3 second faster load and uncompress time for small kernel
(5.6M uncompressed, 2.1M gz and 1.6M xz). Compression method is
autodetect by the filename suffix or can be set by the '--compression'
command line option.
Also supports uncompressed payloads (no auto detection).

mmu: map device memory as non-executable
...
This fixes the random SErrors after returning from a page fault. Turns
out the M1 was randomly deciding to speculate an instruction fetch from
address 0, triggering a fabric error.
Quoting the ARM ARM:
"Hardware does not prevent speculative instruction fetches from a memory
location with any of the Device memory attributes unless the memory
location is also marked as Execute-never for all Exception levels.
This means that to prevent speculative instruction fetches from memory
locations with Device memory attributes, any location that is assigned
any Device memory type must also be marked as execute-never for all
Exception levels. Failure to mark a memory location with any Device
memory attribute as execute-never for all Exception levels is a
programming error."
