From ff891875c1a079c55cb5def525c2448c4cbed98c Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 13 Feb 2018 13:22:08 -0600 Subject: x86/cpu: Change type of x86_cache_size variable to unsigned int commit 24dbc6000f4b9b0ef5a9daecb161f1907733765a upstream. Currently, x86_cache_size is of type int, which makes no sense as we will never have a valid cache size equal or less than 0. So instead of initializing this variable to -1, it can perfectly be initialized to 0 and use it as an unsigned variable instead. Suggested-by: Thomas Gleixner Signed-off-by: Gustavo A. R.
