[MIPS] Discard .exit.text at runtime. (bb7d83f7) · Commits · 戴 / test

At times gcc will place bits of __exit functions into .rodata. If compiled into the kernle itself we used to discard .exit.text - but not the bits left in .rodata. While harmless this did at times result in a large number of warnings. So until gcc fixes this, discard .exit.text at runtime. Signed-off-by:
