* If this is the first time we are called for this process,
* hack the memory image of WIN32S16 so that it doesn't try
* to access the GDT directly ...
*
* The first code segment of WIN32S16 (version 1.30) contains
* an unexported function somewhere between the exported functions
* SetFS and StackLinearToSegmented that tries to find a selector
* in the LDT that maps to the memory image of the LDT itself.
* If it succeeds, it stores this selector into a global variable
* which will be used to speed up execution by using this selector
* to modify the LDT directly instead of using the DPMI calls.
*
* To perform this search of the LDT, this function uses the
* sgdt and sldt instructions to find the linear address of
* the (GDT and then) LDT. While those instructions themselves
* execute without problem, the linear address that sgdt returns
* points (at least under Linux) to the kernel address space, so
* that any subsequent access leads to a segfault.
*
* Fortunately, WIN32S16 still contains as a fallback option the
* mechanism of using DPMI calls to modify LDT selectors instead
* of direct writes to the LDT. Thus we can circumvent the problem
* by simply replacing the first byte of the offending function
* with an 'retf' instruction. This means that the global variable
* supposed to contain the LDT alias selector will remain zero,
* and hence WIN32S16 will fall back to using DPMI calls.
*
* The heuristic we employ to _find_ that function is as follows:
* We search between the addresses of the exported symbols SetFS
* and StackLinearToSegmented for the byte sequence '0F 01 04'
* (this is the opcode of 'sgdt [si]'). We then search backwards
* from this address for the last occurrence of 'CB' (retf) that marks
* the end of the preceeding function. The following byte (which
* should now be the first byte of the function we are looking for)
* will be replaced by 'CB' (retf).
*
* This heuristic works for the retail as well as the debug version
* of Win32s version 1.30. For versions earlier than that this
* hack should not be necessary at all, since the whole mechanism
* ('PERF130') was introduced only in 1.30 to improve the overall
* performance of Win32s.
