25492a0f04 Add wbinvd around bios call. 
Via C3 has problems with cache coherency when transitioning between the modes,
so flush it around bios calls.

080a20861c OBP available region contains grub. Start at grub_phys_end. 
This prevents a problem where grub was being overwritten since
grub_phys_start does not start at a zero offset within the memory
map.

342d6edb97 yylex: use grub_fatal for exit. 
lexer calls yylex_fatal on fatal internal errors. yylex_fatal itself is
declared as noreturn and calls exit. Returning from noreturn function has
unpredictable consequences.

67dba97e45 support modules without symbol table 
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.

Closes: 46986

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

7290bb5623 10_linux: avoid multi-device root= kernel argument 
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.

Closes: 45709

47e67d809c Remove pragmas related to -Wunreachable-code 
-Wunreachable-code has been a no-op since GCC 4.5; GRUB hasn't been
compiled with it since 2012; and GCC 6 produces "error:
'-Wunreachable-code' is not an option that controls warnings" for these.

Fixes Debian bug #812047.
