GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage. This branch does the work to completely eliminate GENERIC_GPIO. However, it is not trivial to just create a branch to remove it. Over the course of the v3.9 cycle more code referencing GENERIC_GPIO has been added to linux-next that conflicts with this branch. The following must be done to resolve the conflicts when merging this branch into mainline: * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be replaced with CONFIG_GPIOLIB * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese documentation. * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB * definitions of the option in architecture Kconfig code should be deleted. Stephen has 3 merge fixup patches[1] that do the above. They are currently applicable on mainline as of May 2nd.

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this

|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
