According to ISAv3.1 and ISAv3.0b, the msgsndp is described to split RB in: msgtype <- (RB) 32:36 payload <- (RB) 37:63 t <- (RB) 57:63 The current way of getting 'msgtype', and 't' is missing their MSB: msgtype: ((arg >> 27) & 0xf) : Gets (RB) 33:36, missing bit 32 t: (arg &= 0x3f) : Gets (RB) 58:63, missing bit 57 Fixes this by applying the correct mask.

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.
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.
