[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH for-next 8/8] x86/domain: move HVM specific code to hvm/domain.c
There is only one function arch_set_info_hvm_guest is moved. The
check_segment function is also moved since arch_set_info_hvm_guest is
the only user.
No functional change.
