This is bad design. But it fails if mapped, since something overwrites KernelHeap.

Kernel: Guard against recursive panics
...
Previously, when we panicked (page-fault for example) while dumping a kernel panic, it would just loop over and over again.
Now, we check if we were already in a panic, and limit the dump:
- No stack trace.
- Only a few registers.
- Only serial (since we can page fault while writing to the framebuffer)
This should make recursive panics much more difficult to achieve.
If we page-fault while writing to console, we don't even see a panic (not even in serial) and eventually triple-fault.
So this patch is actually more user-friendly.
