Analyze and fix the following issue in the Linux kernel code: [PATCH] x86: AUX_DEVICE_INFO is one byte long, use 'movb'
Problem Details: Bugzilla #6552 says: "In arch/i386/boot/setup.S, movw is used instead of movb for PS/2 mouse information, although it is unsigned char.

Problem Details: Unfortunately, sparc64 doesn't have an easy way to do a "64 X 64 --> 128" bit multiply like PowerPC and IA64 do. We were doing a "64 X 64 --> 64" bit multiple which causes overflow very quickly with a 30-bit quotient shift. So use a quotientshift count of 10 instead of 30, just like x86 and ARM do. ...
