2440ffae49 Kernel exports DSDP and apic_enabled in machine structure 
- kernel exports DSDP (the root pointer where ACPI parsing starts) and
  apic_enabled in the machine structure.

- ACPI driver uses DSDP to locate ACPI in memory. acpi_enabled tell
  PCI driver to query ACPI for IRQ routing information.

344e9221ec Kernel supports up to 64 IRQs 
- enough for 2 io apics (usually with 24 pins)

45badf4c05 ACPI in kernel 
- the ability for kernel to use ACPI tables to detect IO APICs. It is
  the bare minimum the kernel needs to know about ACPI tables.

- it will be used to find out about processors as the MPS tables are
  deprecated by ACPI and not all vendorsprovide them.

b3c3a1cb1e gcc compiles - add -fno-builtin so that gcc optimisations don't break things. 
- kernel compile was broken with gcc as putchar() was added by gcc in
    stacktrace.c
  - add -fno-builtin everywhere to avoid such problems in the future
  - -fno-builtin in kernel now redundant

76708e9bf4 mini_receive() clean up 
- for better readability xpp is substitued by sender

- makes sure that the dequeued sender has p_q_link == NULL and that
  this condition holds when enqueuing the sender again. This is a
  sanity check to make sure that the new sender is not enqueued
  already

- Before this change the dequeued sender's p_q_link may not be NULL
  and it was only set to NULL when enqueued again

360de619c0 No linear addresses in message delivery 
- removes p_delivermsg_lin item from the process structure and code
  related to it

- as the send part, the receive does not need to use the
  PHYS_COPY_CATCH() and umap_local() couple.  

- The address space of the target process is installed before
  delivermsg() is called.

- unlike the linear address, the virtual address does not change when
  paging is turned on nor after fork().
