8e2d0c8d5c Kernel: Do not return a null ref in Processor::current on aarch64 
Clang rejects binding a reference to a null pointer at compile-time.
Let's just crash explicitly, instead of waiting for a null dereference
to mess things up.

711a7104f3 Kernel: Handle invalid stack pointer during signal dispatch 
Instead of crashing the kernel, we simply terminate the process.

40f64d7379 Kernel: Dispatch handle-able signals instead of crashing if possible 
This matches the behaviour of the other *nixs and allows processes to
try and recover from such signals in userland.

f27bbec7b2 Kernel: Move incorrect early return in sys$mprotect 
Since we're iterating over multiple regions that interesect with the
requested range, just one of them having the requested access flags
is not enough to finish the syscall early.

a9e436c4a3 Kernel: Replace usages of SIGSTKFLT with SIGSEGV 
SIGSTKFLT is a signal that signifies a stack fault in a x87 coprocessor,
this signal is not POSIX and also unused by Linux and the BSDs, so let's
use SIGSEGV so programs that setup signal handlers for the common
signals could still handle them in serenity.

4ca39c7110 Kernel: Move the expand_range_to_page_boundaries helper to MemoryManager 
This helper can (and will) be used in more parts of the kernel besides
the mmap-family of syscalls.

ff6b43734c Kernel: Add Region::clear_to_zero

region.

5f95a1a7b7 LibC: Define the MADV_DONTNEED madvise advice macro 
This isn't actually implemented at the moment, but it is required for
wine to compile

fc13d0782f LibC: Make the madvise advice field a value instead of a bitfield 
The advices are almost always exclusive of one another, and while POSIX
does not define madvise, most other unix-like and *BSD systems also only
accept a singular value per call.

a5cec06135 Kernel: Handle string format error in page_fault_handler(..) :^)

4cc41ea186 Kernel: Add an error propagating KString::format(..) API :^) 
In the continuous effort of better handling OOM in the kernel,
we want to move away from all AK::String usage. One of the final
pieces left to accomplish this goal is replacing all of the usages
of `String::formatted` with something that can actually propagate
failure.

The StringBuilder API was enhanced in the recent past to propagate
failure and thus a slightly modified version of what exists in
`AK::format` will work well for implementing failable format with
`KString`.

e187207610 Kernel: Register Virtio console ports with device management 
Previously, Virtio console ports would not show up in `/sys/dev/char/`.
Also adds support to `SystemServer` to create more than one console
port device in `/dev/` in the multiport case.
