Tee-Kiah Chia 0114ab3be4 int2f: fix call interface around int2F_12_handler( )
This changes the interface between reloc_call_int2f_handler
(int2f.asm) and int2F_12_handler( ) (inthndlr.c) so that

  - int2F_12_handler( ) will not try to output values to its
    caller by passing "back" input parameter values
  - reloc_call_int2f_handler will switch to an internal
    stack before calling int2F_12_handler( ), so that SS ==
    DGROUP as expected by the latter.

This partly addresses https://github.com/FDOS/kernel/issues/11 .

(The call to syscall_MUX14( ) in int2f.asm seems to have
similar issues, and should probably also be updated.)

fd kernel

FreeDOS kernel - branch from 2042 SVN 0xFD kernel

http://www.fdos.org/kernel/

The FreeDOS kernel implements the core MS/PC-DOS (R) compatible functions. It is derived from Pat Villani's DOS-C kernel and released under the GPL v2. Please see http://www.freedos.org/ for more details about the FreeDOS (TM) Project. Compiled kernels ready to use (just copy kernel.sys over an existing install) are available at http://www.fdos.org/kernel/testing/git/ - also available are the source archive and fdpkg compatible packages.

This version of the kernel is intended only for 8086+ or 80386+ IBM compatible computers in continuation of the goals of the FreeDOS Project. Please see http://www.fdos.org/kernel for my 0xDC kernel that is work on merging back in some of the original portability aspects and other supported features at the cost of some compatibility with older hardware/software.

Please feel free to email me - PerditionC@gmail.com 2020

Build Status Now with automatic builds and soon tests on Travis CI
