[ Upstream commit e0d335077831196bffe6a634ffe385fc684192ca ]
There are no "struct page" associations with SGX pages, causing the check pfn_to_online_page() to fail. This results in the inability to decode the SGX addresses and warning messages like:
Invalid address 0x34cc9a98840 in IA32_MC17_ADDR
Add an additional check to allow the decoding of the error address and to skip the warning message, if the error address is an SGX address.
