There are some generic drivers in the kernel, which make use of the
q-accessors or their derivatives. While at current asm/io.h the accessors
are defined, their implementation is only applicable either for 64bit
systems, or for systems with cpu_has_64bits flag set. Obviously there
are MIPS systems which are neither of these, but still need to have
those drivers supported. In this case the solution is to define some
generic versions of the q-accessors, but with a limitation to be
non-atomic. Such accessors are defined in the
io-64-nonatomic-{hi-lo,lo-hi}.h file. The drivers which utilize the
q-suffixed IO-methods are supposed to include the header file, so
in case if these accessors aren't defined for the platform, the generic
non-atomic versions are utilized. Currently the MIPS-specific asm/io.h
file provides the q-accessors for any MIPS system even for ones, which
in fact don't support them and raise BUG() in case if any of them is
called. Due to this the generic versions of the accessors are never
used while an attempt to call the IO-methods causes the kernel BUG().
In order to fix this we need to define the q-accessors only for
the MIPS systems, which actually support them, and don't define them
otherwise, so to let the corresponding drivers to use the non-atomic
q-suffixed accessors.

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

According to the SDM, for MSR_IA32_PERFCTR0/1 "the lower-order 32 bits of
each MSR may be written with any value, and the high-order 8 bits are
sign-extended according to the value of bit 31", but the fixed counters
in real hardware are limited to the width of the fixed counters ("bits
beyond the width of the fixed-function counter are reserved and must be

After commit:
672ff6cff80c ("KVM: x86: Raise #GP when guest vCPU do not support PMU")
my AMD guests started #GPing like this:
general protection fault: 0000 [#1] PREEMPT SMP
CPU: 1 PID: 4355 Comm: bash Not tainted 5.1.0-rc6+ #3
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014
RIP: 0010:x86_perf_event_update+0x3b/0xa0
with Code: pointing to RDPMC. It is RDPMC because the guest has the
hardware watchdog CONFIG_HARDLOCKUP_DETECTOR_PERF enabled which uses
perf. Instrumenting kvm_pmu_rdpmc() some, showed that it fails due to:
if (!pmu->version)
return 1;
which the above commit added. Since AMD's PMU leaves the version at 0,
that causes the #GP injection into the guest.
Set pmu->version arbitrarily to 1 and move it above the non-applicable
struct kvm_pmu members.

When assigning kvm irqfd we didn't check the irqchip mode but we allow
KVM_IRQFD to succeed with all the irqchip modes. However it does not
make much sense to create irqfd even without the kernel chips. Let's
provide a arch-dependent helper to check whether a specific irqfd is
allowed by the arch. At least for x86, it should make sense to check:
- when irqchip mode is NONE, all irqfds should be disallowed, and,
- when irqchip mode is SPLIT, irqfds that are with resamplefd should
be disallowed.
For either of the case, previously we'll silently ignore the irq or
the irq ack event if the irqchip mode is incorrect. However that can
cause misterious guest behaviors and it can be hard to triage. Let's
fail KVM_IRQFD even earlier to detect these incorrect configurations.

Current logic does not allow VCPU to be loaded onto CPU with
APIC ID 255. This should be allowed since the host physical APIC ID
field in the AVIC Physical APIC table entry is an 8-bit value,
and APIC ID 255 is valid in system with x2APIC enabled.
Instead, do not allow VCPU load if the host APIC ID cannot be
represented by an 8-bit value.
Also, use the more appropriate AVIC_PHYSICAL_ID_ENTRY_HOST_PHYSICAL_ID_MASK
instead of AVIC_MAX_PHYSICAL_ID_COUNT.

Kvm now supports extended CPUID functions through 0x8000001f. CPUID
leaf 0x8000001e is AMD's Processor Topology Information leaf. This
contains similar information to CPUID leaf 0xb (Intel's Extended
Topology Enumeration leaf), and should be included in the output of
KVM_GET_SUPPORTED_CPUID, even though userspace is likely to override
some of this information based upon the configuration of the
particular VM.

description. To gather information for all cache levels, software must
repeatedly execute CPUID with 8000_001Dh in EAX and ECX set to
increasing values beginning with 0 until a value of 00h is returned in
the field CacheType (EAX[4:0]) indicating no more cache descriptions

The termination condition is the same as leaf 4, so we can reuse that

GCC 8.1.0 reports that the ldadd instruction encoding, recently added to
insn.c, doesn't match the mask and couldn't possibly be identified:
linux/arch/arm64/include/asm/insn.h: In function 'aarch64_insn_is_ldadd':
linux/arch/arm64/include/asm/insn.h:280:257: warning: bitwise comparison always evaluates to false [-Wtautological-compare]
Bits [31:30] normally encode the size of the instruction (1 to 8 bytes)
and the current instruction value only encodes the 4- and 8-byte
variants. At the moment only the BPF JIT needs this instruction, and
doesn't require the 1- and 2-byte variants, but to be consistent with
our other ldr and str instruction encodings, clear the size field in the
insn value.

Although we merged support for pseudo-nmi using interrupt priority
masking in 5.1, we've since uncovered a number of non-trivial issues
with the implementation. Although there are patches pending to address
these problems, we're facing issues that prevent us from merging them at
this current time:
https://lkml.kernel.org/r/1556553607-46531-1-git-send-email-julien.thierry@arm.com
For now, simply mark this optional feature as BROKEN in the hope that we
can fix things properly in the near future.

KVM has helpers to handle the condition codes of trapped aarch32
instructions. These are marked __hyp_text and used from HYP, but they
aren't built by the 'hyp' Makefile, which has all the runes to avoid ASAN
and KCOV instrumentation.
Move this code to a new hyp/aarch32.c to avoid a hyp-panic when starting
an aarch32 guest on a host built with the ASAN/KCOV debug options.
Fixes: 021234ef3752f ("KVM: arm64: Make kvm_condition_valid32() accessible from EL2")
