The patch adds one more option (EEH_OPT_FREEZE_PE) to set_option()
method to proactively freeze PE, which will be issued before resetting
pass-throughed PE to drop MMIO access during reset because it's
always contributing to recursive EEH error.

The series of patches is to fix recursive EEH error during recovery
for VFIO-PCI except some cleanup. The recursive EEH error is caused
by MMIO access when the PE is under reset or the PCI device isn't
enabled yet. The solution is to freeze the PE until the PCI device
is enabled after PE reset.

MADV_FREE needs pmd_dirty and pmd_mkclean for detecting recent
overwrite of the contents since MADV_FREE syscall is called for
THP page.
This patch adds pmd_dirty and pmd_mkclean for THP page MADV_FREE
support.
