* 0day explit mitigation * Memory corruption prevention * Privilege escalation prevention * Buffer over flow prevention * File System corruption defense * Thread escape prevention This may very well be the most intensive inclusion to BrooklynR. This will not be part of an x86 suite nor it will be released as tool kit. The security core toolkit will remain part of kernel base.

/* pxa3xx keypad platform specific parameters
|
|
*
|
|
* NOTE:
|
|
* 1. direct_key_num indicates the number of keys in the direct keypad
|
|
* _plus_ the number of rotary-encoder sensor inputs, this can be
|
|
* left as 0 if only rotary encoders are enabled, the driver will
|
|
* automatically calculate this
|
|
*
|
|
* 2. direct_key_map is the key code map for the direct keys, if rotary
|
|
* encoder(s) are enabled, direct key 0/1(2/3) will be ignored
|
|
*
|
|
* 3. rotary can be either interpreted as a relative input event (e.g.
|
|
* REL_WHEEL/REL_HWHEEL) or specific keys (e.g. UP/DOWN/LEFT/RIGHT)
|
|
*
|
|
* 4. matrix key and direct key will use the same debounce_interval by
|
|
* default, which should be sufficient in most cases
|
|
*
|
|
* pxa168 keypad platform specific parameter
|
|
*
|
|
* NOTE:
|
|
* clear_wakeup_event callback is a workaround required to clear the
|
|
* keypad interrupt. The keypad wake must be cleared in addition to
|
|
* reading the MI/DI bits in the KPC register.
