ia64 build errors

Hi Tony,

I've kicked off IA64 build tests on a native IA64 box and the test
kconfigs are:

 ia64-allmodconfig
 ia64-allnoconfig
 ia64-defconfig
 ia64-randconfig-h001
 ...
 ia64-randconfig-h009

Only the allnoconfig and defconfig builds fine. The other ones mostly failed in two errors:

1)

                 from kernel/bounds.c:9:

2)

In file included from arch/ia64/kernel/asm-offsets.c:9:0:
include/linux/sched.h: In function 'stack_not_used':
include/linux/sched.h:2519:21: error: 'IA64_TASK_SIZE' undeclared (first use in this function)

include/linux/sched.h:2519:21: error: 'IA64_THREAD_INFO_SIZE' undeclared (first use in this function)

3) and one randconfig failed with lots of undefined symbols (attached).

Thanks,
Fengguang

These are all good. Thanks for adding to your testbuild farm.

ia64 hasn't seen any real effort to resolve problems that
show up in random configurations - so I'm not surprised
that you found some (I might be surprised that you
found so few!)

I'm not quite sure where to go with these reports though.
It looks like the first was from a CONFIG_PRINTK=n kernel.
This isn't ever going to be a useful option for ia64. I presume
it is there to shave down the size of the kernel by a few hundred
bytes on embedded systems ... but with systems starting at
32GB ... this is never going to be significant for ia64. Also mission
critical systems will always choose better diagnostics over
saving some small amount of memory.

So should I juggle header include lines to fix this non-problem?
Should I make it go away with a "select PRINTK" line in
arch/ia64/Kconfig?
Or just tell you that I'm not that into randconfig?

You are welcome!

I just added another alldefconfig and it works fine :)

Fair enough. My thought is there will be inevitably some initial
enabling pain for randconfig errors. However once done, the system
will be catching new errors which will most likely be introduced by
random community developers who will be notified to fix the error.
You may not even notice that things get broken and fixed again :)

Anyway, let's focus on the regular configs for now: when removing the
randconfig tests, only the IA64_TASK_SIZE error remains in allmodconfig.

Thanks,
Fengguang

Ok - I'll look into and fix that one (I feel especially motivated since I put in
the patch to drop variable  TASKSIZE recently ... so it's highly likely that this
break is my fault :-)
