Kernel: Add a pstat() system call
...
Not part of C or POSIX, but since there is no procfs right now, I thought it would be nice to have an interface to query process information.
It works like this: you pass the process ID and a pointer to a struct pstat (can be null).
If the process ID is -1, the kernel picks the process with the highest PID.
Then, if the pointer to a pstat struct is not null, the kernel fills it in with the process's information, and returns the process's PID.

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.
