ve: Virtualize sysinfo
Extracted from "Initial patch".
Signed-off-by: Kirill Tkhai <ktk...@virtuozzo.com>
(cherry picked from vz7 commit e55cd51304b3271a2adaf43de9b9a5a7be34541e)
Signed-off-by: Konstantin Khorenko <khore...@virtuozzo.com>
Port to vz8 notes:
* virtinfo_notifier_call (bc_fill_sysinfo()) is substituted by
direct call to si_meminfo_ve() and only for not VE0.
* "avenrun" is not virtualized yet - need to port first commit
715f311fdb4a ("sched: Account task_group::cpustat,taskstats,avenrun")
* ve_struct.real_start_time is u64 now instead of timespec
