The Terra Pad 1061 has the usual micro-USB-B id-pin handler, but instead
of controlling the actual micro-USB-B it turns the 5V boost for the
tablet's USB-A connector and its keyboard-cover connector off.
The actual micro-USB-B connector on the tablet is wired for charging only,
and its id pin is *not* connected to the GPIO which is used for the
(broken) id-pin event handler in the DSDT.
While at it not only add a comment why the Terra Pad 1061 is on the
blacklist, but also fix the missing comment for the Minix Neo Z83-4 entry.

Netfilter tables (nftables) implements a software datapath that
comes after tc ingress datapath. The datapath supports offloading
such rules via the flow table offload API.
This API is currently only used by NFT and it doesn't provide the
global priority in regards to tc offload, so we assume offloading such
rules must come after tc. It does provide a flow table priority
parameter, so we need to provide some supported priority range.
For that, split fastpath prio to two, flow table offload and tc offload,
with one dedicated priority chain for flow table offload.
Next patch will re-use the multi chain API to access this chain by
allowing access to this chain by the fdb_sub_namespace.

Tc chains are implemented by creating a chained prio steering type, and
inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each
of those has a list of priorities.
Currently, all namespaces in a prio start at the parent prio level.
But since we can jump from chain (namespace) to another chain in the
same prio, we need the levels for higher chains to be higher as well.
So we created unused prios to account for levels in previous namespaces.
Fix that by accumulating the namespaces levels if we are inside a chained
type prio, and removing the unused prios.

If the current state with the maximum "early hits" metric in
teo_select() is also the one "matching" the expected idle duration,
it will be used as the candidate one for selection even if its
"misses" metric is greater than its "hits" metric, which is not
correct.
In that case, the candidate state should be shallower than the
current one and its "early hits" metric should be the maximum
among the idle states shallower than the current one.
To make that happen, modify teo_select() to save the index of
the state whose "early hits" metric is the maximum for the
range of states below the current one and go back to that state
if it turns out that the current one should be rejected.

The RISC-V ISA only supports flushing the instruction cache for the
local CPU core. Currently we always offload the remote TLB flushing to
the SBI, which then issues an IPI under the hoods. But with M-mode
we do not have an SBI so we have to do it ourselves. IPI to the
other nodes using the existing kernel helpers instead if we have
native clint support and thus can IPI directly from the kernel.

This reverts commit f4071997f1.
These extra EHL entries won't behave as expected without a bit more work
on the kernel side so let's drop them until that kernel work has had a
chance to land. Userspace trying to use these new entries won't get the
advantage of the new functionality these entries are meant to provide,
but at least it won't misbehave.
When we do add these back in the future, we'll probably want to
explicitly use separate tables for ICL and EHL so that userspace
software that mistakenly uses these entries (which are undefined on ICL)
sees the same behavior it sees with all the other undefined entries.

worker->cur_work is currently protected by the lock of the wqe that the
worker belongs to. When we send a signal to a worker, we need a stable
view of ->cur_work, so we need to hold that lock. But this doesn't work
so well, since we have the opposite order potentially on queueing work.
If POLL_ADD is used with a signalfd, then io_poll_wake() is called with
the signal lock, and that sometimes needs to insert work items.
Add a specific worker lock that protects the current work item. Then we
can guarantee that the task we're sending a signal is currently
processing the exact work we think it is.

Set the STATX_ATTR_VERITY bit when the statx() system call is used on a

Signed-off-by: Eric Biggers <ebiggers@google.com>
Add a statx attribute bit STATX_ATTR_VERITY which will be set if the
file has fs-verity enabled. This is the statx() equivalent of
FS_VERITY_FL which is returned by FS_IOC_GETFLAGS.
This is useful because it allows applications to check whether a file is
a verity file without opening it. Opening a verity file can be
expensive because the fsverity_info is set up on open, which involves
parsing metadata and optionally verifying a cryptographic signature.
This is analogous to how various other bits are exposed through both
FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit.

The ohci driver uses the get_seconds() function to implement the 32-bit
CSR_BUS_TIME register. This was added in 2010 commit a48777e03a
("firewire: add CSR BUS_TIME support").
As get_seconds() returns a 32-bit value (on 32-bit architectures), it
seems like a good fit for that register, but it is also deprecated because
of the y2038/y2106 overflow problem, and should be replaced throughout
the kernel with either ktime_get_real_seconds() or ktime_get_seconds().
I'm using the latter here, which uses monotonic time. This has the
advantage of behaving better during concurrent settimeofday() updates
or leap second adjustments and won't overflow a 32-bit integer, but
the downside of using CLOCK_MONOTONIC instead of CLOCK_REALTIME is
that the observed values are not related to external clocks.
If we instead need UTC but can live with clock jumps or overflows,
then we should use ktime_get_real_seconds() instead, retaining the
existing behavior.

- Moved the Tx and Rx buffer initialization rework to its own patch.
Since v1:
- Stopped using state->link in mac_config and moved macb_set_tx_clk to
the link_up helper..
- Fixed the node given to phylink_of_phy_connect.
- Removed netif_carrier_off from macb_open.
- Fixed the macb_get_wol logic.
- Rewored macb_ioctl as suggested.
- Added a call to phylink_destroy in macb_remove.
- Fixed the suspend/resume case by calling phylink_start/stop in the
resume/suspend helpers. I had to take the rtnl lock to do this,
which might be something to discuss.

This patch converts the MACB Ethernet driver to the Phylink framework.
The MAC configuration is moved to the Phylink ops and Phylink helpers
are now used in the ethtools functions. This helps to access the flow
control and pauseparam logic and this will be helpful in the future for
boards using this controller with SFP cages.

This patch moves the Tx and Rx buffer initialization into its own
function. This does not modify the behaviour of the driver and will be
helpful to convert the driver to phylink.

To enable xilinx axi_emac driver support on zynqmp ultrascale platform
(ARCH64) there are two choices, mention ARCH64 as a dependency list
and other is to check if this ARCH dependency list is really needed.
Later approach seems more reasonable, so remove the obsolete ARCH
dependency list for the axi_emac driver.
Sanity test done for microblaze, zynq and zynqmp ultrascale platform.

Add support for flow steering counters action with a non-base counter
ID (offset) for bulk counters.
When creating a flow counter object, save the bulk value. This value is
used when a flow action with a non-base counter ID is requested - to
validate that the required offset is in the range of the allocated bulk.
