to represent the cpuset hierarchy provides for a familiar permission
and name space for cpusets, with a minimum of additional kernel code.
The cpus file in the root (top_cpuset) cpuset is read-only.
It automatically tracks the value of cpu_online_map, using a CPU
hotplug notifier. If and when memory nodes can be hotplugged,
we expect to make the mems file in the root cpuset read-only
as well, and have it track the value of node_online_map.

Release Date : Fri May 19 09:31:45 EST 2006 - Seokmann Ju <sju@lsil.com>
Current Version : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module)
Older Version : 2.20.4.8 (scsi module), 2.20.2.6 (cmm module)
1. Fixed a bug in megaraid_init_mbox().
Customer reported "garbage in file on x86_64 platform".
Root Cause: the driver registered controllers as 64-bit DMA capable
for those which are not support it.
Fix: Made change in the function inserting identification machanism
identifying 64-bit DMA capable controllers.

2. When INQUIRY with EVPD bit set issued to the MegaRAID controller,
system memory gets corrupted.
Root Cause: MegaRAID F/W handle the INQUIRY with EVPD bit set
incorrectly.
Fix: MegaRAID F/W has fixed the problem and being process of release,
soon. Meanwhile, driver will filter out the request.
3. One of member in the data structure of the driver leads unaligne
issue on 64-bit platform.
Customer reporeted "kernel unaligned access addrss" issue when
application communicates with MegaRAID HBA driver.
Root Cause: in uioc_t structure, one of member had misaligned and it
led system to display the error message.
Fix: A patch submitted to community from following folk.
