyscall[_tz]() implementations. Provide a generic implementation based on the x86 code and the bindings which need to be implemented in architecture specific code. [ tglx: Moved it into kernel/time where it belongs.

2019-06-22lib/vdso: Provide generic VDSO implementationVincenzo Frascino1-0/+56
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.

2019-06-22vdso: Define standardized vdso_datapageVincenzo Frascino1-0/+93
Define a common formet for the vdso datapage as a preparation for sharing the VDSO implementation as a generic library. The datastructures are based on the current x86 layout.
