Added support for correct locking of all LDT operations. Added separate functions to manipulate the %fs selector, which allows using a global GDT selector on recent Linux kernels.

/* NOTE: Interrupts might get called from four modes: real mode, 16-bit,

|
|
* For automatic conversion of pointer
|
|
* parameters, interrupt handlers should use CTX_SEG_OFF_TO_LIN with
|
|
* the contents of a segment register as second and the contents of
|
|
* a *32-bit* general register as third parameter, e.g.
|
|
* CTX_SEG_OFF_TO_LIN( context, DS_reg(context), EDX_reg(context) )

|
* This will generate a linear pointer in all three cases:
|
|
* Real-Mode: Seg*16 + LOWORD(Offset)
|
|
* 16-bit: convert (Seg, LOWORD(Offset)) to linear
|
|
* 32-bit segmented: convert (Seg, Offset) to linear
|
|
* 32-bit linear: use Offset as linear address (DeviceIoControl!)
|
|
*
|
|
* Real-mode is recognized by checking the V86 bit in the flags register,
|
|
* 32-bit linear mode is recognized by checking whether 'seg' is
|
|
* a system selector (0 counts also as 32-bit segment) and 32-bit
|
|
* segmented mode is recognized by checking whether 'seg' is 32-bit
|
|
* selector which is neither system selector nor zero.
