Date: Thu,  1 Apr 2021 15:20:28 -0400	[thread overview]
Message-ID: <20210401192033.91150-1-krish.sadhukhan@oracle.com> (raw)

v4 -> v5:
        1. In patch# 1, the actual size of the MSRPM and IOPM tables are now
	   defined. The initialization code for the tables has been adjusted
	   accordingly.
	2. In patch# 2, the checks have been adjusted based on the actual
	   size of the tables. The check for IOPM has also been fixed.
	3. In patch# 4, a new test case has been added. This new test uses
	   an address whose last byte touched the limit of the maximum
	   physical address.
