Series x86: Add test cases for LAM | expand

Commit Message

Move struct invpcid_desc to processor.h so that new test cases need
to do invpcid can use the definition.

Opportunistically add packed attribute, because according to C standard,
the allocation of storage unit for bit-field is implementation specific.
