Subject: [PATCH 0/3] efi/memattr: Improve the efi_memattr_init function.

After 8fbe4c49c0ccac ("efi/memattr: Ignore table if the size is clearly
bogus") landed, we are seeing a lot of firmware bugs in the Meta fleet.

There is an indication that this might be related to kexec, but, more on
this later.

While debugging the current issue, I modified the efi_memattr_init()
function in a way that I think it might be useful upstream.

The changes will help to detect EFI problems at scale, by making it more
verbose and easy to categorize early FW bugs.
