#     gcc-9: properly declare the {pv,hv}clock_page storage
#     
#     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.
