Add a refcount to struct io_zcrx_ifq to reverse the refcounting
relationship i.e. rings now reference ifqs instead. As a result of this,
remove ctx->refs that an ifq holds on a ring via the page pool memory
provider.
This ref ifq->refs is held by internal users of an ifq, namely rings and
the page pool memory provider associated with an ifq. This is needed to
keep the ifq around until the page pool is destroyed.
Since ifqs now no longer hold refs to ring ctx, there isn't a need to
split the cleanup of ifqs into two: io_shutdown_zcrx_ifqs() in
io_ring_exit_work() while waiting for ctx->refs to drop to 0, and
io_unregister_zcrx_ifqs() after. Remove io_shutdown_zcrx_ifqs().

In the ifq cleanup path, these are the only fields used from the main

io_uring task work dispatch makes an indirect call to struct io_kiocb's
io_task_work.func field to allow running arbitrary task work functions.
In the uring_cmd case, this calls io_uring_cmd_work(), which immediately
makes another indirect call to struct io_uring_cmd's task_work_cb field.
Change the uring_cmd task work callbacks to functions whose signatures
match io_req_tw_func_t. Add a function io_uring_cmd_from_tw() to convert
from the task work's struct io_tw_req argument to struct io_uring_cmd *.
Define a constant IO_URING_CMD_TASK_WORK_ISSUE_FLAGS to avoid
manufacturing issue_flags in the uring_cmd task work callbacks. Now
uring_cmd task work dispatch makes a single indirect call to the
uring_cmd implementation's callback. This also allows removing the
task_work_cb field from struct io_uring_cmd, freeing up 8 bytes for
future storage.
Since fuse_uring_send_in_task() now has access to the io_tw_token_t,
check its cancel field directly instead of relying on the
IO_URING_F_TASK_DEAD issue flag.

Normal rings support 64b SQEs for posting submissions, while certain
features require the ring to be configured with IORING_SETUP_SQE128, as
they need to convey more information per submission. This, in turn,
makes ALL the SQEs be 128b in size. This is somewhat wasteful and
inefficient, particularly when only certain SQEs need to be of the
bigger variant.
This adds support for setting up a ring with mixed SQE sizes, using
IORING_SETUP_SQE_MIXED. When setup in this mode, SQEs posted to the ring
may be either 64b or 128b in size. If a SQE is 128b in size, then opcode
will be set to a variante to indicate that this is the case. Any other
non-128b opcode will assume the SQ's default size.
SQEs on these types of mixed rings may also utilize NOP with skip
success set. This can happen if the ring is one (small) SQE entry away
from wrapping, and an attempt is made to get a 128b SQE. As SQEs must be
contiguous in the SQ ring, a 128b SQE cannot wrap the ring. For this
case, a single NOP SQE should be inserted with the SKIP_SUCCESS flag
set. The kernel will process this as a normal NOP and without posting a
CQE.

Rather than do per-tw checking, which needs to dip into the task_struct
for checking flags, do it upfront before running task_work. This places
a 'cancel' member in io_tw_token_t, which is assigned before running
task_work for that given ctx.
This is both more efficient in doing it upfront rather than for every
task_work, and it means that io_should_terminate_tw() can be made
private in io_uring.c rather than need to be called by various
callbacks of task_work.

- 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 3ccbf6f470 ("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.
