Now that the Spinlock code is not dependent on architectural specific
code anymore, we can move it back to the Locking folder. This also means
that the Spinlock implemenation is now used for the aarch64 kernel.
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.
These 2 classes currently contain much code that is x86(_64) specific.
Move them to the architecture specific directory. This also allows for a
simpler implementation for aarch64.
This requires us to add an Interrupts.h file in the Kernel/Arch
directory, which includes the architecture specific files.
The commit also stubs out the functions to be able to compile the
aarch64 Kernel.
This allows us to use the AK formatting functions in the aarch64 Kernel.
Also add FIXME to make sure that this file will be removed when the
proper abstractions are in place in the normal Kernel/kprintf.cpp.
