Thank you for correction again.
At this time, I've download the source from
BK:/linux.bkbits.net:8080/linux-2.6 and found that the source already
includes 'compat_ioctl' support. Here, I'm sending another patch that has
fix for this issue.
I've verified (also, recreated above error with previous patch) this by
applying the patch to the source from BK.
I'm learning from your great comments and I appreciate your time on this.
Please let me know for any comment.

Thank you.

+Release Date : Mon Mar 07 12:27:22 EST 2005 - Seokmann Ju <sju@xxxxxxxx>
+Current Version : 2.20.4.6 (scsi module), 2.20.2.6 (cmm module)
+Older Version : 2.20.4.5 (scsi module), 2.20.2.5 (cmm module)
+
+1. Added IOCTL backward compatibility.
+ Convert megaraid_mm driver to new compat_ioctl entry points.
+ I don't have easy access to hardware, so only compile tested.
+ - Signed-off-by:Andi Kleen <ak@xxxxxx>
+
+2. megaraid_mbox fix: wrong order of arguments in memset()
+ That, BTW, shows why cross-builds are useful-the only indication of
+ problem had been a new warning showing up in sparse output on alpha
+ build (number of exceeding 256 got truncated).
+ - Signed-off-by: Al Viro
+ <viro@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>
+
+3. Convert pci_module_init to pci_register_driver
+ Convert from pci_module_init to pci_register_driver
+ (from:http://kerneljanitors.org/TODO)
+ - Signed-off-by: Domen Puncer <domen@xxxxxxxxxxxx>
+
+4. Use the pre defined DMA mask constants from dma-mapping.h
+ Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when
calling
+ pci_set_dma_mask() or pci_set_consistend_dma_mask(). See
+ http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for more
+ details.
+ Signed-off-by: Tobias Klauser <tklauser@xxxxxxxxxxx>
+ Signed-off-by: Domen Puncer <domen@xxxxxxxxxxxx>
+
+5. Remove SSID checking for Dobson, Lindsay, and Verde based products.
+ Checking the SSVID/SSID for controllers which have Dobson, Lindsay,
+ and Verde is unnecessary because device ID has been assigned by LSI
+ and it is unique value. So, all controllers with these IOPs have to
be
+ supported by the driver regardless SSVID/SSID.
+
+6. Date Thu, 27 Jan 2005 04:31:09 +0100
+ From Herbert Poetzl <>
+ Subject RFC: assert_spin_locked() for 2.6
+
+ Greetings!
+
+ overcautious programming will kill your kernel ;)
+ ever thought about checking a spin_lock or even
+ asserting that it must be held (maybe just for
+ spinlock debugging?) ...
+
+ there are several checks present in the kernel
+ where somebody does a variation on the following:
+
+ BUG_ON(!spin_is_locked(&some_lock));
+
+ so what's wrong about that? nothing, unless you
+ compile the code with CONFIG_DEBUG_SPINLOCK but
+ without CONFIG_SMP ... in which case the BUG()
+ will kill your kernel ...
+
+ maybe it's not advised to make such assertions,
+ but here is a solution which works for me ...
+ (compile tested for sh, x86_64 and x86, boot/run
+ tested for x86 only)
+
+ best,
+ Herbert
