Geeze. Here's what I came up with, mainly to make i386 compile:


From: Andrew Morton <akpm@linux-foundation.org>
Subject: drivers/block/skd_main.c: fix a few things, disable on 32-bit

Fix these (i386 allmodconfig):

drivers/block/skd_main.c:4559: warning: format '%lu' expects type 'long unsigned int', but argument 5 has type 'unsigned int'
drivers/block/skd_main.c:4614: warning: format '%lu' expects type 'long unsigned int', but argument 5 has type 'unsigned int'
drivers/block/skd_main.c:4614: warning: format '%lu' expects type 'long unsigned int', but argument 7 has type 'unsigned int'
drivers/block/skd_main.c:4626: warning: format '%lu' expects type 'long unsigned int', but argument 6 has type 'unsigned int'
drivers/block/skd_main.c:4626: warning: format '%lu' expects type 'long unsigned int', but argument 7 has type 'unsigned int'
drivers/block/skd_main.c:4671: warning: format '%lu' expects type 'long unsigned int', but argument 5 has type 'unsigned int'
drivers/block/skd_main.c:4671: warning: format '%lu' expects type 'long unsigned int', but argument 7 has type 'unsigned int'

And what remains is these:

drivers/block/skd_main.c: In function 'skd_reg_write64':
drivers/block/skd_main.c:439: error: implicit declaration of function 'writeq'
drivers/block/skd_main.c:441: error: implicit declaration of function 'readq'
drivers/block/skd_main.c: In function 'skd_cons_skmsg':
drivers/block/skd_main.c:4589: warning: cast from pointer to integer of different size
drivers/block/skd_main.c:4592: warning: cast from pointer to integer of different size
drivers/block/skd_main.c:4593: warning: cast to pointer from integer of different size

Which is more than I'm prepared to address, so just disable the driver on
32-bit builds.
