[Xen-devel] [PATCH 21/24] xen: drop kexec bits from /sys/hypervisor since kexec isn't implemented yet

[Jeremy Fitzhardinge <jeremy@xxxxxxxx>]

From: Ian Campbell <Ian.Campbell@xxxxxxxxxx>

I needed this to compile since there is no kexec yet in pvops kernel
  CC      drivers/xen/sys-hypervisor.o
drivers/xen/sys-hypervisor.c: In function 'hyper_sysfs_init':
drivers/xen/sys-hypervisor.c:405: error: 'vmcoreinfo_size_xen' undeclared 
(first use in this function)
drivers/xen/sys-hypervisor.c:405: error: (Each undeclared identifier is 
reported only once
drivers/xen/sys-hypervisor.c:405: error: for each function it appears in.)
drivers/xen/sys-hypervisor.c:406: error: implicit declaration of function 
'xen_sysfs_vmcoreinfo_init'
drivers/xen/sys-hypervisor.c: In function 'hyper_sysfs_exit':

(first use in this function)
