269a522c7d hostdisk: fix device detection 
Condition was apparently reversed so GRUB assumed all devices were
files. This later made it skip BLKFLSBUF ioctl on Linux which caused
various page cache coherency issues. Observed were

- failure to validate blocklist install (read content did not match
  just written)

- failure to detect Linux MD on disk after online hot addition
  (GRUB got stale superblock)

7eb27a49e9 arm-efi: Reduce timer event frequency by 10 
Timer event to keep grub msec counter was running at 1000HZ. This was too
fast for UEFI timer driver and resulted in a 10x slowdown in grub time
versus wallclock. Reduce the timer event frequency and increase tick
increment accordingly to keep better time.

3b21499506 Disable build-time module check on emu. 
On emu some checks can be laxer like check for relocation range. Additionally
module loading in emu is rarely used. So skip this check rather than making
it laxer for all platforms. In ideal we may want to have slightly different
check for emu but for now this is good enough.

3bca85b418 devmapper: check for valid device abstraction in get_grub_dev 
This was lost when code was refactored. Patch restores previous behavior.

It is still not clear whether this is the right one. Due to the way we
detect DM abstraction, partitions on DM are skipped, we fall through to
generic detection which ends up in assuming parent device is BIOS disk.

It is useful to install GRUB on VM disk from the host. But it also means
that GRUB will mistakenly allow install on real system as well.

For now let's fix regression; future behavior needs to be discussed.

a9399f2e1e windows: correct LBA in generated EFI HDD media paths 
GRUB keeps partition offset and size in units of 512B sectors. Media paths
are defined in terms of LBA which are presumed to match HDD sector size.

This is probably cosmetic (EFI requires that partition is searched by GUID)
and still incorrect if GPT was created using different logical block size.
But current code is obviously wrong and new has better chances to be correct.

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.
