arch/tile: various header improvements for building drivers
This change adds a number of missing headers in asm (fb.h, parport.h, serial.h, and vga.h) using the minimal generic versions. It also adds a number of missing interfaces that showed up as build failures when trying to build various drivers not normally included in the "tile" distribution: ioremap_wc(), memset_io(), io{read,write}{16,32}be(), virt_to_bus(), bus_to_virt(), irq_canonicalize(), __pte(), __pgd(), and __pmd(). I also added a cast in virt_to_page() since not all callers pass a pointer. I fixed <asm/stat.h> to properly include a __KERNEL__ guard for the __ARCH_WANT_STAT64 symbol, and <asm/swab.h> to use __builtin_bswap32() even for our 64-bit architecture, since the same code is produced. I added an export for get_cycles(), since it's used in some modules. And I made <arch/spr_def.h> properly include the __KERNEL__ guard, even though it's not yet exported, since it likely will be soon. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
