============
VM_DllSyscall
Dlls will call this directly
rcg010206 The horror; the horror.
The syscall mechanism relies on stack manipulation to get its args.
This is likely due to C's inability to pass "..." parameters to
a function in one clean chunk. On PowerPC Linux, these parameters
are not necessarily passed on the stack, so while (&arg[0] == arg)
is true, (&arg[1] == 2nd function parameter) is not necessarily
accurate, as arg's value might have been stored to the stack or
other piece of scratch memory to give it a valid address, but the
next parameter might still be sitting in a register.
Quake's syscall system also assumes that the stack grows downward,
and that any needed types can be squeezed, safely, into a signed int.
This hack below copies all needed values for an argument to a
array in memory, so that Quake can get the correct values. This can
also be used on systems where the stack grows upwards, as the
presumably standard and safe stdargs.h macros are used.
As for having enough space in a signed int for your datatypes, well,
it might be better to wait for DOOM 3 before you start porting. :)
The original code, while probably still inherently dangerous, seems
to work well enough for the platforms it already works on. Rather
than add the performance hit for those platforms, the original code
is still in use there.
For speed, we just grab 15 arguments, and don't worry about exactly
how many the syscall actually needs; the extra is thrown away.

*
* [47:40] - Low 8 bits of the page Node ID extracted from coretalk

* [39:38] - Chiplet ID extracted from coretalk address [39:38]
* [37:00] - node offset extracted from coretalk address [37:00]
*
* Since the node id in general will be non-zero, and the chiplet id
* will always be non-zero, it follows that the device must support
* a dma mask of at least 0xffffffffff (40 bits) to target node 0
* and in general should be 0xffffffffffff (48 bits) to target nodes
* up to 255. Nodes above 255 need the support of the xxx register,

* xxx - xxx+255.

*
* The OMAP2 processor can be run at several discrete 'PRCM configurations'.
* These configurations are characterized by voltage and speed for clocks.
* The device is only validated for certain combinations. One way to express
* these combinations is via the 'ratios' which the clocks operate with
* respect to each other. These ratio sets are for a given voltage/DPLL
* setting. All configurations can be described by a DPLL setting and a ratio.
*
* 2430 differs from 2420 in that there are no more phase synchronizers used.
* They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
* 2430 (iva2.1, NOdsp, mdm)
*
* XXX Missing voltage data.
* XXX Missing 19.2MHz sys_clk rate sets.
*
* THe format described in this file is deprecated. Once a reasonable
* OPP API exists, the data in this file should be converted to use it.
*
* This is technically part of the OMAP2xxx clock code.

**
** Description: Implementation of the standard library function memcpy.
** This implementation of memcpy() is ANSI-C89 compatible.
**
** The following configuration options can be set:
**
** CONFIG_CPU_LE - Uses processor with little endian
** addressing. Default is big endian.
** Note: This is defined by menuconfig
**
** PRE_INC_PTRS - Use pre increment of pointers.
** Default is post increment of
** pointers.
**
** INDEXED_COPY - Copying data using array indexing.
** Using this option, disables the
** PRE_INC_PTRS option.
**
** CONFIG_64BIT - Compiles memcpy for 64 bit
** architectures
** Note: This is defined by menuconfig
**
**
** Best Settings:
**
** Intel x86: CONFIG_CPU_LE and INDEXED_COPY
** ARM: TBD
** Other processors: TBD

/*
* ALI M14xx chipset EIDE controller
*
* Works for ALI M1439/1443/1445/1487/1489 chipsets.
*
* Adapted from code developed by derekn@vw.ece.cmu.edu. -ml
* Derek's notes follow:
*
* I think the code should be pretty understandable,
* but I'll be happy to (try to) answer questions.
*
* The critical part is in the setupDrive function. The initRegisters
* function doesn't seem to be necessary, but the DOS driver does it, so
* I threw it in.
*
* I've only tested this on my system, which only has one disk. I posted
* it to comp.sys.linux.hardware, so maybe some other people will try it
* out.
*
* Derek Noonburg (derekn@ece.cmu.edu)
* 95-sep-26
*
* Update 96-jul-13:
*
* I've since upgraded to two disks and a CD-ROM, with no trouble, and
* I've also heard from several others who have used it successfully.
* This driver appears to work with both the 1443/1445 and the 1487/1489
* chipsets. I've added support for PIO mode 4 for the 1487. This
* seems to work just fine on the 1443 also, although I'm not sure it's
* advertised as supporting mode 4. (I've been running a WDC AC21200 in
* mode 4 for a while now with no trouble.) -Derek
