3d8df86d82 ls: prevent double open 
Prevent a double open.  This can cause problems with some ieee1275
devices, causing the system to hang.  The double open can occur
as follows:

grub_ls_list_files (char *dirname, int longlist, int all, int human)
       dev = grub_device_open (device_name);
       dev remains open while:
       grub_normal_print_device_info (device_name);
                dev = grub_device_open (name);

4bd4a88725 i386, x86_64, ppc: fix switch fallthrough cases with GCC7 
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.

Closes: 50598

c79c59f129 lsefimmap: support persistent memory and other UEFI 2.5 features 
This should accompany
	76ce1de740 Translate UEFI persistent memory type

1. Add a string for the EfiPersistentMemory type 14 that was
added in UEFI 2.5.

2. Decode the memory attributes that were added in UEFI 2.5:
* NV (non-volatile)
* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
  with partial memory mirroring)
* RO (read-only)

3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
values rather than misusing SI power-of-ten units (KB, MB, etc.)

4. The lsmmap command only decodes memory ranges sizes up to GiB scale
units.  Persistent memory ranges will reach into the TiB scale.
Since 64-bit size field supports TiB, PiB, and EiB, decode all of
them for completeness.

5. In the lsefimmap command, rewrite the print statements to
* avoid rounding
* avoid a big nested if/else tree.

For example: In the sixth entry below, the value of 309MB implies
316416KB but is really reporting 316436KB.

Widen the size column to 6 digits to accommodate typical cases.
The worst case value would require 14 digits; if that happens,
let the columns get out of sync.

76ce1de740 Translate UEFI persistent memory type 
Define
* GRUB_EFI_PERSISTENT_MEMORY (UEFI memory map type 14) per UEFI 2.5
* GRUB_MEMORY_PERSISTENT (E820 type 7) per ACPI 3.0
* GRUB_MEMORY_PERSISTENT_LEGACY (E820 unofficial type 12) per ACPI 3.0

and translate GRUB_EFI_PERSISTENT_MEMORY to GRUB_MEMORY_PERSISTENT in
grub_efi_mmap_iterate().

Includes
* adding the E820 names to lsmmap
* handling the E820 types in make_efi_memtype()

d43a5ee651 tsc: Use alternative delay sources whenever appropriate. 
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.
