Rework the CPU selection in the migration worker to ensure the specified
number of migrations are performed when the test iteslf is affined to a
subset of CPUs. The existing logic skips iterations if the target CPU is
not in the original set of possible CPUs, which causes the test to fail
if too many iterations are skipped.

Only performed 4 KVM_RUNs, task stalled too much?
Calculate the min/max possible CPUs as a cheap "best effort" to avoid
high runtimes when the test is affined to a small percentage of CPUs.
Alternatively, a list or xarray of the possible CPUs could be used, but
even in a horrendously inefficient setup, such optimizations are not
needed because the runtime is completely dominated by the cost of
migrating the task, and the absolute runtime is well under a minute in
even truly absurd setups, e.g. running on a subset of vCPUs in a VM that
is heavily overcommited (16 vCPUs per pCPU).

When building bpf selftest with make -j, I'm randomly getting build failures
such as this one:
In file included from progs/bpf_flow.c:19:
[...]/tools/testing/selftests/bpf/tools/include/bpf/bpf_helpers.h:11:10: fatal error: 'bpf_helper_defs.h' file not found
#include "bpf_helper_defs.h"
^~~~~~~~~~~~~~~~~~~
The file that fails the build varies between runs but it's always in the
progs/ subdir.
The reason is a missing make dependency on libbpf for the .o files in
progs/. There was a dependency before commit 3ac2e20fba but that commit
removed it to prevent unneeded rebuilds. However, that only works if libbpf
has been built already; the 'wildcard' prerequisite does not trigger when
there's no bpf_helper_defs.h generated yet.
Keep the libbpf as an order-only prerequisite to satisfy both goals. It is
always built before the progs/ objects but it does not trigger unnecessary
rebuilds by itself.

Pull arm64 fixes from Catalin Marinas:
- It turns out that the optimised string routines merged in 5.14 are
not safe with in-kernel MTE (KASAN_HW_TAGS) because of reading beyond
the end of a string (strcmp, strncmp). Such reading may go across a
16 byte tag granule and cause a tag check fault. When KASAN_HW_TAGS
is enabled, use the generic strcmp/strncmp C implementation.
- An errata workaround for ThunderX relied on the CPU capabilities
being enabled in a specific order. This disappeared with the
automatic generation of the cpucaps.h file (sorted alphabetically).
Fix it by checking the current CPU only rather than the system-wide
capability.
- Add system_supports_mte() checks on the kernel entry/exit path and
thread switching to avoid unnecessary barriers and function calls on
systems where MTE is not supported.
- kselftests: skip arm64 tests if the required features are missing.

Compiling the KVM selftests with clang emits the following warning:

>> return (unsigned long)xmm0;
where xmm0 is accessed via an uninitialized register variable.
Indeed, this is a misuse of register variables, which really should only
be used for specifying register constraints on variables passed to
inline assembly. Rather than attempting to read xmm registers via
register variables, just explicitly perform the movq from the desired
xmm register.

While x86 does not require any additional setup to use the ucall

resulting in the test spinning indefinitely.

Test that if:
* L1 disables virtual interrupt masking, and INTR intercept.
* L1 setups a virtual interrupt to be injected to L2 and enters L2 with
interrupts disabled, thus the virtual interrupt is pending.
* Now an external interrupt arrives in L1 and since
L1 doesn't intercept it, it should be delivered to L2 when
it enables interrupts.
to do this L0 (abuses) V_IRQ to setup an
interrupt window, and returns to L2.
* L2 enables interrupts.
This should trigger the interrupt window,
injection of the external interrupt and delivery
of the virtual interrupt that can now be done.
* Test that now L2 gets those interrupts.
This is the test that demonstrates the issue that was
fixed in the previous patch.

All selftests that support the backing_src option were printing their
own description of the flag and then calling backing_src_help() to dump
the list of available backing sources. Consolidate the flag printing in
backing_src_help() to align indentation, reduce duplicated strings, and
improve consistency across tests.
Note: Passing "-s" to backing_src_help is unnecessary since every test
uses the same flag. However I decided to keep it for code readability
at the call sites.
While here this opportunistically fixes the incorrectly interleaved
printing -x help message and list of backing source types in
dirty_log_perf_test.

The SMC64 calling convention passes a function identifier in w0 and its
parameters in x1-x17. Given this, there are two deviations in the
SMC64 call performed by the steal_time test: the function identifier is
assigned to a 64 bit register and the parameter is only 32 bits wide.
Align the call with the SMCCC by using a 32 bit register to handle the
