LKP reports a build issue on Clang, related to a literal load of __current issued through the ldr_va macro. This turns out to be due to the fact that group relocations are disabled when CONFIG_COMPILE_TEST=y, which means that the ldr_va macro resolves to a pair of LDR instructions, the first one being a literal load issued too far from its literal pool. Due to the introduction of a couple of new uses of this macro in commit508074607c("ARM: 9195/1: entry: avoid explicit literal loads"), the literal pools end up getting rearranged in a way that causes the literal for __current to go out of range. Let's fix this up by putting a .ltorg directive in a suitable place in the code.

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.
