Subject: Revert "Documentation/features/vm: Remove arch support status file for 'pte_special'"
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c7c527dd6e7687a2479c8508eda6e4b19fc6aebb;p=linux.git

Revert "Documentation/features/vm: Remove arch support status file for 'pte_special'"

The removal of this file appears to have been premature; it's not a feature
enabled by Kconfig, but it's a arch-level feature regardless.  Put it back
for now until some happy future time when we decide how we really want to
document such features.

This reverts commit 2bef69a385b4c1c01d8abae0aa035f0ffa051f07.
