releasepage: releasepage is called on PagePrivate pages to indicate
that the page should be freed if possible. ->releasepage
should remove any private data from the page and clear the
PagePrivate flag. It may also remove the page from the
address_space. If this fails for some reason, it may indicate
failure with a 0 return value.
This is used in two distinct though related cases. The first
is when the VM finds a clean page with no active users and

indicate failure with a 0 return value.
releasepage() is used in two distinct though related cases. The
first is when the VM finds a clean page with no active users and
wants to make it a free page. If ->releasepage succeeds, the
page will be removed from the address_space and become free.

This driver implements support for buttons connected
to GPIO pins that are not capable of generating interrupts.
Say Y here if your device has buttons connected
directly to such GPIO pins. Your board-specific
setup logic must also provide a platform device,
with configuration data saying which GPIOs are used.
