- make Pentium IV and other post-P6 processors use the "i686" family name (same fix as the system_utsname.machine init fix which went into include/asm-i386/bugs.h in test10-pre4)

We should never have used anything but "i386" as the utsname... sigh.

Its questionable if we should include the 'i'

heh, agreed. let's rename 'em all x86 and be done with it. ;-)

True enough, personally I prefer "x86".

ia32 is the official name. OTOH, i[3-6]86 _are_ different beasts...

IA32 is a retcon, and is used only by Intel anyway. There are differences between the i686 lines that are significantly bigger than between the i486 and i586, and that doesn't even begin to count non-Intel chips.

However, changing it to "i386" consistently would still work with existing software. Using "x86" or "ia32" or "ix86pc" (what Solaris calls it) would break stuff.

ia32 is an intel trademark. Using it for non intel products is probably an actionable matter ..

Yet another reason to ignore it.

Speaking of using it for non-Intel products, this is a line from Documentation/Changes in Linux 2.4.0-test10-pre6:

Linux on IA-32 has recently switched from using as86 to using gas for

Should we change that to x86 or something?

Since Linux generally calls this i386 throughout, I would stick with calling it i386.
