Andreas Kling 11eee67b85 Kernel: Make self-contained locking smart pointers their own classes
Until now, our kernel has reimplemented a number of AK classes to
provide automatic internal locking:

- RefPtr
- NonnullRefPtr
- WeakPtr
- Weakable

This patch renames the Kernel classes so that they can coexist with
the original AK classes:

- RefPtr => LockRefPtr
- NonnullRefPtr => NonnullLockRefPtr
- WeakPtr => LockWeakPtr
- Weakable => LockWeakable

The goal here is to eventually get rid of the Lock* classes in favor of
using external locking.

Liav A 0810c1b972 Kernel/Storage: Introduce basic abstraction layer for ATA components
This abstraction layer is mainly for ATA ports (AHCI ports, IDE ports).
The goal is to create a convenient and flexible framework so it's
possible to expand to support other types of controller (e.g. Intel PIIX
and ICH IDE controllers) and to abstract operations that are possible on
each component.

Currently only the ATA IDE code is affected by this, making it much
cleaner and readable - the ATA bus mastering code is moved to the
ATAPort code so more implementations in the near future can take
advantage of such functionality easily.

In addition to that, the hierarchy of the ATA IDE code resembles more of
the SATA AHCI code now, which means the IDEChannel class is solely
responsible for getting interrupts, passing them for further processing
in the ATAPort code to take care of the rest of the handling logic.

sin-ack 3f3f45580a Everywhere: Add sv suffix to strings relying on StringView(char const*)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).

No functional changes.

Brian Gianforcaro 6b85b358f8 Kernel: Unify Kernel task names for consistency
This change unifies the naming convention for kernel tasks.

The goal of this change is to:

- Make the task names more descriptive, so users can more
  easily understand their purpose in System Monitor.

- Unify the naming convention so they are consistent.

Sam Atkins c6a97ea843 Kernel: Mark kernel smart-pointer classes as [[nodiscard]]
And cast the unused return values to void.

Andreas Kling c922a7da09 Kernel: Rename ScopedSpinlock => SpinlockLocker
This matches MutexLocker, and doesn't sound like it's a lock itself.

Brian Gianforcaro c8b6bd4b97 Kernel: Mark WorkQueue initailzation functions as UNMAP_AFTER_INIT 2021-06-09 10:57:51 +02:00
Gunnar Beutner e9898a6031 Kernel: Use plain Function objects for the WorkQueue
The WorkQueue class previously had its own inline storage functionality
for function pointers. With the recent changes to the Function class
this is no longer necessary.

Linus Groh 649d2faeab Everywhere: Use "the SerenityOS developers." in copyright headers
We had some inconsistencies before:

- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."

I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.

By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).

Brian Gianforcaro 1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

Tom 20cccda731 Kernel: Add simplistic work queues
We can't use deferred functions for anything that may require preemption,
such as copying from/to user or accessing the disk. For those purposes
we should use a work queue, which is essentially a kernel thread that
may be preempted or blocked.
