Pull strong stackprotector support from Ingo Molnar:
"This tree adds a CONFIG_CC_STACKPROTECTOR_STRONG=y, a new, stronger
stack canary checking method supported by the newest GCC versions (4.9
and later).
Here's the 'intensity comparison' between the various protection
modes:
- defconfig
11430641 kernel text size
36110 function bodies
- defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR
11468490 kernel text size (+0.33%)
1015 of 36110 functions are stack-protected (2.81%)
- defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch
11692790 kernel text size (+2.24%)
7401 of 36110 functions are stack-protected (20.5%)
the strong model comes with non-trivial costs, which is why we
preserved the 'regular' and 'none' models as well"
