Improved page fault scalability for HugeTLB
The updated Linux kernel has improved page fault scalability for HugeTLB. Previously only one HugeTLB page fault could be processed at a time because a single mutex was used. The improved method uses a table of mutexes, allowing for page faults to be processed in parallel. Calculation of the mutex table includes the number of page faults occurring and memory in use.
kdump supports hugepage filtering
To reduce both vmcore size and capture run time, kdump now treats hugepages as userpages and can filter them out. As hugepages are primarily used for application data, they are unlikely to be relevant in the event a vmcore analysis is required.
Support for 802.1X EAP packet forwarding on bridges
Bridge forwarding of 802.1x EAP packets is now supported, allowing for selective forwarding of some non-control link-local packets. This change also enables the use of 802.1X to authenticate a guest on a RHEL6 hypervisor using Linux bridge on a switch port.
Rebase of the mtip32xx driver
The Red Hat Enterprise Linux 6.7 kernel includes the most recent upstream version of the mtip32xx device driver. This version adds support for Micron SSD devices.
