Subject: [PATCH v11 7/7] x86/sgx: Add check for SGX pages to ghes_do_memory_failure()
Date: Tue, 26 Oct 2021 15:00:50 -0700	[thread overview]
Message-ID: <20211026220050.697075-8-tony.luck@intel.com> (raw)
In-Reply-To: <20211026220050.697075-1-tony.luck@intel.com>

SGX EPC pages do not have a "struct page" associated with them so the
pfn_valid() sanity check fails and results in a warning message to
the console.

Add an additional check to skip the warning if the address of the error
is in an SGX EPC page.
