+Subject: [PATCH 2/4] PCI: Don't auto-realloc if we're preserving firmware config
+Origin: https://git.kernel.org/linus/7ac0d094fbe95bf7cc96b3066a97e1090ddc734a
+
+Prevent auto-enabling of bridges reallocation when the FW tells us that the
+initial configuration must be preserved for a given host bridge.
