This particular define should be fixed in the version that I commited.
I also put dummy asm/fptest.h for all other architectures than x86, I
would now need volunteers with other hardware than x86 to implement
asm/fptest.h for their platform and run the test.

A little explanation of what work should be done: two functions
fp_regs_set and fp_regs_check should be implemented. fp_regs_set should
set all fp registers to the integer value passed as
argument. fp_regs_check should check that all fp registers are set to
the integer value passed as argument, print the incorrect registers if
any and return 1 if some register value is incorrect.

IMO setting every reg to a different value would be better, or like I did, calculate some value using every reg and only check the final result. That would also make pointer (to the fpu save area) corruptions/miscalculations and interruptions to the fpu save/restore routines better visible.
