asm/xen/hypercall.h, asm/xen/hypervisor.h, asm/xen/interface.h and asm/xen/page.h are identical so to avoid code duplication we are just including the original arm header files here. asm/xen/events.h is slightly different, so introduce a different file here (use xchg to implement xchg_xen_ulong and pass regs->pstate to raw_irqs_disabled_flags). Also introduce asm/hypervisor.h and asm/sync_bitops.h. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Ian Campbell <ian.campbell@citrix.com>
