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)

2)

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

Thanks,

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.

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 :-)
