I assume some hundred users (if not some thousand, as entries in bugreports are only the tip of an iceberg) are affected by this issue.

No, this is not an acceptable patch per se.

The right way to do this is to have the option, if it is found, simply
set the bit in the CPU array.  However, it is important to verify that
we are on the affected type of CPU, specifically the affected Pentium Ms.

x86 patches should be sent to <x86@...nel.org> or equivalently myself,
<mingo@...nel.org> and <tglx@...utronix.de> and Cc:
<linux-kernel@...r.kernel.org>.  I also encourage you to read the file
Documentation/SubmittingPatches before trying again.
