The function viafb_cursor() uses 2 stack-variables of CURSOR_SIZE bits; CURSOR_SIZE is defined as (8 * 1024). Using up twice 1k on stack is too much for 4k-stack (though it works with 8k-stacks). Make those two variables kzalloc'ed to preserve stack space. Also merge the whole lot of local struct's in viafb_ioctl into a union so the stack usage gets minimized here as well. (struct's are only accessed in their indicidual IOCTL case) This second part is only compile-tested as I know of no userspace app using the IOCTLs.
