[Xen-devel] [PATCH] fix QEMU build on Xen/ARM

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

xen_get_vmport_regs_pfn should take a xen_pfn_t argument, not an
unsigned long argument (in fact xen_pfn_t is defined as uint64_t on
ARM).

Also use xc_hvm_param_get instead of the deprecated xc_get_hvm_param.
