    gcc-9: properly declare the {pv,hv}clock_page storage · 459e3a21
    Linus Torvalds authored
    The pvlock_page and hvclock_page variables are (as the name implies)
    addresses to pages, created by the linker script.
    
    But we declared them as just "extern u8" variables, which _works_, but
    now that gcc does some more bounds checking, it causes warnings like
    
        warning: array subscript 1 is outside array bounds of ‘u8[1]’
    
    when we then access more than one byte from those variables.
    
    Fix this by simply making the declaration of the variables match
    reality, which makes the compiler happy too.
