some still useful bits of the reverted revision. The problem with the committed fix is that there are still issues with returning from NMI, when NMI interrupted kernel in a moment where the kernel segments selectors were still not loaded into registers. If this happens, the NMI return would loose the userspace selectors because r323722 does not reload segment registers on return to kernel mode. Fixing the problem is complicated. Since an alternative approach to handle the original bug exists, it makes sence to stop adding more complexity. Discussed with: bde Sponsored by: The FreeBSD Foundation MFC after: 1 week |
