RE: [Linux-ia64] Error compiling 2.4.20 for i386

["Bahnsen, Bruce" <bruce.bahnsen@intel.com>]

Thanks Bjorn

I was under the mistaken impression that the ia64 patch for 2.4.18 and
beyond would not break ia32. I am looking for a way to support both ia32 and
ia64 from a single kernel source. Is there a plan for the ia64 patch to
support this model?

The smp_threads_ready error is just gcc-3 being more picky about matching
volatile qualifiers. I can get ia64 to compile now. However, I'm getting
this link error now...

net/network.o(.debug_info+0x6f4b26): undefined reference to `L5661'

If you want an i386 kernel, there is no reason to use the ia64 patch.

I'll look at this for the 2.4.21 patch, but in general, I do not pay
any attention to the i386 kernel when producing the ia64 patch.

2.4.20 has very old ACPI bits in it, so the ia64 patch contains a
large ACPI update.  The ia64-specific ACPI bits match, of course,
but I don't bother to update the i386-specific ACPI bits.  So it's
likely that this is a result of that mismatch.

Hmm...  Obviously I don't see this error, but I'm using an old (2.96)
gcc.  Maybe newer ones are pickier.  In any case, I've removed
the "volatile" declaration of smp_threads_ready in smpboot.c, so
this won't be an issue for 2.4.21.
