X-Git-Tag: firefly_0821_release~3680^2~4456^2~11
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c00c8aa2d976e9ed1d12a57b42d6e9b27efb7abe;p=firefly-linux-kernel-4.4.55.git

xen/trace: Fix compile error when CONFIG_XEN_PRIVILEGED_GUEST is not set

with CONFIG_XEN and CONFIG_FTRACE set we get this:

arch/x86/xen/trace.c:22: error: ‘__HYPERVISOR_console_io’ undeclared here (not in a function)
arch/x86/xen/trace.c:22: error: array index in initializer not of integer type
arch/x86/xen/trace.c:22: error: (near initialization for ‘xen_hypercall_names’)
arch/x86/xen/trace.c:23: error: ‘__HYPERVISOR_physdev_op_compat’ undeclared here (not in a function)

Issue was that the definitions of __HYPERVISOR were not pulled
if CONFIG_XEN_PRIVILEGED_GUEST was not set.
