From b6ff32d9aaeeeecf98f9a852d715569183585312 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Thu, 9 Apr 2009 14:26:51 -0700 Subject: x86, PAT: Consolidate code in pat_x_mtrr_type() and reserve_memtype() Fix pat_x_mtrr_type() to use UC_MINUS when the mtrr type return UC. This is to be consistent with ioremap() and ioremap_nocache() which uses UC_MINUS. Consolidate the code such that reserve_memtype() also uses pat_x_mtrr_type() when the caller doesn't specify any special attribute (non WB attribute).
