LLVM's integrated assembler reports the following error when compiling entry.S: <instantiation>:38:5: error: unknown token in expression tm %r8,0x0001 # coming from user space? The correct instruction would have been tmhh instead of tm. The current code is doing nothing, since (with gas) it get's translated to a tm instruction which reads from real address 8, which again contains always zero, and therefore the conditional code is never executed. Note that due to the missing displacement gas translates "%r8" into "8(%r0)". Also code inspection reveals that this conditional code is not needed. Therefore remove it.

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.
