[Crash-utility] [ANNOUNCE] crash gcore command, version 1.2.2 is released

[HATAYAMA Daisuke]

This is the release of crash gcore command, version 1.2.2.

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.

 - Tested on RHEL5.10.
