The hardware denies any access from the Linux non-secure world to the
secure-protected pins. Hence, prevent any driver to request such a pin.

Mark the secure-protected GPIO lines as invalid (.init_valid_mask) and
prevent the pinmux request / pinconf setting operations.
Identify the secure pins with "NO ACCESS" in the pinconf sysfs.

KVM: x86: work around QEMU issue with synthetic CPUID leaves

Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU,
which assumes the *host* CPUID[0x80000000].EAX is higher or equal
to what KVM_GET_SUPPORTED_CPUID reports.

This causes QEMU to issue bogus host CPUIDs when preparing the input
to KVM_SET_CPUID2.  It can even get into an infinite loop, which is
only terminated by an abort():

   cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e)

To work around this, only synthesize those leaves if 0x8000001d exists
on the host.  The synthetic 0x80000021 leaf is mostly useful on Zen2,
which satisfies the condition.

non-init mm is inherently dangerous and flawed, as the only reason to use
an mm other than init_mm is to walk a userspace mapping, and
lookup_address_in_pgd() does not play nice with userspace mappings, e.g.
doesn't disable IRQs to block TLB shootdowns and doesn't use READ_ONCE()
to ensure an upper level entry isn't converted to a huge page between
checking the PAGE_SIZE bit and grabbing the address of the next level
down.

This reverts commit 13c72c060f1ba6f4eddd7b1c4f52a8aded43d6d9.

KVM: x86/mmu: fix potential races when walking host page table

KVM uses lookup_address_in_mm() to detect the hugepage size that the host
uses to map a pfn.  The function suffers from several issues:

 - no usage of READ_ONCE(*). This allows multiple dereference of the same
   page table entry. The TOCTOU problem because of that may cause KVM to
   incorrectly treat a newly generated leaf entry as a nonleaf one, and
   dereference the content by using its pfn value.

 - the information returned does not match what KVM needs; for non-present
   entries it returns the level at which the walk was terminated, as long
   as the entry is not 'none'.  KVM needs level information of only 'present'
   entries, otherwise it may regard a non-present PXE entry as a present
   large page mapping.

 - the function is not safe for mappings that can be torn down, because it
   does not disable IRQs and because it returns a PTE pointer which is never
   safe to dereference after the function returns.

So implement the logic for walking host page tables directly in KVM, and
stop using lookup_address_in_mm().

KVM: fix bad user ABI for KVM_EXIT_SYSTEM_EVENT

When KVM_EXIT_SYSTEM_EVENT was introduced, it included a flags
member that at the time was unused.  Unfortunately this extensibility
mechanism has several issues:

- x86 is not writing the member, so it would not be possible to use it
  on x86 except for new events

- the member is not aligned to 64 bits, so the definition of the
  uAPI struct is incorrect for 32- on 64-bit userspace.  This is a
  problem for RISC-V, which supports CONFIG_KVM_COMPAT, but fortunately
  usage of flags was only introduced in 5.18.

Since padding has to be introduced, place a new field in there
that tells if the flags field is valid.  To allow further extensibility,
in fact, change flags to an array of 16 values, and store how many
of the values are valid.  The availability of the new ndata field
is tied to a system capability; all architectures are changed to
fill in the field.

To avoid breaking compilation of userspace that was using the flags
field, provide a userspace-only union to overlap flags with data[0].
The new field is placed at the same offset for both 32- and 64-bit
userspace.

On bare metal, encountering an impossible gpa in the page fault path is
well and truly impossible, barring CPU bugs, as the CPU will signal #PF
during the gva=>gpa translation (or a similar failure when stuffing a
physical address into e.g. the VMCS/VMCB).  But if KVM is running as a VM
itself, the MAXPHYADDR enumerated to KVM may not be the actual MAXPHYADDR
of the underlying hardware, in which case the hardware will not fault on
the illegal-from-KVM's-perspective gpa.

Alternatively, KVM could continue allowing the dodgy behavior and simply
zap the max possible range.  But, for hosts with MAXPHYADDR < 52, that's
a (minor) waste of cycles, and more importantly, KVM can't reasonably
support impossible memslots when running on bare metal (or with an
accurate MAXPHYADDR as a VM).  Note, limiting the overhead by checking if
KVM is running as a guest is not a safe option as the host isn't required
to announce itself to the guest in any way, e.g. doesn't need to set the
HYPERVISOR CPUID bit.

A second alternative to disallowing the memslot behavior would be to
disallow creating a VM with guest.MAXPHYADDR > host.MAXPHYADDR.  That
restriction is undesirable as there are legitimate use cases for doing
so, e.g. using the highest host.MAXPHYADDR out of a pool of heterogeneous
systems so that VMs can be migrated between hosts with different
MAXPHYADDRs without running afoul of the allow_smaller_maxphyaddr mess.

Note that any guest.MAXPHYADDR is valid with shadow paging, and it is
even useful in order to test KVM with MAXPHYADDR=52 (i.e. without
any reserved physical address bits).

The now common kvm_mmu_max_gfn() is inclusive instead of exclusive.
The memslot and TDP MMU code want an exclusive value, but the name
implies the returned value is inclusive, and the MMIO path needs an
inclusive check.
