Ahmed Arif 229f7891a1 [FREELDR][HAL] Skip x86 BIOS emulator on UEFI boots (#8827)
Skip x86 BIOS emulator initialization on EFI boots by having FreeLdr populate EFI boot state in the loader block and making HAL consume it.

This keeps BIOS behavior unchanged while avoiding legacy BIOS/INT10 setup in the EFI path and preventing early EFI boot failures caused by entering the BIOS emulator path at all.

Hermès Bélusca-Maïto 3022d74beb [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.

Timo Kreuzer 10bb50b456 [HAL] Fix SMP initialization
- Don't use CONFIG_SMP, this isn't handled in (most of) hal
- Add a dummy HalpSetupProcessorsTable for UP
- Call HalpRegisterKdSupportFunctions only for processor 0

Adam Słaboń ce2d4740a6 [SDK][HAL] Enable x86Bios on x86 (#5454)
This will be needed for compatibility with x86 Windows Vista/7 videoprt.sys builds.
Might be also useful in future for platforms (x86 , ...) where V86 mode is not available or buggy.

Timo Kreuzer c5a700fd06 [HAL:X64] Fix/improve the BIOS interface
* Call HalInitializeBios both in phase 0 and 1
* In phase 0 allocate some physical memory, instead of using arbitrary hardcoded pages, that then end up as page tables and get filled with VESA tables

Victor Perevertkin 5c7ce4475e [REACTOS] Cleanup INIT and some PAGE section allocations
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore

Timo Kreuzer 71fefa32db [NDK][NTOS] Add global definition of INIT_FUNCTION/INIT_SECTION (#779)
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
