mainlining shenanigans
5496295aef
We currently allow signals to interrupt the wait for management FW
commands. Exiting the wait should not cause trouble, the FW will
just finish executing the command in the background and new commands
will wait for the old one to finish.
However, this may not be what users expect (Ctrl-C not actually stopping
the command). Moreover some systems routinely request link information
with signals pending (Ubuntu 14.04 runs a landscape-sysinfo python tool
from MOTD) worrying users with errors like these:
nfp 0000:04:00.0: nfp_nsp: Error -512 waiting for code 0x0007 to start
nfp 0000:04:00.0: nfp: reading port table failed -512
Make the wait for management FW responses non-interruptible.
Fixes:

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.
