The current code in pv_domain_initialise() populates the L3 slot used for the GDT/LDT, however that's not needed, since the create_perdomain_mapping() in pv_create_gdt_ldt_l1tab() will already take care of allocating an L2 and populating the L3 entry if not present. No functional change intended. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com> --- xen/arch/x86/pv/domain.c | 6 ------ 1 file changed, 6 deletions(-)
