Re-organize handling of quirky devices:
* Add struct cd_list_entry, ide_cd_quirks_list[] and ide_cd_flags() helper.
* Set flags returned by ide_cd_flags() in ide_cdrom_setup().
* Add IDE_CD_FLAG_VERTOS_{300_SDD,600_ESD} and IDE_CD_FLAG_SANYO_3CD flags.
* Move device quirks from ide_cdrom_setup() to ide_cd_quirks_list[].
* Rename IDE_CD_FLAG_NEC260 to IDE_CD_FLAG_PRE_ATAPI12 and handle
quirky Stingray 8X CD-ROM using ide_cd_quirks_list[].
* Add IDE_CD_FLAG_FULL_CAPS_PAGE flag and handle quirky ACER 50X CD-ROM
/ WPI 32X CD-ROM using ide_cd_quirk_list[].
* Add IDE_CD_FLAG_PLAY_AUDIO_OK flag and handle quirky MATSHITA DVD-ROMs
using ide_cd_quirks_list[].

CD-ROM using ide_cd_quirk_list[].
* Fix some comments about quirky devices while at it.

ide_cd_probe() zeroes 'info' prior to calling ide_cdrom_setup() so there
is no need to explicitly zero 'info' fields in the latter function.
Ditto for fields of CDROM_STATE_FLAGS(), CDROM_CONFIG_FLAGS() and 'cdi'
(all are embedded in 'info').

ide: drop 'initializing' argument from ide_register_hw()
* Rename init_hwif_data() to ide_init_port_data() and export it.
* For all users of ide_register_hw() with 'initializing' argument set
hwif->present and hwif->hold are always zero so convert these host
drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw()
instead (also no need for init_hwif_default() call since the setup
done by it gets over-ridden by ide_init_port_hw() call).
* Drop 'initializing' argument from ide_register_hw().
introduced the usage of a hwif variable, but forgot to declare the actual
variable.

some printk messages from the audit system can become excessive. This
patch ratelimits those messages. It was found that messages, such as
the audit backlog lost printk message could flood the logs to the point
that a machine could take an nmi watchdog hit or otherwise become

Currently audit drops the audit type when an audit message goes through
printk instead of the audit deamon. This is a minor annoyance in
that the audit type is no longer part of the message and the information
the audit type conveys needs to be carried in, or derived from the
message data.
The attached patch includes the type number as part of the printk.
Admittedly it isn't the type name that the audit deamon provides but I
think this is better than dropping the type completely.

This patch adds an end of event record type. It will be sent by the kernel as
the last record when a multi-record event is triggered. This will aid realtime
analysis programs since they will now reliably know they have the last record
to complete an event. The audit daemon filters this and will not write it to
disk.
