bb84dbf69b Blackfin: punt Blackfin-specific GPIO wakeup API
This patch removes a custom GPIO wakeup API which allowed GPIOs to act
as wakeup sources, which are not configured as Interrupts.
This API is a leftover from the time before irq_wake was established.
From now on people must use enable_irq_wake(GPIO_IRQx) and the GPIO in
question needs to be configured as Interrupt.

f074e48e0a Blackfin: drop unused bad_page pages and move zero_page to the bss
The empty_bad_page/empty_bad_page_table pages are unused, so punt them.
The zero_page is always allocated, so push it out to the bss to speed up
the booting process a bit and pack data nicer.

39f2f080b3 usb-storage: always print quirks
Right now quirks are printed only when the are manually overriden with
the module parameters. It's not so useful to remind the user that his
parameters are correctly applied; what is useful is to print out the
quirks the user is not aware are being applied.

So let's do the smart thing and print the quirks when they are present.
