[PATCH 2/5] ia64: remove HAVE_ARCH_COPY_SIGINFO

Christoph Hellwig
2017-06-03T19:02:08Z

Since ia64 defines __ARCH_SI_PREAMBLE_SIZE it can just use the generic
copy_siginfo implementation, which is identical to the architecture
specific one.

With that support for HAVE_ARCH_COPY_SIGINFO can go away entirely.
