KVM: selftests: page_table_test: fix calculation of guest_test_phys_mem
A kvm_page_table_test run with its default settings fails on VMX due to memory region add failure: > ==== Test Assertion Failure ==== > lib/kvm_util.c:952: ret == 0 > pid=10538 tid=10538 errno=17 - File exists > 1 0x00000000004057d1: vm_userspace_mem_region_add at kvm_util.c:947 > 2 0x0000000000401ee9: pre_init_before_test at kvm_page_table_test.c:302 > 3 (inlined by) run_test at kvm_page_table_test.c:374 > 4 0x0000000000409754: for_each_guest_mode at guest_modes.c:53 > 5 0x0000000000401860: main at kvm_page_table_test.c:500 > 6 0x00007f82ae2d8554: ?? ??:0 > 7 0x0000000000401894: _start at ??:? > KVM_SET_USER_MEMORY_REGION IOCTL failed, > rc: -1 errno: 17 > slot: 1 flags: 0x0 > guest_phys_addr: 0xc0000000 size: 0x40000000 This is because the memory range that this test is trying to add (0x0c0000000 - 0x100000000) conflicts with LAPIC mapping at 0x0fee00000. Looking at the code it seems that guest_test_*phys*_mem variable gets mistakenly overwritten with guest_test_*virt*_mem while trying to adjust the former for alignment. With the correct variable adjusted this test runs successfully. Signed-off-by:Maciej S.
