e529042895 Kernel: Remove reduntant kernel/user signal stacks. 
Due to the changes in signal handling m_kernel_stack_for_signal_handler_region
and m_signal_stack_user_region are no longer necessary, and so, have been
removed. I've also removed the similarly reduntant m_tss_to_resume_kernel.

e29fd3cd20 Kernel: Display virtual addresses as V%p instead of L%x 
The L was a leftover from when these were called linear addresses.

272bd1d3ef Kernel: Make crash dumps look aligned once again 
This broke with the recent changes to make printf hex fields behave
a bit more correctly.

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are. 
These types can be picked up by including <AK/Types.h>:

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

f6498bb0e9 Kernel: Make more crash info show up in dmesg. 
kprintf() shows up in dmesg, dbgprintf() does not.

8c0ae711d8 Kernel+LibC: Make page fault crashes a bit more readable. 
We'll now try to detect crashes that were due to dereferencing nullptr,
uninitialized malloc() memory, or recently free()'d memory.
It's not perfect but I think it's pretty good. :^)

Also added some color to the most important parts of the crash log,
and added some more modes to /bin/crash for exercising this code.

Fixes #243.

15bea7153a Kernel: Symbolicate the crash address too, not just the call stack. 
Also print it in shiny red to make it extra easy to spot. :^)
Fixes #244.

736092a087 Kernel: Move i386.{cpp,h} => Arch/i386/CPU.{cpp,h} 
There's a ton of work that would need to be done before we could spin up on
another architecture, but let's at least try to separate things out a bit.

Renamed from Kernel/i386.cpp (Browse further)
