Linus,

The issue Sam refers to is that UTS_MACHINE is set to "x86" instead of
"i386" or "x86_64" when building with ARCH=x86. Thus the new kernel
when booted will give either "x86" on x86_64 and many i386 systems or
even "x66" on other i386 systems for 'uname -m'.

Many tools rely on the usual values of "x86_64", "i366" and "i686"
here. So we shouldn't change this.

Attached patch fixes that issue. Please apply.


Regards,

Andreas
