[PATCH v1 0/4] Get writable masks for feature ID from userspace

[Jing Zhang]

This patch series were part of [1], but actually are independent from that.
In this patch series, a VM ioctl is added to allow userspace to get writable
masks for feature ID registers.
Another two fixes for ID registers are also included in this series.
This is based on v6.6-rc2.
