Add the basic infrastructure needed to test AMD nested SVM.
This is largely copied from the KVM unit test infrastructure.

<title>selftests, kvm: Replace manual MSR defs with common msr-index.h</title>

<id>a5543d3456dd131f072c5c278f1708aeaeaff0da</id>
<content type='text'>
The kernel's version of msr-index.h was pulled wholesale into tools by
commit

  444e2ff34df8 ("tools arch x86: Grab a copy of the file containing the MSR numbers"),

Use the common msr-index.h instead of manually redefining everything in
a KVM-only header.

Note, a few MSR-related definitions remain in processor.h because they
are not covered by msr-index.h, including the awesomely named
APIC_BASE_MSR, which refers to starting index of the x2APIC MSRs, not
the actual MSR_IA32_APICBASE, which *is* defined by msr-index.h.

Fix the following build error from "make TARGETS=kvm kselftest":

libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC

This error is seen when build is done from the main Makefile using
kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
are defined.

When build is invoked using:

"make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
aren't defined.

There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the
check to determine if --no-pie is necessary, which is the case when these
two aren't defined when "make -C tools/testing/selftests/kvm" runs.

Fix it by simplifying the no-pie-option logic. With this change, both
build variations work.

Check that accesses by nested guests are logged according to the
L1 physical addresses rather than L2.

Most of the patch is really adding EPT support to the testing
framework.

<content type='text'>
To run the dirty_log_test on s390x, we have to make sure that we
access the dirty log bitmap with little endian byte ordering and
we have to properly align the memslot of the guest.
Also all dirty bits of a segment are set once on s390x when one
of the pages of a segment are written to for the first time, so
we have to make sure that we touch all pages during the first
iteration to keep the test in sync here.
DEFAULT_GUEST_TEST_MEM needs an adjustment, too. On some s390x
distributions, the ELF binary is linked to address 0x80000000,
so we have to avoid that our test region overlaps into this area.
0xc0000000 seems to be a good alternative that should work on x86
and aarch64, too.
