62c666566e SMP - We boot APs
- kernel detects CPUs by searching ACPI tables for local apic nodes

- each CPU has its own TSS that points to its own stack. All cpus boot
  on the same boot stack (in sequence) but switch to its private stack
  as soon as they can.

- final booting code in main() placed in bsp_finish_booting() which is
  executed only after the BSP switches to its final stack

- apic functions to send startup interrupts

- assembler functions to handle CPU features not needed for single cpu
  mode like memory barries, HT detection etc.

- new files kernel/smp.[ch], kernel/arch/i386/arch_smp.c and
  kernel/arch/i386/include/arch_smp.h

- 16-bit trampoline code for the APs. It is executed by each AP after
  receiving startup IPIs it brings up the CPUs to 32bit mode and let
  them spin in an infinite loop so they don't do any damage.

- implementation of kernel spinlock

- CONFIG_SMP and CONFIG_MAX_CPUS set by the build system

b7eb096088 Makefiles: remove -D__minix for assembly invocations.
They seem to be redundant (for gcc+ack+clang) and produce
very messy warnings (for clang, due to it already being defined).

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

0f4eda33eb new base libaudiodriver out of -lcommon in drivers/audio.
- this lets the drivers that used that library be compiled easily with
   different compilers.

4b9420d7d7 mk: use ar instead of gar for gcc/clang ar. 2010-08-18 16:08:10 +00:00

a46b8b84d4 aal - don't install yourself as ar; must invoke aal explicitly for ack archives.
To make switching to 'ar' for gcc/clang archives smoother in the future.
