Hello List,

I just noticed this:

devilkin@precious:~$ cat /proc/cpuinfo 
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 9
model name      : Intel(R) Pentium(R) M processor 1600MHz
stepping        : 5
cpu MHz         : 599.511
cache size      : 0 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe tm2 est
bogomips        : 1196.85

Somehow, the cache size doesn't seem to be correct. Spec info tells me that this cpu
has indeed a 1024kb cache.

Any patches to test?

Thankx

Jan

This works like a charm. Thanks. Maybe for inclusion in 2.4.23-pre6?

Marcelo, can this be included in 2.4.23-pre6? It fixed the 0 KB L2 cache for 
Pentium M cpu's.
