[Crash-utility] Heads up: crash command errors with 2.6.24 kernels

It should be noted that while version 4.0-4.11 will at least allow a crash session to initialize, there are several other 2.6.24 related kernel changes that have broken several key commands. Among them, at least on x86_64 kernels: 1. "kmem -[sS]" fails due to changes in the CONFIG_SLUB code between 2.6.22 and 2.6.24. 2. "kmem <address>" doesn't work at all. 3. "kmem -n" fails to show any pgdat-node related information. 4. "kmem -f" doesn't work at all. 5. "kmem -i" doesn't work at all. 6. "runq" for the CFS scheduler no longer shows any queued tasks, but only the relevant structure addresses. 7. The kernel's use of a virtual mem_map array on x86_64 is not handled, and this may lead to other page struct related errors. Dave
