/*TempleOS does not mess with page tables after it
identity-maps them during boot -- $LK,"SYS_INIT_MEM",A="MN:SYS_INIT_MEM"$.
$LK,"PAGE_SIZE",A="MN:PAGE_SIZE"$ is arbitrary, and is not related to CPU hardware.
I need some unit for memory allocation so I invented "$LK,"PAGE_SIZE",A="MN:PAGE_SIZE"$".

All virtual addresses are identical to physical, always.
There is no high kernel memory because RAM's physical
addresses are low.  (All motherboards that I know of
put RAM in low addresses of 64-bit address space.)
It's ring-0-only so all (or none) is kernel, remember.

2 Meg hardware pages are use except the first 2 Meg.
0xA0000-0xBFFFF must be write thru.  Hardware pages
don't matter except the caching bit.	Remember, it is ring-0-only
and identity-mapped!	Do I need to repeat?
Ring-0-only and 100% identity-mapped, all the time.

All code is placed in just the lowest 2 Gig, so the CALL REL32
instruction always works.  It never changes out of ring-0, remember,
so I don't need to waste cycles on use SYSCALL or software interrupts.
Everything just uses CALL REL32.
