Chuck Ebbert ff347b2215 [PATCH] x86-64: Fix incorrect FP signals 
This is the same patch that went into i386 just before 2.6.13
came out.  I still can't build 64-bit user apps, so I tested
with program (see below) in 32-bit mode on 64-bit kernel:

Before:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown]
	handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
	handler: i387 unmasked precision exception, rounded up

After:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result]
	handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
	handler: i387 unmasked precision exception, rounded up
