The ia64 handling of failure to return from a signal frame has been trying to set overlapping fields in struct siginfo since 2.3.43. The si_code corresponds to the fields that were stomped (not the field that is actually written), so I can not imagine a piece of userspace code making sense of the signal frame if it looks closely. In practice failure to return from a signal frame is a rare event that almost never happens. Someone using an alternate signal stack to recover and looking in detail is even more rare. So I presume no one has ever noticed and reported this ia64 nonsense. Sort this out by causing ia64 to use force_sig(SIGSEGV) like other architectures.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
