#2 crashinfo --checkstacks aborts

[Martin Moore]

"crashinfo --checkstacks" will abort on kernel version 4.18.0-477.10.1.el8_8.x86_64 (other versions not yet checked) with the following traceback:

crash64> crashinfo --checkstacks
Traceback (most recent call last):
File "/usr/local/lib/mpykdump64.so/progs/crashinfo.py", line 1548, in <module>
File "/usr/local/lib/mpykdump64.so/progs/crashinfo.py", line 1351, in checkAllStacks
File "/usr/local/lib/mpykdump64.so/progs/crashinfo.py", line 1315, in checkTaskStack

raise KeyError(msg)
KeyError: '<struct thread_struct=""> does not have a field <sp0>'</sp0></struct></module>

[Martin Moore]

This turned out to be two different aborts: one due to the relocation of restart_block from
thread_info to task_struct in kernel v4, and the other due to the removal of thread_struct.sp0 from x86_64 kernels starting with 4.14.9.
