[kvm-unit-tests PATCH v3 00/18] arm64: EFI improvements

[Andrew Jones <andrew.jones@linux.dev>]

This series collects one fix ("Update MAX_SMP probe") with a bunch of
improvements to the EFI setup code and run script. With the series
applied one can add --enable-efi-direct when configuring and then
run the EFI tests on QEMU much, much faster by using direct kernel
boot for them (and environment variables will work too). The non-
direct (original) way of running the EFI tests has also been sped up
a bit by not running the dummy test and not generating the dtb twice.
The cleanups in the setup code allow duplicated code to be removed
(by sharing with the non-EFI setup code) and eventually for riscv
to share some code too with the introduction of memregions_efi_init().

v3:
 - Dropped fdt_valid
 - Factored out qemu_args+=(-machine acpi=off) [Nikos]
 - Ensure etext is page aligned
 - Picked up Nikos's r-b's

v2:
 - Add another improvement (patches 15-17), which is to stop mapping
   EFI regions which we consider reserved (including
   EFI_BOOT_SERVICES_DATA regions which requires moving the primary stack)
 - Add EFI gitlab CI tests
 - Fix one typo in configure help text
