Porting 32bit code to 64bit

[vikramaditya234]

I am working on a 64bit processor (Linux platform) and i have a small code which is not working on that processor, but works good on 32bit processor.

Code:
asm("movl $0x564D5868, %eax");
asm("movw $0x0A, %cx");
asm("movw $0x5658, %dx");
asm("inl %dx, %eax");

Please tell me how can make it work it on the 64bit processor.

Thanks
