I think this statement is slightly misleading.
The problem may have manifested when building for ia64 config.
However, I don't believe that it is, strictly speaking, an ia64 issue.
Rather, I believe the problem is build without CONFIG_RTC_LIB.
Some architectures select CONFIG_RTC_LIB., f.e. x86_64. But some do not.
ia64 is one such example. arm64 is another - indeed I was able to reproduce
the bug when building for arm64 using config based on the one at the link
below.
I think it would be helpful to update the patch description accordingly.
Code change looks good to me: I exercised builds for both ia64 and arm64.
