> ChangeLog:
> 
>  - Now gcore collects and writes ELF note segments in O(1) memory
>    consumption with regard to the number of threads. The implementation
>    so far had created ELF note segments for all the threads as a list
>    at the same time, and so memory consumption had grown in proportion
>    to the number of threads. In contrast, new implementation writes
>    ELF note segments one by one. Without this change, gcore could fail
>    abnormally if specified process consists of threads more than tens of
>    thousands, with the message: "gcore: cannot allocate any more memory!".

>  - Fix the address of vdso virtual address in x86_64 compat mode by using
>    fixed VDSO_HIGH_BASE, not by vma->vm_mm->context.vdso. Without this
>    fix, access to vdso page fails in x86_64 compat mode and vdso page
>    fails to be collected in generated process core dump.
