[coreboot-gerrit] Change in coreboot[master]: cpu/x86/smm: Check that the stub size is < save state size

[Arthur Heymans (Code Review)]

Hello build bot (Jenkins), Angel Pons, Aaron Durbin,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/47069

to look at the new patch set (#2).

Change subject: cpu/x86/smm: Check that the stub size is < save state size

cpu/x86/smm: Check that the stub size is < save state size

If the stub size would be larger than the save state size, the stagger
points would overlap with the stub.

The check is placed in the stub placement code. The stub placement
code is called twice. Once for the initial SMM relocatation and for
the permanent handler in TSEG. So the check is done twice, which is
not really needed.
