Thanks again for the review.
I have sent patch v6 addressing your consolidated feedback except a couple
of things that you suggested.
I guess DEFINE_DEBUGFS_ATTRIBUTE is linux-next so to avoid possible build
issues can we skip this for now? We can revisit this change when this is
readily available in the mainline kernel in near future.
Also, Makefile and Kconfig files in pdx86 need alphabetical sorting so
skipped the suggestion related to alphabetical placement in Makefile.
