Peter Anvin CommitDate: Mon, 23 Nov 2009 17:09:59 -0800 x86, platform: Change is_untracked_pat_range() to bool; cleanup init - Change is_untracked_pat_range() to return bool. - Clean up the initialization of is_untracked_pat_range() -- by default, we simply point it at is_ISA_range() directly. - Move is_untracked_pat_range to the end of struct x86_platform, since it is the newest field.
