create demand-paging mapping in case of MAP_SHARED
...
On current McKernel, only mappings for demand paging can be shared.
Therefore, if MAP_SHARED and MAP_ANONYMOUS are specified and
anon_on_demand is disabled, then mmap(2) should create a mapping which
is for demand paging and is entirely populated with physical pages.

vsyscall: send SIGSEGV to the caller if syscall fails
...
On CentOS 7 (RHEL 7?), "errno" isn't set when vsyscall_gettimeofday
fails. So, in such case, vsyscall_gettimeofday send SIGSEGV to the
caller to report failure of gettimeofday operation.

releasing the runq lock after loading page tables but before the actual
