This removes the limit on the number of cpus we can boot.

Local APIC ID is different on x2apic, so we need a virtual function.

Used to initialize the APIC on non-boot processors.

for use in special cases only; normal threaded use should prefer mutex.

  bench: add context switch benchmark
  runtime: implement __cxa_guard_acquire()
  math: implement __isnan()
  mmu: implement page protection

While it works, it needs to move to the virtio layer

This isn't the right discovery mechnism and this should be simplified later on

osv:
     147 NanoTime
     574 context switch

fedora:
     322 NanoTime
    2484 context switch

(nanoseconds, on kvm, on my laptop)

Otherwise, static constructors in functions are never called.  This
manifested itself in the jit generating wrong code when compiling a function,
as the register calling convention was not initialized, and the jvm tried
to load all method arguments into %rax.

Not 100% it is right wrt SNaN, but it will fault if incorrect.

This allows us to use threads early on.

We want to initialize the scheduler before the filesystem, so we can't
depend on elf::program.

This avoids using separate protocols for setup and runtime.

several instances

It was trapped when I run qemu w/ additional virtio-blk device.
It seems that multiple drivers of the same instance aren't working well

afterwards issue a matching number of read request to verify the content.

While doing it fix an off by 1 of i

Still with minimal stack, no interrupt support, etc.

Now basic data exchange seems to work (w/o interrupts yet)
