Subject: [PATCH] xen/pci: gate APEI support on ARM
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

APEI not supported on ARM yet move the code under CONFIG_X86 flag to
gate the code for ARM.

This patch is the preparatory work to enable HAS_PCI on ARM to avoid
compilation error on ARM.

prelink.o: In function `pcie_aer_get_firmware_first’:
drivers/passthrough/pci.c:1251: undefined reference to `apei_hest_parse'
