Our PV guest patching code assembles chunks of instructions on the fly when it encounters more complicated instructions to hijack. These instructions need to live in a section that we don't mark as non-executable, as otherwise we fault when jumping there. Right now we put it into the .bss section where it automatically gets marked as non-executable. Add a check to the NX setting function to ensure that we leave these particular pages executable.
