[PULL 4/5] numa: avoid crash with SGX and "info numa"


From: Paolo Bonzini
Subject: [PULL 4/5] numa: avoid crash with SGX and "info numa"
Date: Thu, 11 Nov 2021 08:36:06 +0100

Add the MEMORY_DEVICE_INFO_KIND_SGX_EPC case, so that enclave
memory is included in the output of "info numa" instead of crashing
the monitor.

Fixes: a7c565a941 ("sgx-epc: Add the fill_device_info() callback support", 
2021-09-30)
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
