[NTOS:EX/KE][HALX86] Add support for NUMPROC, BOOTPROC, MAXPROC, ONECPU boot switches ( #6024 )
...
These SMP-specific switches allow to test and control configurations
with various number of CPUs on multiprocessor systems.
- NUMPROC: maximum number of logical processors that can be started
(including dynamically, not currently supported by ReactOS) at run-time.
- BOOTPROC: maximum number of logical processors that can be started at
boot-time.
- MAXPROC: forces the OS to report the maximum possible number of CPUs
as existing on the system.
- ONECPU (MP HAL-only boot switch): causes the HAL to only use one
(the boot) CPU on a multiprocessor system. Attempting to start other
processors will fail.

[HALX86] acpi/madt.c: Rewrite it ( #6032 )
...
Especially HalpParseApicTables() which looked early-WIP and was buggy.
And keep smp/mps/mps.c in sync'.

[NTOS:KE][HALX86] Implement AP startup code ( #5879 )
...
Co-authored-by: Victor Perevertkin <victor.perevertkin@reactos.org >
Introduce the initial changes needed to get other processors up and into kernel mode.
This only supports x86 as of now but is the first real step towards using other system processors.
