cache size misdetected with 2.4.20 + P3m

cache size misdetected with 2.4.20 + P3m

[Martin Pirker]

Hi...

just did an update from 2.4.17 to 2.4.20 + cpufreq 2.4.20-rc3-1

2.4.17:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 11
model name      : Intel(R) Pentium(R) III Mobile CPU       933MHz
stepping        : 1
cpu MHz         : 930.254
cache size      : 512 KB
....

2.4.20:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 11
model name      : Intel(R) Pentium(R) III Mobile CPU       933MHz
stepping        : 1
cpu MHz         : 930.255
cache size      : 32 KB


chipset (if that matters): 830M
tried with cpufreq enabled and without

Question: Where has the cache gone? Is this just wrong in /proc/cpuinfo
or are really just 32KB used? (and how to test this?)

PS: cpufreq is very useful :)
