Missing features 2-4 support in /proc/cpuinfo for AMD CPUs on i386

[Bernd Ernesti <netbsd%lists.veego.de@localhost>]

Hi,

it seems that /proc/cpuinfo is kind of broken because it doesn't show all
informations now (it used to provide more):

# cpuctl identify 0
cpu0: AMD Athlon X2 or Athlon 64 X2 (686-class), 2506.49 MHz, id 0x60fb2
cpu0: features 178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features 178bfbff<PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX>
cpu0: features 178bfbff<FXSR,SSE,SSE2,HTT>
cpu0: features2 2001<SSE3,CX16>
cpu0: features3 ebd3fbff<SCALL/RET,NOX,MXX,FFXSR,RDTSCP,LONG,3DNOW2,3DNOW>
cpu0: features4 11f<LAHF,CMPLEGACY,SVM,EAPIC,ALTMOVCR0,3DNOWPREFETCH>
cpu0: "AMD Athlon(tm) Dual Core Processor 4850e"

# cat /proc/cpuinfo
[..]
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov 
pat pse36 clflush mmx fxsr sse sse2 ht 


It seems that features 2-4 are no in the flags output and so programs like the
configure check in mplayer doesn't find all flags.
