In case of GRUB we put remapper after domain pages and not at 0x0.
In this case we use max_addr to put remapper. Unfortunately we increment
max_addr as well in this case resulting in virt mapping mapping page
at old max_addr and trying to boot using new max_addr.
Closes 46014.
The current documentation for the special environment variable
"default" is confusing and unclear. This patch attempts to clean it
up.
In particular, the current documentation refers to the "number or
title", but then in the example it gives, the menu entries and
submenus all have numbers *in* their title; furthermore, there is no
example given about how to choose the number, or any indication about
whether counting is zero-indexed or 1-indexed.
Having a cleaner example and presenting all variants (numeric, title,
and id) should make it clearer to the user.

Unified Extensible Firmware Interface Specification, Version 2.6,
section 2.3.4, x64 Platforms, boot services, says among others:
The stack must be 16-byte aligned. So, do it. Otherwise OS may
boot only by chance as it happens right now.

According to EABI only STT_FUNC has convention of lowest bit indicating
execution mode. R_THM_{JUMP,CALL}* relocations are assumed to be pointing
to thumb mode unless they use STT_FUNC.
We need -static as otherwise linker will set interpreter field and ld.so
is not available on our initrd's.
Strip all sections we don't need on binary tests.
If ascent is bigger than height - 2, then we draw over character box but then
to clear cursor we only draw over character box. So trim ascent if necessarry.
We don't use lgcc_s but missing lgcc_s or another library cause test to fail.
So use -nostdlib.
We need to use -Werror to avoid warning-generated case to be accepted.
Clang uses -nopie rather than -no-pie. Check both and use whichever one works.
Additionally android clang passes -pie to the linker even though it doesn't
define __PIE__. So if compilation without no-pie logic fails add -nopie/-no-pie
even if __PIE__ is not defined.
clang 3.8 and later doesn't support -mllvm -use-arm-movt=0
whereas older clang doesn't know -mno-movt. So use
-mno-movt whenever possible and fallback to mllvm variant.
proot creates hidden files with .proot prefix and name
derived from real file name. So decrease file name length
and path depth. For some reason depth 85 also results in
undeleteable directory, so use 84 instead of 85.
o Add some comments.
o Change image buffer type to (const void *).
o Add new macro VERITY_CMDLINE_LENGTH.
