PR_MCE_KILL_SET - set the machine check memory corruption kill policy

Use a thread-specific memory corruption kill policy. pol defines whether the policy is earlykill (PR_MCE_KILL_EARLY), latekill (PR_MCE_KILL_LATE), or the system-wide default (PR_MCE_KILL_DEFAULT). Early kill means that the thread receives a SIGBUS signal as soon as hardware memory corruption is detected inside its address space. In late kill mode, the process is killed only when it accesses a corrupted page. See sigaction(2) for more information on the SIGBUS signal.

EINVALpol is not a valid value.
