Subject: x86: Remove CPU cache size output for non-Intel too
|
|
References: bnc#564618, FATE#306952
|
|
Patch-mainline: 2.6.33-rc1
|
|
Git-commit: b01c845f0f2e3f9e54e6a78d5d56895f5b95e818
|
|
|
|
As Dave Jones said about the output in intel_cacheinfo.c: "They
|
|
aren't useful, and pollute the dmesg output a lot (especially on
|
|
machines with many cores). Also the same information can be
|
|
trivially found out from userspace."
|
|
|
|
Give the generic display_cacheinfo() function the same treatment.
