b178089251 Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process.
We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.

6d2734a074 Kernel/Memory: Give each Process its own page table.
The loader is in charge of setting the newly created process's page table as the main one during the loading process.

Kernel/HLE: Use a mutex  to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).

bca8916cea Kernel/HLE: Use a mutex to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).
This mutex is acquired in SVC::CallSVC, ie, as soon as the guest application enters the HLE kernel, and should be acquired by the aforementioned threads before modifying kernel structures.

fa228ca637 Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.
This is necessary for loading multiple processes at the same time.
The main thread will be automatically scheduled when necessary once the scheduler runs.

84c497292a Service: Add new ServiceFramework framework for writing HLE services
The old "Interface" class had a few problems such as using free
functions (Which didn't allow you to write the service handler as if it
were a regular class.) which weren't very extensible. (Only received one
parameter with a pointer to the Interface object.)

The new ServiceFramework aims to solve these problems by working with
member functions and passing a generic context struct as parameter. This
struct can be extended in the future without having to update all
existing service implementations.

6354d08359 Kernel: Add a dedicated SetHleHandler method to ServerPort/ServerSession
This allows attaching a HLE handle to a ServerPort at any point after it
is created, allowing port/session creation to be generic between HLE and
regular services.

e626a520ca HLE: Move SessionRequestHandler from Service:: to Kernel::
Most of the code that works with this is or will be in the kernel, so
it's a more appropriate place for it to be.

f18d454eb6 Kernel: Map special regions according to ExHeader
This replaces the hardcoded VRAM/DSP mappings with ones made based on
the ExHeader ARM11 Kernel caps list. While this has no visible effect
for most applications (since they use a standard set of mappings) it
does improve support for system modules and n3DS exclusives.
