Konstantin Belousov 5e27d79314 Split kerne timekeep ABI structure vdso_sv_tk out of the struct ... sysentvec. This allows the timekeep data to be shared between similar ABIs which cannot share sysentvec. Make the timekeep_push_vdso() tick callback to the timekeep structures instead of sysentvecs. If several sysentvec share the vdso_sv_tk structure, we would update the userspace data several times on each tick, without the change. Only allocate vdso_sv_tk in the exec_sysvec_init() sysinit when sysentvec is marked with the new SV_TIMEKEEP flag. This saves allocation and update of unneeded vdso_sv_tk for ABIs which do not provide userspace gettimeofday yet, which are PowerPCs arches right now. Make vdso_sv_tk allocator public, namely split out and export alloc_sv_tk() and alloc_sv_tk_compat32(). ABIs which share timekeep data now can allocate it manually and share as appropriate.
