Minimally rewrite the XArray unit tests to use kunit. This integrates
nicely with existing kunit tools which produce nicer human-readable output
compared to the existing machinery.
Running the xarray tests before this change requires an obscure
invocation
```
tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \
--kconfig_add CONFIG_TEST_XARRAY=y --raw_output=all nothing
```
which on failure produces
```
BUG at check_reserve:513
...
XArray: 6782340 of 6782364 tests passed
```
and exits 0.
Running the xarray tests after this change requires a simpler invocation
```
tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 \
xarray
```
which on failure produces (colors omitted)
```

and exits 1.
Use of richer kunit assertions is intentionally omitted to reduce the
scope of the change.

The recently introduced ROX cache for modules is assuming large page
support in 64-bit mode without testing the related feature bit. This
results in breakage when running as a Xen PV guest, as in this mode large
pages are not supported.
Fix that by testing the X86_FEATURE_PSE capability when deciding whether
to enable the ROX cache.

Pull kvm fixes from Paolo Bonzini:
"The largest part here is for KVM/PPC, where a NULL pointer dereference
was introduced in the 6.13 merge window and is now fixed.
There's some "holiday-induced lateness", as the s390 submaintainer put
it, but otherwise things looks fine.
s390:
- fix a latent bug when the kernel is compiled in debug mode
- two small UCONTROL fixes and their selftests
arm64:
- always check page state in hyp_ack_unshare()
- align set_id_regs selftest with the fact that ASIDBITS field is RO
- various vPMU fixes for bugs that only affect nested virt
PPC e500:
- Fix a mostly impossible (but just wrong) case where IRQs were never
re-enabled
- Observe host permissions instead of mapping readonly host pages as
guest-writable. This fixes a NULL-pointer dereference in 6.13
- Replace brittle VMA-based attempts at building huge shadow TLB
entries with PTE lookups"

For nVHE, switch the filter value in and out if the Coresight driver
asks for it. This will support filters for guests when sinks other than
TRBE are used.
For VHE, just write the filter directly to TRFCR_EL1 where trace can be
used even with TRBE sinks.

Currently in nVHE, KVM has to check if TRBE is enabled on every guest
switch even if it was never used. Because it's a debug feature and is
more likely to not be used than used, give KVM the TRBE buffer status to
allow a much simpler and faster do-nothing path in the hyp.
Protected mode now disables trace regardless of TRBE (because
trfcr_while_in_guest is always 0), which was not previously done.
However, it continues to flush whenever the buffer is enabled
regardless of the filter status. This avoids the hypothetical case of a
host that had disabled the filter but not flushed which would arise if
only doing the flush when the filter was enabled.

Convert TRFCR to automatic generation. Add separate definitions for ELx
and EL2 as TRFCR_EL1 doesn't have CX. This also mirrors the previous
definition so no code change is required.
Also add TRFCR_EL12 which will start to be used in a later commit.
Unfortunately, to avoid breaking the Perf build with duplicate
definition errors, the tools copy of the sysreg.h header needs to be
updated at the same time rather than the usual second commit. This is
because the generated version of sysreg
(arch/arm64/include/generated/asm/sysreg-defs.h), is currently shared
and tools/ does not have its own copy.

* kvm-arm64/pkvm-fixed-features-6.14: (24 commits)
: .
: Complete rework of the pKVM handling of features, catching up
: with the rest of the code deals with it these days.
: Patches courtesy of Fuad Tabba. From the cover letter:
:
: "This patch series uses the vm's feature id registers to track the
: supported features, a framework similar to nested virt to set the
: trap values, and removes the need to store cptr_el2 per vcpu in
: favor of setting its value when traps are activated, as VHE mode
: does."
:
: This branch drags the arm64/for-next/cpufeature branch to solve
: ugly conflicts in -next.

* kvm-arm64/pkvm-np-guest:

: pKVM support for non-protected guests using the standard MM
: infrastructure, courtesy of Quentin Perret. From the cover letter:
:
: "This series moves the stage-2 page-table management of non-protected
: guests to EL2 when pKVM is enabled. This is only intended as an
: incremental step towards a 'feature-complete' pKVM, there is however a
: lot more that needs to come on top.
:
: With that series applied, pKVM provides near-parity with standard KVM
: from a functional perspective all while Linux no longer touches the
: stage-2 page-tables itself at EL1. The majority of mm-related KVM
: features work out of the box, including MMU notifiers, dirty logging,
: RO memslots and things of that nature. There are however two gotchas:
:
: - We don't support mapping devices into guests: this requires
: additional hypervisor support for tracking the 'state' of devices,
: which will come in a later series. No device assignment until then.
:
: - Stage-2 mappings are forced to page-granularity even when backed by a
: huge page for the sake of simplicity of this series. I'm only aiming
: at functional parity-ish (from userspace's PoV) for now, support for
: HP can be added on top later as a perf improvement."

e500 KVM tries to bypass __kvm_faultin_pfn() in order to map VM_PFNMAP
VMAs as huge pages. This is a Bad Idea because VM_PFNMAP VMAs could
become noncontiguous as a result of callsto remap_pfn_range().
Instead, use the already existing host PTE lookup to retrieve a
valid host-side mapping level after __kvm_faultin_pfn() has
returned. Then find the largest size that will satisfy the
guest's request while staying within a single host PTE.

The new __kvm_faultin_pfn() function is upset by the fact that e500 KVM
ignores host page permissions - __kvm_faultin requires a "writable"
outgoing argument, but e500 KVM is nonchalantly passing NULL.
If the host page permissions do not include writability, the shadow
TLB entry is forcibly mapped read-only.

kvmppc_e500_ref_setup is returning whether the guest TLB entry is writable,
which is than passed to kvm_release_faultin_page. This makes little sense
for two reasons: first, because the function sets up the private data for
the page and the return value feels like it has been bolted on the side;
second, because what really matters is whether the _shadow_ TLB entry is
writable. If it is not writable, the page can be released as non-dirty.
Shift from using tlbe_is_writable(gtlbe) to doing the same check on
the shadow TLB entry.

The commit 275f22148e87 ("ipc: rename old-style shmctl/semctl/msgctl
syscalls") switched various architectures to use sys_old_*ctl() with
ipc_parse_version, including mips n32/n64. However, for mips o32, commit
0d6040d46817 ("arch: add split IPC system calls where needed") added
separate IPC syscalls without properly using the old-style handlers.
This causes applications using uClibc-ng to fail with -EINVAL when
calling semctl/shmctl/msgctl with IPC_64 flag, as uClibc-ng uses the
syscall numbers from kernel headers to determine whether to use the IPC
multiplexer or split syscalls. In contrast, glibc is unaffected as it
uses a unified feature test macro __ASSUME_DIRECT_SYSVIPC_SYSCALLS
(disabled for mips-o32) to make this decision.
Fix this by switching the o32 ABI entries for semctl, shmctl and msgctl
to use the old-style handlers, matching the behavior of other
architectures and fixing compatibility with uClibc-ng.

Currently, installation of Debian 12.8 for mipsel fails on machines
without an FPU [1]. This is caused by the fact that zstd (which is used
for initramfs compression) executes the prefx instruction, which is not
emulated properly by the kernel.
The prefx (Prefetch Indexed) instruction fetches data from memory into
the cache without any side effects. Though functionally unrelated, it
requires an FPU [2].
Bytecode format of this instruction ends on "001111" binary:
(prefx instruction format) & 0x0000003f = 0x0000000f
The code in fpux_emu() runs like so:
#define MIPSInst(x) x
#define MIPSInst_FMA_FFMT(x) (MIPSInst(x) & 0x00000007)
#define MIPSInst_FUNC(x) (MIPSInst(x) & 0x0000003f)
enum cop1x_func { ..., pfetch_op = 0x0f, ... };
...
switch (MIPSInst_FMA_FFMT(ir)) {
...
case 0x3:
if (MIPSInst_FUNC(ir) != pfetch_op)
return SIGILL;
/* ignore prefx operation */
break;
default:
return SIGILL;
}
That snippet above contains a logic error and the
if (MIPSInst_FUNC(ir) != pfetch_op)
comparison always fires.
When MIPSInst_FUNC(ir) is equal to pfetch_op, ir must end on 001111
binary. In this case, MIPSInst_FMA_FFMT(ir) must be equal to 0x7, which
does not match that case label.
This causes emulation failure for the prefx instruction. Fix it.
This has been broken by
commit 919af8b96c89 ("MIPS: Make definitions of MIPSInst_FMA_{FUNC,FMTM} consistent with MIPS64 manual")
which modified the MIPSInst_FMA_FFMT macro without updating the users.

This reverts commit 426fa8e4fe7bb914b5977cbce453a9926bf5b2e6.

[3.748895] [drm] Initialized amdgpu ... ...

[1.613326] igb 0000:03:00.0 enp3s0: ... ...
2. More seriously, some workloads (for example, the test
stdlib/test-cxa_atexit2 in the Glibc test suite) triggers an RCU
stall and hang the system with a high probably (4 hangs out of 5
tests).
Revert this commit to use jiffie on Loongson MIPS systems and fix these
issues for now. The root cause may need more investigation.

The Branch Record Buffer Extension (BRBE) adds a number of system
registers and instructions which we don't currently intend to expose to
guests. Our existing logic handles this safely, but this could be
improved with some explicit handling of BRBE.
KVM currently hides BRBE from guests: the cpufeature code's
ftr_id_aa64dfr0[] table doesn't have an entry for the BRBE field, and so
this will be zero in the sanitised value of ID_AA64DFR0 exposed to
guests via read_sanitised_id_aa64dfr0_el1().
KVM currently traps BRBE usage from guests: the default configuration of
the fine-grained trap controls HDFGRTR_EL2.{nBRBDATA,nBRBCTL,nBRBIDR}
and HFGITR_EL2.{nBRBINJ_nBRBIALL} cause these to be trapped to EL2.
Well-behaved guests shouldn't try to use the registers or instructions,
but badly-behaved guests could use these, resulting in unnecessary
warnings from KVM before it injects an UNDEF, e.g.
| kvm [197]: Unsupported guest access at: 401c98
| { Op0( 2), Op1( 1), CRn( 9), CRm( 0), Op2( 0), func_read },
| kvm [197]: Unsupported guest access at: 401d04

| kvm [197]: Unsupported guest access at: 401ff8
| { Op0( 1), Op1( 1), CRn( 7), CRm( 2), Op2( 5), func_write },
As with other features that we know how to handle, these warnings aren't
particularly interesting, and we can simply treat these as UNDEFINED
without any warning. Add the necessary fine-grained undef configuration
to make this happen, as suggested by Marc Zyngier:
https://lore.kernel.org/linux-arm-kernel/86r0czk6wd.wl-maz@kernel.org/
At the same time, update read_sanitised_id_aa64dfr0_el1() to hide BRBE
from guests, as we do for SPE. This will prevent accidentally exposing
BRBE to guests if/when ftr_id_aa64dfr0[] gains a BRBE entry.

There are 2 issues in the code
1. The index is "int" while the address is "unsigned long". This results in
negative value when setting the bitmap.
2. The DMA offset is page shifted but the MMIO range is used as-is (64-bit
address). MMIO address needs to be page shifted as well.

Pull RISC-V fixes from Palmer Dabbelt:
- a handful of selftest fixes
- fix a memory leak in relocation processing during module loading
- avoid sleeping in die()
- fix kprobe instruction slot address calculations
- fix DT node reference leak in SBI idle probing
- avoid initializing out of bounds pages on sparse vmemmap systems with
a gap at the start of their physical memory map
- fix backtracing through exceptions
- _Q_PENDING_LOOPS is now defined whenever QUEUED_SPINLOCKS=y
- local labels in entry.S are now marked with ".L", which prevents them
from trashing backtraces
- a handful of fixes for SBI-based performance counters

For interrupt-map entries, the DTS specification requires
that #address-cells is defined for both the child node and the
interrupt parent. For the PCIe interrupt-map entries, the parent
node ("gic") has not specified #address-cells. The existing layout
of the PCIe interrupt-map entries indicates that it assumes
that #address-cells is zero for this node.
Explicitly set #address-cells to zero for "gic" so that it complies
with the device tree specification.
NVIDIA EDK2 works around this issue by assuming #address-cells
is zero in this scenario, but that workaround is being removed and so
this update is needed or else NVIDIA EDK2 cannot successfully parse the
device tree and the board cannot boot.

The same CXL PMONs support is also avaiable on GNR. Apply
spr_uncore_cxlcm and spr_uncore_cxldp to GNR as well.
The other units were broken on early HW samples, so they were ignored in
the early enabling patch. The issue has been fixed and verified on the
later production HW. Add UPI, B2UPI, B2HOT, PCIEX16 and PCIEX8 for GNR.

The below warning may be triggered on GNR when the PCIE uncore units are
exposed.
WARNING: CPU: 4 PID: 1 at arch/x86/events/intel/uncore.c:1169 uncore_pci_pmu_register+0x158/0x190
The current uncore driver assumes that all the devices in the same PMU
have the exact same devfn. It's true for the previous platforms. But it
doesn't work for the new PCIE uncore units on GNR.
The assumption doesn't make sense. There is no reason to limit the
devices from the same PMU to the same devfn. Also, the current code just
throws the warning, but still registers the device. The WARN_ON_ONCE()
should be removed.
The func_id is used by the later event_init() to check if a event->pmu
has valid devices. For cpu and mmio uncore PMUs, they are always valid.
For pci uncore PMUs, it's set when the PMU is registered. It can be
replaced by the pmu->registered. Clean up the func_id.

Adds a new format for MODVERSIONS which stores each field in a separate
ELF section. This initially adds support for variable length names, but
could later be used to add additional fields to MODVERSIONS in a
backwards compatible way if needed. Any new fields will be ignored by
old user tooling, unlike the current format where user tooling cannot
tolerate adjustments to the format (for example making the name field
longer).
Since PPC munges its version records to strip leading dots, we reproduce
the munging for the new format. Other architectures do not appear to
have architecture-specific usage of this information.

Since commit d492cc2573a0 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the ecard_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.
