-Subject: [PATCH 10/12] 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.
