mainlining shenanigans

HFI IRQ enable bits are not being set correctly. Send context error and
DC IRQs are not being enabled correctly. In addition, send context error
IRQs are not being delivered.
Because of this, send context errors are not being handled correctly when
they occur.
When setting the IRQ bits, if an IRQ range is used, and the last bit is on
a register boundary (bit 63), the calculated index for the final register
modification is incorrect (index + 1 vs. index).
The incorrect index calculation causes incorrect IRQ bits to be set. In
this case the send context error IRQ is NOT enabled.
Fix by using the 'last' value rather than the counted 'src' value to
determine the final index to use. This satisfies all cases.

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.
