Warning: disabling this option may break 32-bit user programs.
Provide kuser helpers to compat tasks. The kernel provides
helper code to userspace in read only form at a fixed location
to allow userspace to be independent of the CPU type fitted to
the system. This permits binaries to be run on ARMv4 through
to ARMv8 without modification.
See Documentation/arm/kernel_user_helpers.rst for details.
However, the fixed address nature of these helpers can be used
by ROP (return orientated programming) authors when creating
exploits.
If all of the binaries and libraries which run on your platform
are built specifically for your platform, and make no use of
these helpers, then you can turn this option off to hinder
such exploits. However, in that case, if a binary or library
relying on those helpers is run, it will not function correctly.
Say N here only if you are absolutely certain that you do not
need these helpers; otherwise, the safe option is to say Y.
