When CONFIG_PRINTK is not set, the CMPXCHG_BUGCHECK() macro calls
_printk(), but _printk() is a static inline function, not available
as an extern.
Since the purpose of the macro is to print the BUGCHECK info,
make this config option depend on PRINTK.
Fixes multiple occurrences of this build error:
../include/linux/printk.h:208:5: error: static declaration of '_printk' follows non-static declaration
208 | int _printk(const char *s, ...)
| ^~~~~~~
In file included from ../arch/ia64/include/asm/cmpxchg.h:5,
../arch/ia64/include/uapi/asm/cmpxchg.h:146:28: note: previous declaration of '_printk' with type 'int(const char *, ...)'
146 | extern int _printk(const char *fmt, ...);
Fixes: 85f8f7759e41 ("ia64: populate the cmpxchg header with appropriate code")

Selecting this option turns on bug checking for the IA-64
compare-and-exchange instructions. This is slow! Itaniums

I don't think this fixes tag makes sense either as it was just a
straightforward code relocation. As pointed out elsewhere, it will
probably be back even further where CONFIG_PRINTK was introduced, which
would be d59745ce3e7a (2005 vintage). The ia64 debug option predates
git, so it isn't at fault (and you can't blame it anyway).
Honestly, realize this is just for a randconfig for ia64 where PRINTK is
disabled - something that will never be done in any of the remaining
ia64 deployments out there (if there is any). So I'd just recommend
dropping the Fixes tag and move on. It isn't like there is a lot of
people out there doing randconfig builds on linux-stable releases.
Paul.

Yes, I like the idea of dropping the Fixes: tag also. Thanks.
Guess I'll send a v3.

I could take it via printk tree. I am going to wait 2-3 more days
just in case anyone has a comment.
Feel free to send v3 but I could just remove the tag when pushing v2.

Hi Petr,
Please just remove the Fixes: tag after waiting a few more days
for comments.
