Subject: Fix missing parens in set_personality()
From: Russell King <rmk+lkml@xxxxxxxxxxxxxxxx>
If you call set_personality() with an expression such as:
set_personality(foo ? PERS_FOO1 : PERS_FOO2);
then this evaluates to:
((current->personality == foo ? PERS_FOO1 : PERS_FOO2) ? ...
which is obviously not the intended result. Add the missing parents
to ensure this gets evaluated as expected:
((current->personality == (foo ? PERS_FOO1 : PERS_FOO2)) ? ...
