Venki Pallipadi 77db988564 x86/PCI: X86_PAT & mprotect ... Some versions of X used the mprotect workaround to change caching type from UC to WB, so that it can then use mtrr to program WC for that region [1]. Change the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS. With this change, X will not need to use mprotect workaround to get WC type since the MTRR mapping type will be honored. The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So, this X workaround will stop working as well.
