look at what went into 2.6.25.11 for example. it's a security fix. you do
treat them differently: you include them in -stable to the exclusion of
many other 'less important' fixes. read Documentation/stable_kernel_rules.txt
for how you not treat all fixes as equal (it's not only security ones that
are special cased).

anything that breaks the kernel's security model. privilege elevation
always does.
