I never had much luck running mm selftests so I spent a few hours
digging into why.
Looks like most of the reason is missing SKIP checks, so this series is
just adding a bunch of those that I found. I did not do anything like
all of them, just the ones I spotted in gup_longterm, gup_test, mmap,

It's pretty obvious that the test wouldn't work if you don't have the
feature enabled. But, it's still useful to SKIP instead of failing so
the reader can immediately tell that this is the reason why.

Add GHCB call to register Secure AVIC guest APIC backing page
GPA with the hyperversior. This call ensures that guest APIC
backing page is pinned in NPT while vCPU is running.

Add provision to pass custom args to kvm_arch_vm_post_create().
This will be used to pass sev init args (vmsa features) for SEV VMs.

Add a test_kfree_rcu_wq_destroy test to verify a kmem_cache_destroy()
from a workqueue context. The problem is that, before destroying any
cache the kvfree_rcu_barrier() is invoked to guarantee that in-flight
freed objects are flushed.
The _barrier() function queues and flushes its own internal wo
Currently kvfree_rcu() APIs use a system workqueue which is
"system_unbound_wq" to driver RCU machinery to reclaim a memory.
Recently, it has been noted that the following kernel warning can
be observed:
workqueue: WQ_MEM_RECLAIM nvme-wq:nvme_scan_work is flushing !WQ_MEM_RECLAIM

Add idle halt entry and exit on pending events test for
Secure AVIC guests. Secure AVIC guests require idle halt
intercept to be enabled. Without idle halt intercept being
enabled, guest can block in halt forever as hv does not
have access to APIC_IRR state to check for pending events.

Extend SAVIC test with various NMI tests:
- Test NMI injection failure when AllowedNMI is not set
by guest.
- Test NMI injection when 2 NMIs are pending.
- Test ICR based cross-VCPU NMI for fixed-phys, fixed-logical,
broadcast-all and broadcast-exclself modes.

Add a APIC regs to verify APIC register updates at various
stages in Secure AVIC guest's APIC enablement. In summary,
do below validations:
- Verify that the initial reset of APIC is xapic.
- Values written by SAVIC guest in xapic mode are propagated
to host APIC state.
- APIC regs state updates
