added a test test_core_btfgen to test core relocation with btf
generated with 'bpftool gen min_core_btf'. Currently,

Alexei found that in the above core_reloc_btfgen/enum64val___err_missing
should not be skipped.
Currently, the core_reloc tests have some negative tests.
In Commit 704c91e59f, for core_reloc_btfgen, all negative tests
are skipped with the following condition
if (!test_case->btf_src_file || test_case->fails) {
test__skip();
continue;
}
This is too conservative. Negative tests do not fail
mkstemp() and run_btfgen() should not be skipped.
There are a few negative tests indeed failing run_btfgen()
and this patch added 'run_btfgen_fails' to mark these tests
so that they can be skipped for btfgen tests. With this,

Unlike GCC clang uses a single compiler image to support multiple target
architectures meaning that we can't simply rely on CROSS_COMPILE to select
the output architecture. Instead we must pass --target to the compiler to
tell it what to output, kselftest was not doing this so cross compilation
of kselftest using clang resulted in kselftest being built for the host
architecture.
More work is required to fix tests using custom rules but this gets the
bulk of things building.

Pull kvm fixes from Paolo Bonzini:
"While last week's pull request contained miscellaneous fixes for x86,
this one covers other architectures, selftests changes, and a bigger
series for APIC virtualization bugs that were discovered during 5.20
development. The idea is to base 5.20 development for KVM on top of
this tag.
ARM64:
- Properly reset the SVE/SME flags on vcpu load
- Fix a vgic-v2 regression regarding accessing the pending state of a
HW interrupt from userspace (and make the code common with vgic-v3)
- Fix access to the idreg range for protected guests
- Ignore 'kvm-arm.mode=protected' when using VHE
- Return an error from kvm_arch_init_vm() on allocation failure
- A bunch of small cleanups (comments, annotations, indentation)
RISC-V:
- Typo fix in arch/riscv/kvm/vmid.c
- Remove broken reference pattern from MAINTAINERS entry
x86-64:
- Fix error in page tables with MKTME enabled
- Dirty page tracking performance test extended to running a nested
guest
- Disable APICv/AVIC in cases that it cannot implement correctly"

Pull random number generator fixes from Jason Donenfeld:
- A fix for a 5.19 regression for a case in which early device tree
initializes the RNG, which flips a static branch.
On most plaforms, jump labels aren't initialized until much later, so
this caused splats. On a few mailing list threads, we cooked up easy
fixes for arm64, arm32, and risc-v. But then things looked slightly
more involved for xtensa, powerpc, arc, and mips. And at that point,
when we're patching 7 architectures in a place before the console is
even available, it seems like the cost/risk just wasn't worth it.
So random.c works around it now by checking the already exported
`static_key_initialized` boolean, as though somebody already ran into
this issue in the past. I'm not super jazzed about that; it'd be
prettier to not have to complicate downstream code. But I suppose
it's practical.
- A few small code nits and adding a missing __init annotation.
- A change to the default config values to use the cpu and bootloader's
seeds for initializing the RNG earlier.
This brings them into line with what all the distros do (Fedora/RHEL,
Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
least), and moreover will now give us test coverage in various test
beds that might have caught the above device tree bug earlier.
- A change to WireGuard CI's configuration to increase test coverage
around the RNG.
- A documentation comment fix to unrelated maintainerless CRC code that
I was asked to take, I guess because it has to do with polynomials
(which the RNG thankfully no longer uses).

Add a static assert to the KVM/VM/vCPU ioctl() helpers to verify that the
size of the argument provided matches the expected size of the IOCTL.
Because ioctl() ultimately takes a "void *", it's all too easy to pass in
garbage and not detect the error until runtime. E.g. while working on a
CPUID rework, selftests happily compiled when vcpu_set_cpuid()
unintentionally passed the cpuid() function as the parameter to ioctl()
(a local "cpuid" parameter was removed, but its use was not replaced with
"vcpu->cpuid" as intended).
Tweak a variety of benign issues that aren't compatible with the sanity
check, e.g. passing a non-pointer for ioctls().
Note, static_assert() requires a string on older versions of GCC. Feed
it an empty string to make the compiler happy.

Add kvm_has_cap() to wrap kvm_check_cap() and return a bool for the use
cases where the caller only wants check if a capability is supported,
i.e. doesn't care about the value beyond whether or not it's non-zero.
The "check" terminology is somewhat ambiguous as the non-boolean return
suggests that '0' might mean "success", i.e. suggests that the ioctl uses
the 0/-errno pattern. Provide a wrapper instead of trying to find a new
name for the raw helper; the "check" terminology is derived from the name
of the ioctl, so using e.g. "get" isn't a clear win.

Handle all memslot0 size adjustments in __vm_create(). Currently, the

call vm_create() or __vm_create() directly are left to their own devices.
Some tests just pass DEFAULT_GUEST_PHY_PAGES and don't bother with any
adjustments, while others mimic the per-vCPU calculations.
For vm_create(), and thus __vm_create(), take the number of vCPUs that
will be runnable to calculate that number of per-vCPU pages needed for
memslot0. To give readers a hint that neither vm_create() nor
__vm_create() create vCPUs, name the parameter @nr_runnable_vcpus instead
of @nr_vcpus. That also gives readers a hint as to why tests that create
larger numbers of vCPUs but never actually run those vCPUs can skip
