[Xen-devel] [PATCH] x86: move hvm_domain_use_pirq to hvm files

After applying all my patches for CONFIG_HVM series, I got this from a
shim build:

$ nm xen-shim-syms | grep -i hvm
ffff82d080260550 T hvm_domain_use_pirq
ffff82d080369520 D hvm_max_cpuid_policy
ffff82d08036b95c D hvm_max_msr_policy
ffff82d08036b950 D hvm_max_vcpu_msrs
ffff82d0802cc440 T HYPERCALL_hvm_op
ffff82d080363116 t opt_msr_sc_hvm
ffff82d080363114 t opt_rsb_hvm

It seems hvm_domain_use_pirq is the only one that worth touching.
