This patch contain the following linux kernel features:

Summary:

kernel (new function): Collaborative Memory Management Stage II.

Description:

Support for the Collaborative Memory Management Assist (CMMA) in z/VM 5.3 reduces hypervisor paging I/O overhead. See 'Improved memory management for Linux guests' in IBM U.S. Software Announcement Letter 207-019 "IBM z/VM V5.3 - Improving scalability, security, and virtualization technology IBM". The Linux support for CMM2 is activated per IPL-option cmma=on (default is cmma=off). This patch replaces the 2006-11-17 optional recommended "cmm2" kernel 2.6.16 add-on.

Summary:	kernel (new function): Data execution protection for user processes.
Description:	This feature provides an execution protection for code in user space data segments which are marked as not executable. It can prevent, for example, stack overflow exploits and generally makes a system insensitive to buffer-overflow attacks in user space. This patch replaces the 2006-11-17 optional recommended "Data execution protection" kernel 2.6.16 add-on.
