Linux kernel source tree

STATIC_CALL_TRAMP_STR() could not be used from .S files because static_call_types.h was not safe to include in assembly as it pulled in C types/constructs that are unavailable under __ASSEMBLY__. Make the header assembly-friendly by adding __ASSEMBLY__ checks and providing only the minimal definitions needed for assembly, so that it can be safely included by .S code. This enables emitting the static call trampoline symbol name via STATIC_CALL_TRAMP_STR() directly in assembly sources, to be used with 'call' instruction. Also, move a certain definitions out of __ASSEMBLY__ checks in compiler_types.h to meet the dependencies. No functional change for C compilation.

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 reStructuredText 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.
