This driver supports page faults on PCI RID since commit <9f831c16c69e>
("iommu/vt-d: Remove the pasid present check in prq_event_thread") by
allowing the reporting of page faults with the pasid_present field cleared
to the upper layer for further handling. The fundamental assumption here
is that the detach or replace operations act as a fence for page faults.
This implies that all pending page faults associated with a specific RID
or PASID are flushed when a domain is detached or replaced from a device
RID or PASID.
However, the intel_iommu_drain_pasid_prq() helper does not correctly
handle faults for RID. This leads to faults potentially remaining pending
in the iommu hardware queue even after the domain is detached, thereby
violating the aforementioned assumption.
Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults
for RID.
Fixes: 9f831c16c69e ("iommu/vt-d: Remove the pasid present check in prq_event_thread")

This is because in resume path, CNTRL[EPHEn] is not set. Fix this by
setting CNTRL[EPHEn] to 1 in resume path if EFR[EPHSUP] is set.
Note
May be better approach is to save the control register in suspend path
and restore it in resume path instead of trying to set indivisual
bits. We will have separate patch for that.

On HCI_OP_RESET command, firmware raises alive interrupt. Driver needs
to wait for this before sending other command. This patch fixes the potential
miss of alive interrupt due to which HCI_OP_RESET can timeout.
Expected flow:
If tx command is HCI_OP_RESET,
1. set data->gp0_received = false
2. send HCI_OP_RESET
3. wait for alive interrupt
Actual flow having potential race:
If tx command is HCI_OP_RESET,
1. send HCI_OP_RESET
1a. Firmware raises alive interrupt here and in ISR
data->gp0_received is set to true
2. set data->gp0_received = false

Today a PV guest (including dom0) can create 2MB contiguous memory
regions for DMA buffers at max. This has led to problems at least
with the megaraid_sas driver, which wants to allocate a 2.3MB DMA
buffer.
The limiting factor is the frame array used to do the hypercall for
making the memory contiguous, which has 512 entries and is just a
static array in mmu_pv.c.
In order to not waste memory for non-PV guests, put the initial
frame array into .init.data section and dynamically allocate an array
from the .init_after_bootmem hook of PV guests.
In case a contiguous memory area larger than the initially supported
2MB is requested, allocate a larger buffer for the frame list. Note
that such an allocation is tried only after memory management has been
initialized properly, which is tested via a flag being set in the
.init_after_bootmem hook.

When mapping a buffer for DMA via .map_page or .map_sg DMA operations,
there is no need to check the machine frames to be aligned according
to the mapped areas size. All what is needed in these cases is that the
buffer is contiguous at machine level.
So carve out the alignment check from range_straddles_page_boundary()
and move it to a helper called by xen_swiotlb_alloc_coherent() and
xen_swiotlb_free_coherent() directly.

Starting with Rust 1.85.0 (to be released 2025-02-20), `rustc` warns
[1] about disabling neon in the aarch64 hardfloat target:
warning: target feature `neon` cannot be toggled with
`-Ctarget-feature`: unsound on hard-float targets
because it changes float ABI
|
= note: this was previously accepted by the compiler but
is being phased out; it will become a hard error
in a future release!
= note: for more information, see issue #116344
<https://github.com/rust-lang/rust/issues/116344>
Thus, instead, use the softfloat target instead.
While trying it out, I found that the kernel sanitizers were not enabled
for that built-in target [2]. Upstream Rust agreed to backport
the enablement for the current beta so that it is ready for
the 1.85.0 release [3] -- thanks!
However, that still means that before Rust 1.85.0, we cannot switch
since sanitizers could be in use. Thus conditionally do so.

Perhaps unsurprisingly there are some platforms where the GTDT isn't
quite right and the Platforms Timer array overflows the length of the
overall table.
While the recently-added sanity checking isn't wrong, it makes it
impossible to boot the kernel on offending platforms. Try to hobble
along and limit the Platform Timer count to the bounds of the table.

a soft spot with theoretical risk of UAF for CPUMASK_OFFSTACK cases.
To make things sound, delay allocating said cpumask

For XDP transmit case, swdata doesn't contain SKB but the
XDP Frame. Infer the correct swdata based on buffer type
and return the XDP Frame for XDP transmit case.

For successful XDP_TX and XDP_REDIRECT cases, the packet was received
successfully so update RX statistics. Use original received
packet length for that.
TX packets statistics are incremented on TX completion so don't
update it while TX queueing.
If xdp_convert_buff_to_frame() fails, increment tx_dropped.

If the XDP program doesn't result in XDP_PASS then we leak the
memory allocated by am65_cpsw_build_skb().
It is pointless to allocate SKB memory before running the XDP
program as we would be wasting CPU cycles for cases other than XDP_PASS.
Move the SKB allocation after evaluating the XDP program result.
This fixes the memleak. A performance boost is seen for XDP_DROP test.
XDP_DROP test:
Before: 460256 rx/s 0 err/s
After: 784130 rx/s 0 err/s

PRMD register is only meaningful on the beginning stage of exception
entry, and it is overwritten with nested irq or exception.
When CPU runs in VM mode, interrupt need be enabled on host. And the
mode for host had better be kernel mode rather than random or user mode.
When VM is running, the running mode with top command comes from CRMD
register, and running mode should be kernel mode since kernel function
is executing with perf command. It needs be consistent with both top and
perf command.

Cache attribute comes from GPA->HPA secondary mmu page table and is
configured when kvm is enabled. It is the same for all VMs, so remove
duplicated cache attribute setting on vCPU context switch.

This is typo issue and misusage about GCFG feature macro. The code
is wrong, only that it does not cause obvious problem since GCFG is
set again on vCPU context switch.

Commit 69e3a6aa6be2 ("LoongArch: Add checksum optimization for 64-bit

Commit 8bd795fedb84 ("arm64: csum: Fix OoB access in IP checksum code

The notifier hook mechanism in proc and cpuinfo is actually unnecessary
for LoongArch because it's not used anywhere.
It was originally added to the MIPS code in commit d6d3c9afaab4 ("MIPS:
MT: proc: Add support for printing VPE and TC ids"), and LoongArch then
inherited it.
But as the kernel code stands now, this notifier hook mechanism doesn't
really make sense for either LoongArch or MIPS.
In addition, the seq_file forward declaration needs to be moved to its
proper place, as only the show_ipi_list() function in smp.c requires it.
