This shouldn't be necessary. The old 64-bit code defined everything
without _PAGE_GLOBAL, but then used a MAKE_GLOBAL() macro to OR it in
later. This seemed a bit roundabout to me, so I just put it in from the
outset.
btw., __PAGE_KERNEL_EXEC should probably be _PAGE_GLOBAL - but it wasnt
before.
You mean _PAGE_KERNEL_EXEC, which is assigned to the 32-bit
__PAGE_KERNEL_EXEC variable? It gets ORed in when it determines that
the processor has the global capability.
If not, I'm not sure what you mean.
