From 79ba6ac825fac187894e236c9df1ba5fcbf53fd3 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sat, 4 Jul 2009 08:10:58 +0900 Subject: [PATCH] x86: make pcpu_chunk_addr_search() matching stricter The @addr passed into pcpu_chunk_addr_search() is unit0 based address and thus should be matched inside unit0 area. Currently, when it uses chunk size when determining whether the address falls in the first chunk. Addresses in unitN where N>0 shouldn't be passed in anyway, so this doesn't cause any malfunction but fix it for consistency.
