PS7, Line 122: * @param pat The pattern to write to the pyhsical memory
> It the same what regular memset does.
I don't get your point. Regular memset declares
it as `int c` (c for char, I suppose). `unsigned int`
makes it look like you need the space, IMHO. Also,
memset(3) on my system mentions `byte` multiple
times. So it doesn't seem hard to document what it
does.

You mean a PDE pointing to a page table (PT)?
> That MASK for PAE 2MiB PDE mode is ~((1UL << PDE_IDX_SHIFT) - 1).
Right, I was confused by the macro name. *_ADDR_MASK
here is just a PAGE_MASK, i.e. always masking the lowest
12 bits out. Don't know why these macros exist.
Just tried to reason what difference it makes... none.
Because the masking here is a no-op anyway (dest is
already 2MiB aligned).

File src/cpu/x86/pae/pgtbl.c:

PS8, Line 157: ((dest < pgtbl_e) && (dest + length > pgtbl_e))) {
This is usually simpler. If you have two ranges [a, b) and
[s, e), they overlap if a < e and b > s. I find it easier
to reason about the non-overlapping case, that is either
[a, b) is completely below [s, e) or completely above:
(a < s && b <= s) || (a >= e && b > e)
b <= s implies a < s, so we can scratch the latter. same for
the other pair:
(b <= s) || (a >= e)
inverted (overlapping case) that makes:
!((b <= s) || (a >= e))
!(b <= s) && !(a >= e)
b > s && a < e
Your check seems to miss the case that [a, b) lies completely
within [s, e).
