User Mode Linux is a flavor of x86 that from the vDSO prospective always
falls back on system calls. This implies that it does not require any
of the unified vDSO definitions and their inclusion causes side effects
like this:
In file included from include/vdso/processor.h:10:0,
from include/vdso/datapage.h:17,
from arch/x86/include/asm/vgtod.h:7,
from arch/x86/um/../kernel/sys_ia32.c:49:
>> arch/x86/include/asm/vdso/processor.h:11:29: error: redefinition of 'rep_nop'
static __always_inline void rep_nop(void)
^~~~~~~
In file included from include/linux/rcupdate.h:30:0,
from include/linux/rculist.h:11,
from include/linux/pid.h:5,
from include/linux/sched.h:14,
from arch/x86/um/../kernel/sys_ia32.c:25:
arch/x86/um/asm/processor.h:24:20: note: previous definition of 'rep_nop' was here
static inline void rep_nop(void)
Make sure that the unnecessary headers are not included when um is built
to address the problem.

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.
