[PATCH] cpuid x87 bit on AMD falsely marked as PNI

http://bugme.osdl.org/show_bug.cgi?id=4426

vendor_id       : AuthenticAMD
cpu family      : 6
model           : 10
model name      : AMD Athlon(tm) XP
stepping        : 0
cpu MHz         : 2204.807
<snipped>
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 mmx fxsr sse pni syscall mmxext 3dnowext 3dnow
bogomips        : 4358.14

We're marking bit 0 of extended function 0x80000001 cpuid as PNI support on
AMD processors, when it actually denotes x87 FPU present.  Patch for i386
and x86_64 below.
