efc9a9c16a Don't attempt to start the APs when restarting after a config change. 
Leave the APs running whilst the BSP repeats the dummy runs. This means
we need to bypass the barriers during a dummy run. The APs will wait at
the first barrier until the BSP starts the first real run.

2bf1623733 Halt CPU cores that are not active in a test. 
This saves a lot of power when performing sequential tests.

39d5715224 Fix interrupt handling when long mode is enabled in a 32-bit binary (part 2). 
Handle passing the processor state to the application interrupt handler.
Update the 64-bit code to match the new trap state structure definition.

dcac527068 Don't make assumptions about usable memory. 
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.

There are still some assumptions in the USB driver code that need to
be fixed.

fb0f1a7fe5 Don't start APs until after dummy runs have finished. 
This should significantly improve startup time on machines with many
cores, as the barriers become no-ops during the dummy runs.

ccab9ab081 Fix operation with a subset of CPU cores enabled. 
The last commit removed too much - there are a couple of places where
we need to use a virtual CPU number rather than a physical CPU number.

16d55b7dad Remove distinction between physical and virtual CPUs. 
This is no longer needed, now we can display as many CPUs as we can
physically handle.

4100a44b12 Properly protect the startup stack with a mutex. 
Because we start the APs sequentially, it is unlikely they will coincide
for the brief period that they use the temporary startup stack, but we
should guard against it. This allows us to remove the mutex around the
restart of each AP when relocating, which should improve test times.

151870cc0b Display enabled CPUs as a scrollable list in the config menu. 
This removes a constraint on the number of CPU cores we can support.

09890bf0cd Support more than 32 CPU cores in main display. 
Either one core is active or all enabled cores are active, so we don't
really need a separate spinner for each core.
