--- Comment #3 from Sebastian Lackner <sebastian at fds-team.de> ---
I have added a patch to workaround this warning, so it will disappear again
with the next release. Please note that the warning is harmless, and can be
safely ignored.

Even before 2.10, Wine already tried to allocate this memory region, which is
necessary for running DOS applications. A failure is not critical, except that
you will lack support for running such apps. The warning appeared because of a
change related to the preloader on macOS. We splitted the allocation of the DOS
area (0x0 - 0x10000) into two separate allocations.

Although both methods are technically identical, the SELinux code is written in
such a way that only the new method will trigger a warning. By looking at the
kernel code, it only seems to affects kernel versions compiled with
CONFIG_DEFAULT_MMAP_MIN_ADDR < CONFIG_LSM_MMAP_MIN_ADDR.
