f6da06b117 Work around the halt/wakeup race in barrier_halt_wait() (issue #13) 
There is an unavoidable race between one core halting after decrementing
the barrier count and another core sending it the wakeup NMI. This can
only occur if the core sending the wakeup is running at many times the
speed of the core halting, but it has been observed on an Intel Icelake
mobile processor.

ed0fd7830f Use IP instead of PC in interrupt display. 
It's better to use the x86 terminology here.

4078b7760e Faster barrier implementation. 
The old barrier implementation was very slow when running on a multi-socket
machine (pcmemtest issue 16).

The new implementation provides two options:

  - when blocked, spin on a thread-local flag
  - when blocked, execute a HLT instruction and wait for a NMI

The first option might be faster, but we need to measure it to find out. A
new boot command line option is provided to select between the two, with a
third setting that uses a mixture of the two.

06d670e9a8 Make sure the boot command line is accessible during startup. 
If we remap other regions, it's possible it could get overlaid.

e99a7aedb3 Revert to starting APs before doing the dummy runs. 
That optimisation occasionally caused a hang if the CPU sequencing
mode was reconfigured after testing had started. It didn't make a
significant difference to the startup delay, so just drop it.

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.

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.

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.
