thuge-gen.c defines SHM_HUGE_* macros that are provided by the uapi since
4.14. These macros get redefined when compiling with Android's bionic
because its sys/shm.h will import the uapi definitions.
However if linux/shm.h is included, with glibc, sys/shm.h will clash on
some struct definitions:
/usr/include/linux/shm.h:26:8: error: redefinition of ‘struct shmid_ds’
26 | struct shmid_ds {
| ^~~~~~~~
In file included from /usr/include/x86_64-linux-gnu/bits/shm.h:45,
from /usr/include/x86_64-linux-gnu/sys/shm.h:30:
/usr/include/x86_64-linux-gnu/bits/types/struct_shmid_ds.h:24:8: note: originally defined here
24 | struct shmid_ds
| ^~~~~~~~
For now, guard the SHM_HUGE_* defines with ifndef to prevent redefinition
warnings on Android bionic.

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.
