arm64: mm: Don't invalidate FROM_DEVICE buffers at start of DMA transfer
Invalidating the buffer memory in arch_sync_dma_for_device() for
FROM_DEVICE transfers
When using the streaming DMA API to map a buffer prior to inbound
non-coherent DMA (i.e. DMA_FROM_DEVICE), we invalidate any dirty CPU
cachelines so that they will not be written back during the transfer and
corrupt the buffer contents written by the DMA. This, however, poses two
potential problems:
(1) If the DMA transfer does not write to every byte in the buffer,
then the unwritten bytes will contain stale data once the transfer
has completed.
(2) If the buffer has a virtual alias in userspace, then stale data
may be visible via this alias during the period between performing
the cache invalidation and the DMA writes landing in memory.
Address both of these issues by cleaning (aka writing-back) the dirty
lines in arch_sync_dma_for_device(DMA_FROM_DEVICE) instead of discarding
them using invalidation.

arm64/cpufeature: Unexport set_cpu_feature()
We currently export set_cpu_feature() to modules but there are no in tree users that can be built as modules and it is hard to see cases where it would make sense for there to be any such users. Remove the export to avoid anyone else having to worry about why it is there and ensure that any users that do get added get a bit more visiblity.

arm64: ftrace: consistently handle PLTs.
Sometimes it is necessary to use a PLT entry to call an ftrace trampoline. This is handled by ftrace_make_call() and ftrace_make_nop(), with each having *almost* identical logic, but this is not handled by ftrace_modify_call() since its introduction in commit: |

arm64: ftrace: fix branch range checks
The branch range checks in ftrace_make_call() and ftrace_make_nop() are incorrect, erroneously permitting a forwards branch of 128M and erroneously rejecting a backwards branch of 128M. This is because both functions calculate the offset backwards, calculating the offset *from* the target *to* the branch, rather than the other way around as the later comparisons expect. If an out-of-range branch were erroeously permitted, this would later be rejected by aarch64_insn_gen_branch_imm() as branch_imm_common() checks the bounds correctly, resulting in warnings and the placement of a BRK instruction. Note that this can only happen for a forwards branch of exactly 128M, and so the caller would need to be exactly 128M bytes below the relevant ftrace trampoline. If an in-range branch were erroeously rejected, then: * For modules when CONFIG_ARM64_MODULE_PLTS=y, this would result in the use of a PLT entry, which is benign. Note that this is the common case, as this is selected by CONFIG_RANDOMIZE_BASE (and therefore RANDOMIZE_MODULE_REGION_FULL), which distributions typically seelct. This is also selected by CONFIG_ARM64_ERRATUM_843419. * For modules when CONFIG_ARM64_MODULE_PLTS=n, this would result in internal ftrace failures. * For core kernel text, this would result in internal ftrace failues. Note that for this to happen, the kernel text would need to be at least 128M bytes in size, and typical configurations are smaller tha this. Fix this by calculating the offset *from* the branch *to* the target in both functions. Fixes: |

arm64/sme: Fix EFI save/restore
The EFI save/restore code is confused. When saving the check for saving
FFR is inverted due to confusion with the streaming mode check, and when
restoring we check if we need to restore FFR by checking the percpu
efi_sm_state without the required wrapper rather than based on the
combination of FA64 support and streaming mode.

KVM: arm64: Extend comment in has_vhe()
has_vhe() expands to a compile-time constant when evaluated from the VHE or nVHE code, alternatively checking a static key when called from elsewhere in the kernel. On face value, this looks like a case of premature optimization, but in fact this allows symbol references on VHE-specific code paths to be dropped from the nVHE object. Expand the comment in has_vhe() to make this clearer, hopefully discouraging anybody from simplifying the code.

KVM: arm64: Handle all ID registers trapped for a protected VM
A protected VM accessing ID_AA64ISAR2_EL1 gets punished with an UNDEF, while it really should only get a zero back if the register is not handled by the hypervisor emulation (as mandated by the architecture).

arm64/sme: Fix tests for 0b1111 value ID registers
For both ID_AA64SMFR0_EL1.I16I64 and ID_AA64SMFR0_EL1.I8I32 we check for
the presence of the feature by looking for a specific ID value of 0x4 but
should instead be checking for the value 0xf defined by the architecture.
This had no practical effect since we are looking for values >= our define
and the only valid values in the architecture are 0b0000 and 0b1111 so we
would detect things appropriately with the architecture as it stands even
with the incorrect defines.

KVM: arm64: Warn if accessing timer pending state outside of vcpu context
A recurrent bug in the KVM/arm64 code base consists in trying to access the timer pending state outside of the vcpu context, which makes zero sense (the pending state only exists when the vcpu is loaded). In order to avoid more embarassing crashes and catch the offenders red-handed, add a warning to kvm_arch_timer_get_input_level() and return the state as non-pending. This avoids taking the system down, and still helps tracking down silly bugs.

KVM: arm64: Replace vgic_v3_uaccess_read_pending with vgic_uaccess_read_pending
Now that GICv2 has a proper userspace accessor for the pending state, switch GICv3 over to it, dropping the local version, moving over the specific behaviours that CGIv3 requires (such as the distinction between pending latch and line level which were never enforced with GICv2). We also gain extra locking that isn't really necessary for userspace, but that's a small price to pay for getting rid of superfluous code.

KVM: arm64: Always start with clearing SME flag on load
On each vcpu load, we set the KVM_ARM64_HOST_SME_ENABLED
flag if SME is enabled for EL0 on the host. This is used to
restore the correct state on vpcu put.
However, it appears that nothing ever clears this flag. Once
set, it will stick until the vcpu is destroyed, which has the
potential to spuriously enable SME for userspace. As it turns
out, this is due to the SME code being more or less copied from
SVE, and inheriting the same shortcomings.
We never saw the issue because nothing uses SME, and the amount
of testing is probably still pretty low.

USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the
USB core, but there are the usual "hot spots" of development activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported
problems.

arm64: Initialize jump labels before setup_machine_fdt()
A static key warning splat appears during early boot on arm64 systems
that credit randomness from devicetrees that contain an "rng-seed"
property. This is because setup_machine_fdt() is called before
jump_label_init() during setup_arch(). Let's swap the order of these two
calls so that jump labels are initialized before the devicetree is
unflattened and the rng seed is credited.
