Code is currently ignoring errors from efibootmgr, giving users
clearly bogus output like:

Could not delete variable: No space left on device
Could not prepare Boot variable: No space left on device
Installation finished. No error reported.
and then potentially unbootable systems. If efibootmgr fails, grub-install
should know that and report it!
We've been using similar patch in Debian now for some time, with no ill effects.

Add block-list GPT support for SPARC. The OBP "load" and "boot" methods
are partition aware and neither command can see the partition table. Also
neither command can address the entire physical disk. When the install
happens, grub generates the block-list entries based on the beginning of the
physical disk, not the beginning of the partition. This patch fixes the
block-list entries so they match what OBP expects during boot for a GPT disk.
T5 and above now supports GPT as well as VTOC.
This patch has been tested on T5-2 and newer SPARC systems.

grub-mkconfig will set GRUB_TERMINAL_OUTPUT to "gfxterm" unless the user
has overridden it. On EFI systems, this will stop output from going to the
default "console" terminal. When the EFI fw console is configured to output to
both serial and video, this will cause GRUB to only display on video - while
continuing to accept input from both video and serial.
Instead of switching from "console" to "gfxterm", let's output to both.

Commit d33045ce7f introduced
the support for this, but it does not work under x86 (as it stops
20_linux_xen from running).
The 20_linux_xen is run under a shell and any exits from within it:
(For example on x86):
+ /usr/bin/grub2-file --is-arm64-efi /boot/xen-4.9.0.gz
[root@tst063 grub]# echo $?
1
will result in 20_linux_xen exiting without continuing
and also causing grub2-mkconfig to stop processing.
As in:
[root@tst063 grub]# ./grub-mkconfig | tail

This patch adds the support of xen_boot command for aarch64:
xen_hypervisor
xen_module
These two commands are only for aarch64, since it has its own protocol and
commands to boot xen hypervisor and Dom0, but not multiboot.
For other architectures, they are still using multiboot and module
commands.

In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.
In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.
In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.
In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).
Otherwise add FALLTHROUGH comment.

According to EABI only STT_FUNC has convention of lowest bit indicating
execution mode. R_THM_{JUMP,CALL}* relocations are assumed to be pointing

Grub would notify the user if the new config was invalid, however, it
did not exit properly with exit code 1. Added the proper exit code.

all_video module does not have any code or data and exists solely for
.moddeps section to pull in dependencies. This makes all symbols unneeded.
While in current binutils (last released version as of this commit is 2.26)
``strip --strip-unneeded'' unintentionally adds section symbols for each
existing section, this behavior was considered a bug and changed in commit
14f2c699ddca1e2f706342dffc59a6c7e23e844c to completely strip symbol table
in this case.
Older binutils (verified with 2.17) and some other toolchains (at least
elftoolchain r3223M), both used in FreeBSD, remove symbol table in all_video
as well.
Relax run-time check and do not return error for modules without symbol table.
Add additional checks to module verifier to make sure such modules
a) have non-empty .moddeps section. Without either externally visible symbols
or .moddeps modules are completely useless and should not be built.
b) do not have any relocations.

v2: add run-time check for empty symbol table if relocations are present as

If root filesystem is multidev btrfs, do not attempt to pass all devices as
kernel root= argument. This results in splitting command line in GRUB due to
embedded newline and even if we managed to quote it, kernel does not know how
to interpret it anyway. Multidev btrfs requires user space device scanning,
so passing single device would not work too.
This still respects user settings GRUB_DISABLE_LINUX_UUID. Not sure what we
should do in this case.

Currently only Windows gets distinguished icons, everything else is displayed
using the same generic one. Add additional --class based on os-prober returned
label, which usually is expected to match primary distribution name.
Also use it for Windows as well - chainloader prober may actually return
different strings (Windows, MS-DOS, Windows9xME).
This did not cause real problem but is good for reproducible builds. I hit
it with recent bootinfoscript that displays embedded config; I was puzzled
by random garbage at the end.
