Subject: x86, mm: Call is_untracked_pat_range() rather than is_ISA_range()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=55a6ca25472ee01574bfc24d23b7f5fa09cc38cf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86, mm: Call is_untracked_pat_range() rather than is_ISA_range()

Checkin fd12a0d69aee6d90fa9b9890db24368a897f8423 made the PAT
untracked range a platform configurable, but missed on occurrence of
is_ISA_range() which still refers to PAT-untracked memory, and
therefore should be using the configurable.
