struct ... foo = { 0, } is valid initializer, but older GCC emits
warning which is fatal error due to -Werror=missing-field-initializer.
So simply use full initializer to avoid these errors. This was fixed
probably in GCC 4.7.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750
This makes it possible to build generally-useful utilities such as
grub-mount even if the rest of GRUB has not been ported to the target
CPU.
* configure.ac: Add "none" platform. Default to it for unsupported
CPUs rather than stopping with a fatal error. Don't downgrade
x86_64-none to i386. Define COND_real_platform Automake conditional
if the platform is anything other than "none". Don't do any include
directory linking for "none".
* Makefile.am: Skip building grub-core and all bootcheck targets if
!COND_real_platform.
* include/grub/time.h: Don't include <grub/cpu/time.h> if GRUB_UTIL
is defined.
The AML parser implements only a small subset of possible AML
opcodes. On the Fujitsu Lifebook E744 this and another bug in
the parser (incorrect handling of TermArg data types) would lead
to the laptop not turning off (_S5 not found).
* grub-core/commands/acpihalt.c: Support OpAlias in the AML parser;
in skip_ext_op(), handle some Type2Opcodes more correctly (TermArgs
aren't always simply strings!); Add function to skip TermArgs
* include/grub/acpi.h: Add new opcodes
Currently, if "linux" fails, the "goto fail;" in grub_cmd_initrd sends us
into grub_initrd_close() without grub_initrd_init() being called, and thus
it never clears initrd_ctx->components. grub_initrd_close() then frees that
address, which is stale data from the stack. If the stack happens to have a
stale *address* there that matches a recent allocation, then you'll get a
double free later.
So initialize the memory up front.

We encountered a weird random kernel initrd unpacking error on btrfs
and finally found it was caused by incorrect address reference in range
check for type GRUB_BTRFS_EXTENT_REGULAR and the entire result is
unpredictable.
This is a quick fix to make the address reference to the
grub_btrfs_extent_data structure correctly, not the pointer variable
to it.
Any suggestions to this patch is welcome.
* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone. These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.
* util/grub.d/30_os-prober.in: Tolerate devices with no filesystem
UUID. Other parts of grub-mkconfig tolerate these, they were
previously allowed here up to commit
55e706c918, and they can arise in
practice when the system has active LVM snapshots.
Fixes Ubuntu bug #1287436.
Commit 588744d0dc caused grub-mkconfig
no longer to be forgiving of trailing spaces on grub-probe output
lines, which among other things means that util/grub.d/10_linux.in
no longer detects LVM. To fix this, make grub-probe's output
delimiting more consistent. As a bonus, this improves the coverage
of the -0 option.
Fixes Debian bug #735935.
* grub-core/disk/cryptodisk.c
(grub_util_cryptodisk_get_abstraction): Add a user-data argument.
* grub-core/disk/diskfilter.c (grub_diskfilter_get_partmap):
Likewise.
* include/grub/cryptodisk.h (grub_util_cryptodisk_get_abstraction):
Update prototype.
* include/grub/diskfilter.h (grub_diskfilter_get_partmap): Likewise.
* util/grub-install.c (push_partmap_module, push_cryptodisk_module,
probe_mods): Adjust for extra user-data arguments.
* util/grub-probe.c (do_print, probe_partmap, probe_cryptodisk_uuid,
probe_abstraction): Use configured delimiter. Update callers.
