Log:
New i386 SMP code:
- The MP code no longer knows anything specific about an MP Table.
Instead, the local APIC code adds CPUs via the cpu_add() function when
a local APIC is enumerated by an APIC enumerator.
- Don't divide the argument to mp_bootaddress() by 1024 just so that we
can turn around and mulitply it by 1024 again.
- We no longer panic if SMP is enabled but we are booted on a UP machine.
- init_secondary(), the asm code between init_secondary() and ap_init()
in mpboot.s and ap_init() have all been merged together in C into
init_secondary().
- We now use the cpuid feature bits to determine if we should enable
PSE, PGE, or VME on each AP.
- Due to the change in the implementation of critical sections, acquire
the SMP TLB mutex around a slightly larger chunk of code for TLB
shootdowns.
- Remove some of the debug code from the original SMP implementation
that is no longer used or no longer applies to the new APIC code.
- Use a temporary hack to disable the ACPI module until the SMP code has
been further reorganized to allow ACPI to work as a module again.
- Add a DDB command to dump the interesting contents of the IDT.
