7ba9bc6338 Kernel/aarch64: Remove static from dump_registers 
This allows the function to be called from other translation units, in
particular this allows the CrashHandler.cpp file to be shared between
aarch64 and x86_64.

7be7324287 Kernel/aarch64: Set correct ExecutionMode of PageFault 
Adds a helper to aarch64/Registers.h to factor out the exception class
encoding.

ecf45e191e Kernel/aarch64: Handle instruction aborts 
To detect instruction aborts, a helper to Registers.h is added, and used
in Interrupts.cpp. Additionally, the PageFault class gets a setter to
set the PageFaults m_is_instruction_fetch bool, and is also used in
Interrupts.cpp.

5f85f1abaa Kernel: Simplify (un)registering interrupt logic 
Lose a level of indentation and remove a superfluous `handler_slot`
check.

91db482ad3 Kernel: Reorganize Arch/x86 directory to Arch/x86_64 after i686 removal 
No functional change.

9b3db63e14 Kernel: Rename GenericInterruptHandler "invoking count" to "call count" 2022-11-19 15:39:30 +01:00

dfee6f73d2 Kernel: Replace VERIFY_NOT_REACHED with TODO_AARCH64 
This makes it easier to differentiate between cases where certain
functionality is not implemented vs. cases where a code location
should really be unreachable.

3cf8d3361e Kernel: Add support for handling interrupts on aarch64 
There is currently some code duplication between the aarch64
implementation and the x86 one, but this initial implementation works
for now. :^)

cbe1717181 Kernel: Rename idt_init() to initialize_interrupts() 
Also move the function out of the x86/Interrupts.h file into the generic
Interrupts.h file and add a stub for aarch64.

2fd5e9f729 Kernel: Add GenericInterruptHandler.cpp to aarch64 build 
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.
