* 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.

|
* @host_caps2: The second standard MMC host capabilities bit field.
|
|
* @cd_type: Type of Card Detection method (see cd_types enum above)
|
|
* @ext_cd_init: Initialize external card detect subsystem. Called on

* sdhci-s3c driver probe when cd_type == S3C_SDHCI_CD_EXTERNAL.
|
|
* notify_func argument is a callback to the sdhci-s3c driver
|

* that triggers the card detection event. Callback arguments:
|
|
* dev is pointer to platform device of the host controller,
|
|
* state is new state of the card (0 - removed, 1 - inserted).
|
|
* @ext_cd_cleanup: Cleanup external card detect subsystem. Called on
|
|
* sdhci-s3c driver remove when cd_type == S3C_SDHCI_CD_EXTERNAL.
|
|
* notify_func argument is the same callback as for ext_cd_init.
|
|
* @ext_cd_gpio: gpio pin used for external CD line, valid only if
|
|
* cd_type == S3C_SDHCI_CD_GPIO
|
|
* @ext_cd_gpio_invert: invert values for external CD gpio line
|
|
* @cfg_gpio: Configure the GPIO for a specific card bit-width
|
|
*
|
|
* Initialisation data specific to either the machine or the platform
|
|
* for the device driver to use or call-back when configuring gpio or
|
|
* card speed information.
