Paolo Bonzini 4d526b02df KVM/arm64 updates for 6.16 
* New features:
 
   - Add large stage-2 mapping support for non-protected pKVM guests,
     clawing back some performance.
 
   - Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
     protected modes.
 
   - Enable nested virtualisation support on systems that support it
     (yes, it has been a long time coming), though it is disabled by
     default.
 
 * Improvements, fixes and cleanups:
 
   - Large rework of the way KVM tracks architecture features and links
     them with the effects of control bits. This ensures correctness of
     emulation (the data is automatically extracted from the published
     JSON files), and helps dealing with the evolution of the
     architecture.
 
   - Significant changes to the way pKVM tracks ownership of pages,
     avoiding page table walks by storing the state in the hypervisor's
     vmemmap. This in turn enables the THP support described above.
 
   - New selftest checking the pKVM ownership transition rules
 
   - Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
     even if the host didn't have it.
 
   - Fixes for the address translation emulation, which happened to be
     rather buggy in some specific contexts.
 
   - Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
     from the number of counters exposed to a guest and addressing a
     number of issues in the process.
 
   - Add a new selftest for the SVE host state being corrupted by a
     guest.
 
   - Keep HCR_EL2.xMO set at all times for systems running with the
     kernel at EL2, ensuring that the window for interrupts is slightly
     bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
 
   - Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
     from a pretty bad case of TLB corruption unless accesses to HCR_EL2
     are heavily synchronised.
 
   - Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
     tables in a human-friendly fashion.
 
   - and the usual random cleanups.

/*
* ARM VMSAv8-64 defines an algorithm for finding the translation table
* descriptors in section D4.2.8 in ARM DDI 0487C.a.
*
* The algorithm defines the expectations on the translation table
* addresses for each level, based on PAGE_SIZE, entry level
* and the translation table size (T0SZ). The variable "x" in the
* algorithm determines the alignment of a table base address at a given
* level and thus determines the alignment of VTTBR:BADDR for stage2
* page table entry level.
* Since the number of bits resolved at the entry level could vary
* depending on the T0SZ, the value of "x" is defined based on a
* Magic constant for a given PAGE_SIZE and Entry Level. The
* intermediate levels must be always aligned to the PAGE_SIZE (i.e,
* x = PAGE_SHIFT).
*
* The value of "x" for entry level is calculated as :
* x = Magic_N - T0SZ
*
* where Magic_N is an integer depending on the page size and the entry
* level of the page table as below:
*
* --------------------------------------------
* | Entry level | 4K 16K 64K |
* --------------------------------------------
* | Level: 0 (4 levels) | 28 | - | - |
* --------------------------------------------
* | Level: 1 (3 levels) | 37 | 31 | 25 |
* --------------------------------------------
* | Level: 2 (2 levels) | 46 | 42 | 38 |
* --------------------------------------------
* | Level: 3 (1 level) | - | 53 | 51 |
* --------------------------------------------
*
* We have a magic formula for the Magic_N below:
*
* Magic_N(PAGE_SIZE, Level) = 64 - ((PAGE_SHIFT - 3) * Number_of_levels)
*
* where Number_of_levels = (4 - Level). We are only interested in the
* value for Entry_Level for the stage2 page table.
*
* So, given that T0SZ = (64 - IPA_SHIFT), we can compute 'x' as follows:
*
* x = (64 - ((PAGE_SHIFT - 3) * Number_of_levels)) - (64 - IPA_SHIFT)
* = IPA_SHIFT - ((PAGE_SHIFT - 3) * Number of levels)
*
* Here is one way to explain the Magic Formula:
*
* x = log2(Size_of_Entry_Level_Table)
*
* Since, we can resolve (PAGE_SHIFT - 3) bits at each level, and another
* PAGE_SHIFT bits in the PTE, we have :
*
* Bits_Entry_level = IPA_SHIFT - ((PAGE_SHIFT - 3) * (n - 1) + PAGE_SHIFT)
* = IPA_SHIFT - (PAGE_SHIFT - 3) * n - 3
* where n = number of levels, and since each pointer is 8bytes, we have:
*
* x = Bits_Entry_Level + 3
* = IPA_SHIFT - (PAGE_SHIFT - 3) * n
*
* The only constraint here is that, we have to find the number of page table
* levels for a given IPA size (which we do, see stage2_pt_levels())
