+ Provide kuser helpers in the vector page. The kernel
provides
+ helper code to userspace in read only form at a fixed
location
+ in the high vector page to allow userspace to be independent
of
+ the CPU type fitted to the system. This permits binaries to
be
+ run on ARMv4 through to ARMv7 without modification.
+
+ See Documentation/arm/kernel_user_helpers.txt 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 receive a SIGILL
signal,
+ which will terminate the program.
+
+ Say N here only if you are absolutely certain that you do not
+ need these helpers; otherwise, the safe option is to say Y.
