From 7c7a49958286fee9a2b18baffc9c626304a00843 Mon Sep 17 00:00:00 2001 From: James Morse Date: Fri, 7 Jun 2019 16:14:07 +0100 Subject: [PATCH] Documentation: x86: Remove cdpl2 unspported statement and fix capitalisation "L2 cache does not support code and data prioritization". This isn't true, elsewhere the document says it can be enabled with the cdpl2 mount option. While we're here, these sample strings have lower-case code/data, which isn't how the kernel exports them.
