The conversion from a function pointer with the 'noreturn' attribute

SMBIOS specification dictates that tables should have a minimal length.
This commit introduces further validation for user-input SMBIOS tables.
As per SMBIOS Reference Specification:
* Type 0: For version 2.3 and later implementations, the length is at least 14h
* Type 1: 1Bh fo

* `sizeof_field` returns the size of a specific struct member
* `offsetof_end` returns the offset to the end of the member within the struct
It will be useful in upcoming layout checks of SMBIOS structs.

Changes since v3:
- Renamed offsetofend macro to offsetof_end.
Changes since v2:
- Added sizeof_field and offsetofend macros to common-macros.h.
- Used offsetofend macro everywhere to make semantically sense.
- Added BUILD_BUG_ON to ensure offsets are correct based on the SMBIOS

Some SMBIOS tables are used by certain malware families to detect virtualized
environments via WMI queries.
To improve stealth for sandboxing purposes, this patch adds support
for populating these SMBIOS tables from an external binary specified
via the "smbios_firmware" domain c

From: Penny Zheng
In the function `init_staticmem_pages` we need to have mapped static
memory banks for initialization. Unlike on an MMU system, we cannot map
the entire RAM on an MPU system as we have a limited number of MPU
memory regions. To solve this, transiently map the static memory banks
Hi all,
This series is the third set of patches in the ongoing work to
introduce support for MPU systems and Cortex R82 in Xen.
The patches in this series implement the necessary logic to transiently
map and unmap the static memory banks for initialization.
Cheers,

Introduce helpers (un)map_mm_range() in order to allow the temporary
mapping of a range of memory, and use these to implement the function
`ioremap_attr` for MPU systems.

Implement the MPU variant of `setup_frametable_mappings`. This function
will be called by `setup_mm` when an implementation for MPU systems is
added in a follow up commit.
