Ah. The spec explains the enlargement. The allocation of the target
buffer itself may increase the map size.

<pedantic>
I think you could also ensure that the loop not run out of e820_map
elements (128). Unlikely, admittedly...
Plus I think here we're modifying *Bp (the e820_map array is contained
in it), therefore Bp is an OUT parameter here. The prototypes of
SetupLinuxBootParams() and LoadLinux() should be probably modified
accordingly.

In fact KernelSetup should be OUT (or IN/OUT) here.

Same.
Plus these two functions return constant EFI_SUCCESS, and don't check
for support level (the header documents EFI_UNSUPPORTED too).

Maybe check if BzImageSize >= sizeof (*Bp)?

(Pedantic again) We could compare (BzImageSize - SetupSize) against
SIZE_8MB first.

I'll continue from here later.
