    arch/tile: various header improvements for building drivers · 28d71741
    Chris Metcalf authored
    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.
