Pull kvm fixes from Paolo Bonzini:
"ARM:
- Fix the handling of ZCR_EL2 in NV VMs
- Pick the correct translation regime when doing a PTW on the back of
a SEA
- Prevent userspace from injecting an event into a vcpu that isn't
initialised yet
- Move timer save/restore to the sysreg handling code, fixing EL2
timer access in the process
- Add FGT-based trapping of MDSCR_EL1 to reduce the overhead of debug
- Fix trapping configuration when the host isn't GICv3
- Improve the detection of HCR_EL2.E2H being RES1
- Drop a spurious 'break' statement in the S1 PTW
- Don't try to access SPE when owned by EL3
Documentation updates:
- Document the failure modes of event injection
- Document that a GICv3 guest can be created on a GICv5 host with
FEAT_GCIE_LEGACY
Selftest improvements:
- Add a selftest for the effective value of HCR_EL2.AMO
- Address build warning in the timer selftest when building with
clang
- Teach irqfd selftests about non-x86 architectures
- Add missing sysregs to the set_id_regs selftest
- Fix vcpu allocation in the vgic_lpi_stress selftest
- Correctly enable interrupts in the vgic_lpi_stress selftest
x86:
- Expand the KVM_PRE_FAULT_MEMORY selftest to add a regression test
for the bug fixed by commit 3ccbf6f47098 ("KVM: x86/mmu: Return
-EAGAIN if userspace deletes/moves memslot during prefault")
- Don't try to get PMU capabilities from perf when running a CPU with
hybrid CPUs/PMUs, as perf will rightly WARN.
guest_memfd:
- Rework KVM_CAP_GUEST_MEMFD_MMAP (newly introduced in 6.18) into a
more generic KVM_CAP_GUEST_MEMFD_FLAGS
- Add a guest_memfd INIT_SHARED flag and require userspace to
explicitly set said flag to initialize memory as SHARED,
irrespective of MMAP.
The behavior merged in 6.18 is that enabling mmap() implicitly
initializes memory as SHARED, which would result in an ABI
collision for x86 CoCo VMs as their memory is currently always
initialized PRIVATE.
- Allow mmap() on guest_memfd for x86 CoCo VMs, i.e. on VMs with
private memory, to enable testing such setups, i.e. to hopefully
flush out any other lurking ABI issues before 6.18 is officially
released.
- Add testcases to the guest_memfd selftest to cover guest_memfd
without MMAP, and host userspace accesses to mmap()'d private
memory"

This fixes the following build error
CLNG-BPF [test_progs] verifier_global_ptr_args.bpf.o
progs/verifier_global_ptr_args.c:228:5: error: redefinition of 'off' as
different kind of symbol
228 | u32 off;
| ^
The symbol 'off' was previously defined in
tools/testing/selftests/bpf/tools/include/vmlinux.h, which includes an
enum i40e_ptp_gpio_pin_state from
drivers/net/ethernet/intel/i40e/i40e_ptp.c:
enum i40e_ptp_gpio_pin_state {
end = -2,
invalid = -1,
off = 0,
in_A = 1,
in_B = 2,
out_A = 3,
out_B = 4,
};
This enum is included when CONFIG_I40E is enabled. As of commit
032676ff8217 ("LoongArch: Update Loongson-3 default config file"),
CONFIG_I40E is set in the defconfig, which leads to the conflict.
Renaming the local variable avoids the redefinition and allows the
build to succeed.

test_parse_test_list_file writes some data to
/tmp/bpf_arg_parsing_test.XXXXXX and parse_test_list_file() will read
the data back. However, after writing data to that file, we forget to
call fsync() and it's causing testing failure in my laptop. This patch
helps fix it by adding the missing fsync() call.
