Subject: ide: add "ignore_cable" parameter (take 2)
X-Git-Tag: v2.6.26-rc1~1029^2~47
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fd91d959f1a19d1bfa46d97cbbbb55641ce26a6;p=pandora-kernel.git

ide: add "ignore_cable" parameter (take 2)

Add "ignore_cable" parameter:

* "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in
  (i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1")

* "ignore_cable=[interface_number]" module parameter (for ide_core module)
  if IDE is compiled as module

v2:
* Add ide_port_apply_params() helper
  - use it in ide_device_add_all() and ide_scan_port().

* Make it possible to later disable ignoring cable detection by passing
  "[interface_number]:0" to /sys/module/ide_core/parameters/ignore_cable
  (however sysfs interface is not enabled yet since it needs some other
   IDE changes to make it work reliable).
