Fix for reading compressed kdump dumpfiles from systems with physical
|
|
memory located at extraordinarily high addresses. In a system with
|
|
a physical address range from 0x602770ecf000 to 0x6027ffffffff, the
|
|
crash utility fails during session initialization due to an integer
|
|
overflow, ending with the error message "crash: vmlinux and vmcore
|
|
do not match!".
