Before trying to do nested_get_page() in nested_vmx_merge_msr_bitmap(),
we have already checked that the MSR bitmap address is valid (4k aligned
and within physical limits). SDM doesn't specify what happens if the
there is no memory mapped at the valid address, but Intel CPUs treat the
situation as if the bitmap was configured to trap all MSRs.
KVM already does that by returning false and a correct handling doesn't
need the guest-trigerrable warning that was reported by syzkaller:
(The warning was originally there to catch some possible bugs in nVMX.)

Interrupt handling routine was calling req->base.complete() under
spinlock. In most cases this wasn't fatal but when combined with some
of the cipher modes (like LRW) this caused recursion - starting the new
encryption (s5p_aes_crypt()) while still holding the spinlock from
previous round (s5p_aes_complete()).
Beside that, the s5p_aes_interrupt() error handling path could execute
two completions in case of error for RX and TX blocks.
Rewrite the interrupt handling routine and the completion by:
1. Splitting the operations on scatterlist copies from
s5p_aes_complete() into separate s5p_sg_done(). This still should be
done under lock.
The s5p_aes_complete() now only calls req->base.complete() and it has
to be called outside of lock.
2. Moving the s5p_aes_complete() out of spinlock critical sections.
In interrupt service routine s5p_aes_interrupts(), it appeared in few
places, including error paths inside other functions called from ISR.
This code was not so obvious to read so simplify it by putting the
s5p_aes_complete() only within ISR level.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

On POWERNV platform, in order to do DMA via IOMMU (i.e. 32bit DMA in
our case), a device needs an iommu_table pointer set via
set_iommu_table_base().
The codeflow is:
- pnv_pci_ioda2_setup_dma_pe()
- pnv_pci_ioda2_setup_default_config()
- pnv_ioda_setup_bus_dma() [1]
pnv_pci_ioda2_setup_dma_pe() creates IOMMU groups,
pnv_pci_ioda2_setup_default_config() does default DMA setup,
pnv_ioda_setup_bus_dma() takes a bus PE (on IODA2, all physical function
PEs as bus PEs except NPU), walks through all underlying buses and
devices, adds all devices to an IOMMU group and sets iommu_table.
On IODA2, when VFIO is used, it takes ownership over a PE which means it
removes all tables and creates new ones (with a possibility of sharing
them among PEs). So when the ownership is returned from VFIO to
the kernel, the iommu_table pointer written to a device at [1] is
stale and needs an update.
This adds an "add_to_group" parameter to pnv_ioda_setup_bus_dma()
(in fact re-adds as it used to be there a while ago for different
reasons) to tell the helper if a device needs to be added to
an IOMMU group with an iommu_table update or just the latter.
This calls pnv_ioda_setup_bus_dma(..., false) from
pnv_ioda2_release_ownership() so when the ownership is restored,
32bit DMA can work again for a device. This does the same thing
on obtaining ownership as the iommu_table point is stale at this point
anyway and it is safer to have NULL there.
We did not hit this earlier as all tested devices in recent years were
only using 64bit DMA; the rare exception for this is MPT3 SAS adapter
which uses both 32bit and 64bit DMA access and it has not been tested
with VFIO much.

Having only 32 memslots is a real constraint for the maximum
number of PCI devices that can be assigned to a single guest.
Assuming each PCI device/virtual function having two memory BAR
regions, we could assign only 15 devices/virtual functions to a

Hence increase KVM_USER_MEM_SLOTS to 512 as done in other archs like

dwc3 got a few fixes this time around:
Fixed an old bug where a broken endpoint descriptor passed in via
userspace through f_fs could prevent dwc3 from working because when
calculating max bursts, we could overwrite top 16 bits of a register.
Also fixed a bug on dwc3's ep_dequeue implementation which wasn't
properly incrementing our TRB dequeue pointer.
dwc3 on omap got two fixes: one for system suspend/resume and another
added a missing break statement on dwc3_omap_set_mailbox().
Apart from these, we have a set of smaller fixes including memory leak
in configfs, build warning fix in atmel udc and a revert of a broken

The IODA2 specification says that a 64 DMA address cannot use top 4 bits
(3 are reserved and one is a "TVE select"); bottom page_shift bits
cannot be used for multilevel table addressing either.
The existing IODA2 table allocation code aligns the minimum TCE table
size to PAGE_SIZE so in the case of 64K system pages and 4K IOMMU pages,
we have 64-4-12=48 bits. Since 64K page stores 8192 TCEs, i.e. needs
13 bits, the maximum number of levels is 48/13 = 3 so we physically
cannot address more and EEH happens on DMA accesses.
This adds a check that too many levels were requested.
It is still possible to have 5 levels in the case of 4K system page size.

This restores the ability to set a team device's mtu to anything higher
than 1500. Similar to the reported issue with bonding, the team driver
calls ether_setup(), which sets an initial max_mtu of 1500, while the
underlying hardware can handle something much larger. Just set it to
ETH_MAX_MTU to support all possible values, and the limitations of the
underlying devices will prevent setting anything too large.
Fixes: 91572088e3fd ("net: use core MTU range checking in core net infra")

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.
