Subject: [PATCH] target/i386: csv: Do not register/unregister guest secure
|
||
|
|
memory for CSV3 guest
|
||
|
|
|
||
|
|
CSV3's guest memory is allocated by firmware in secure processor
|
||
|
|
from dedicated memory reserved upon system boot up, consequently
|
||
|
|
it is not necessary to add notifier to pin/unpin memory.
