> ChangeLog:
> 
>  - Fix failure of coredump at accessing memory for VSYSCALL page due
>    to wrong conversion of uvtop which wrongly treats address
>    VSYSCALL_START as belongs to kernel direct mapping region. This fix
>    executes uvtop in verbose mode to make it always paging and
>    retrieves the correct physical address from its output. Without
>    this fix, VSYSCALL page fails to be collected and core dump process
>    is aborted; though VSYSCALL page is done in the last so allmost all
>    corefile is already generated.

>  - Skip page-faulted pages by lseek() rather than writing zero-filled
>    pages. By this, generated core file has holes in the corresponding
>    positions for each page-faulted pages if filesystem supports sparse
>    files. This is highly useful when the target process has huge
>    virtual memory space such as qemu process that has huge physical
>    memory of KVM guest machine.

>  - Fix the bug that filter for hugepage shared/private memory can
>    depend on flags other than HP or HS flags. This was introduced at
>    the introduction of VM_DONTDUMP where VM_RESERVED flag was
>    removed. At the time, there was a check to see if VM_REESRVED flag
>    was set after a check to see if VM_HUGETLB. But the latter check
>    was not changed when the former check was removed.
