Fixes/Additions from the upstream distribution provider

     * A new tunable parameter /proc/sys/vm/max_writeback_pages  has been added
       to the kernel, allowing system administrators to change the maximum 
       number of modified pages kupdate writes to disk per iteration each time 
       it runs. It defaults to 1024 or 4MB so that a maximum of 1024 pages get 
       written out by each iteration of kupdate.
     * A new option (CONFIG_TASK_IO_ACCOUNTING=y) has been added to kernel to 
       assist in monitoring IO statistics per process.
     * The rd_blocksize option in  kernel's ramdisk driver is removed.
     * This release adds the kernel version details to oops and panic output.
     * The serial_reg.h file is included in the kernel_headers rpm.
     * Functionality has been added to sysrq-t to display backtrace information 
       about running processes.
     * This update increases the maximum length of the kernel key field from the
       arbitrary 32 character length set in previous kernels to 255 characters.
     * This  update addresses the security concern arising from non-root users 
       being able to create device nodes on filesystems exported using NFSD 
       (Network File System daemon).
     * Added code to produce a signature file that GRUB performs a checksum 
       against during the boot process.
     * Added code to change the DSA key from 512 bit to 1024 bit for module 
       signing.
     * Asymmetric Logical Unit Access (ALUA) support in device-mapper-multipath
       has been updated, adding explicit ALUA support for Clariion storage.
     * Added support for raw devices. the initscripts packages is  updated to 
       add  functionality of raw devices.
     * The -fwrapv variable added to GCC CFLAGS in order to define wrapping 
       behavior.
