The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on probe
due to a malfunctioning (or malicious) device until the device is
physically disconnected. While sleeping in probe the driver prevents
other devices connected to the same hub from being added to (or removed
from) the bus.
The USB upper limit of five seconds per request should be more than
enough.

The F54 Report Data is apparently read through a fifo and for
the smbus protocol that means that between reading a block of 32
bytes the rmiaddr shouldn't be incremented. However, changing
that causes other non-fifo reads to fail and so that change was
reverted.
This patch changes just the F54 function and it now reads 32 bytes
at a time from the fifo, using the F54_FIFO_OFFSET to update the
start address that is used when reading from the fifo.
This has only been tested with smbus, not with i2c or spi. But I
suspect that the same is needed there since I think similar
problems will occur there when reading more than 256 bytes.

Implement the H_SVM_INIT_ABORT hcall which the Ultravisor can use to
abort an SVM after it has issued the H_SVM_INIT_START and before the
H_SVM_INIT_DONE hcalls. This hcall could be used when Ultravisor
encounters security violations or other errors when starting an SVM.
Note that this hcall is different from UV_SVM_TERMINATE ucall which
is used by HV to terminate/cleanup an VM that has becore secure.
The H_SVM_INIT_ABORT basically undoes operations that were done
since the H_SVM_INIT_START hcall - i.e page-out all the VM pages back
to normal memory, and terminate the SVM.
(If we do not bring the pages back to normal memory, the text/data
of the VM would be stuck in secure memory and since the SVM did not
go secure, its MSR_S bit will be clear and the VM wont be able to
access its pages even to do a clean exit).

Toke Høiland-Jørgensen says:
====================
Since commit 96360004b8 ("xdp: Make devmap flush_list common for all map
instances"), devmap flushing is a global operation instead of tied to a
particular map. This means that with a bit of refactoring, we can finally fix
the performance delta between the bpf_redirect_map() and bpf_redirect() helper
functions, by introducing bulking for the latter as well.
This series makes this change by moving the data structure used for the bulking
into struct net_device itself, so we can access it even when there is not
devmap. Once this is done, moving the bpf_redirect() helper to use the bulking
mechanism becomes quite trivial, and brings bpf_redirect() up to the same as
bpf_redirect_map():
Before: After:
1 CPU:
bpf_redirect_map: 8.4 Mpps 8.4 Mpps (no change)
bpf_redirect: 5.0 Mpps 8.4 Mpps (+68%)
2 CPUs:
bpf_redirect_map: 15.9 Mpps 16.1 Mpps (+1% or ~no change)
bpf_redirect: 9.5 Mpps 15.9 Mpps (+67%)
After this patch series, the only semantics different between the two variants
of the bpf() helper (apart from the absence of a map argument, obviously) is
that the _map() variant will return an error if passed an invalid map index,
whereas the bpf_redirect() helper will succeed, but drop packets on
xdp_do_redirect(). This is because the helper has no reference to the calling
netdev, so unfortunately we can't do the ifindex lookup directly in the helper.
Changelog:
v3:
- Switch two more fields to avoid a list_head spanning two cache lines
- Include Jesper's tracepoint patch
- Also rename xdp_do_flush_map()
- Fix a few nits from Maciej
v2:
- Consolidate code paths and tracepoints for map and non-map redirect variants
(Björn)
- Add performance data for 2-CPU test (Jesper)
- Move fields to avoid shifting cache lines in struct net_device (Eric)

Now that we don't have a reference to a devmap when flushing the device
bulk queue, let's change the the devmap_xmit tracepoint to remote the
map_id and map_index fields entirely. Rearrange the fields so 'drops' and
'sent' stay in the same position in the tracepoint struct, to make it
possible for the xdp_monitor utility to read both the old and the new
format.

Since the bulk queue used by XDP_REDIRECT now lives in struct net_device,
we can re-use the bulking for the non-map version of the bpf_redirect()
helper. This is a simple matter of having xdp_do_redirect_slow() queue the
frame on the bulk queue instead of sending it out with __bpf_tx_xdp().
Unfortunately we can't make the bpf_redirect() helper return an error if
the ifindex doesn't exit (as bpf_redirect_map() does), because we don't
have a reference to the network namespace of the ingress device at the time
the helper is called. So we have to leave it as-is and keep the device
lookup in xdp_do_redirect_slow().
Since this leaves less reason to have the non-map redirect code in a
separate function, so we get rid of the xdp_do_redirect_slow() function
entirely. This does lose us the tracepoint disambiguation, but fortunately
the xdp_redirect and xdp_redirect_map tracepoints use the same tracepoint
entry structures. This means both can contain a map index, so we can just
amend the tracepoint definitions so we always emit the xdp_redirect(_err)
tracepoints, but with the map ID only populated if a map is present. This
means we retire the xdp_redirect_map(_err) tracepoints entirely, but keep
the definitions around in case someone is still listening for them.
With this change, the performance of the xdp_redirect sample program goes
from 5Mpps to 8.4Mpps (a 68% increase).
Since the flush functions are no longer map-specific, rename the flush()
functions to drop _map from their names. One of the renamed functions is
the xdp_do_flush_map() callback used in all the xdp-enabled drivers. To
keep from having to update all drivers, use a #define to keep the old name
working, and only update the virtual drivers in this patch.

Commit 96360004b8 ("xdp: Make devmap flush_list common for all map
instances"), changed devmap flushing to be a global operation instead of a
per-map operation. However, the queue structure used for bulking was still
allocated as part of the containing map.
This patch moves the devmap bulk queue into struct net_device. The
motivation for this is reusing it for the non-map variant of XDP_REDIRECT,
which will be changed in a subsequent commit. To avoid other fields of
struct net_device moving to different cache lines, we also move a couple of
other members around.
We defer the actual allocation of the bulk queue structure until the
NETDEV_REGISTER notification devmap.c. This makes it possible to check for
ndo_xdp_xmit support before allocating the structure, which is not possible
at the time struct net_device is allocated. However, we keep the freeing in
free_netdev() to avoid adding another RCU callback on NETDEV_UNREGISTER.
Because of this change, we lose the reference back to the map that
originated the redirect, so change the tracepoint to always return 0 as the
map ID and index. Otherwise no functional change is intended with this
patch.
After this patch, the relevant part of struct net_device looks like this,
according to pahole:

There is ongoing work to make all (not just bpf_helper_defs.h) includes more
consistent across libbpf and its consumers, but this unbreaks user code as is
right now without any regressions. Selftests still behave sub-optimally

- Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit
- Build fixlets (selects) for davinci/omap2+
- More interrupt number fixes for Stratix10, Amlogic SM1, etc.
- ... and more similar fixes across different platforms

cpuidle: teo: Fix intervals[] array indexing bug
Increase the number of chains and priorities to support
the whole range available in tc.
We use unmanaged tables and ignore flow level to create more
tables than what we declared to fs_core steering, and we manage
the connections between the tables themselves.
To support that we need FW with ignore_flow_level capability.
Otherwise the old behaviour will be used, where we are limited
by the number of levels we declared (4 chains, 16 prios).

To support the entire chain and prio range (32bit + 16bit),
instead of a using a static array of chains/prios of limited size, create
them dynamically, and use a rhashtable to search for existing chains/prio
combinations.
This will be used in next patch to actually increase the number using
unamanged tables support and ignore flow level capability.

Before changing the chain from original chain to ft offload chain,
make sure user doesn't actually use chains.
While here, normalize the prio range to that which we support.

FT chain is defined as the next chain after tc.
To prepare for next patches that will increase the number of tc
chains available at runtime, use a getter function to get this
value.
The define is still used in static fs_core allocation,
to calculate the number of chains. This static allocation
will be used if the relevant capabilities won't be available
to support dynamic chains.

Exclude the last n entries for an autogrouped flow table.
Reserving entries at the end of the FT will ensure that this FG will be
the last to be evaluated. This will be used in the next patch to create
a miss group enabling custom actions on FT miss.

If user sets ignore flow level flag on a rule, that rule can point to
a flow table of any level, including those with levels equal or less
than the level of the flow table it is added on.
This with unamanged tables will be used to create a FDB chain/prio
hierarchy much larger than currently supported level range.

Currently, Most of the steering tree is statically declared ahead of time,
with steering prios instances allocated for each fdb chain to assign max
number of levels for each of them. This allows fs_core to manage the
connections and levels of the flow tables hierarcy to prevent loops, but
restricts us with the number of supported chains and priorities.
Introduce unmananged flow tables, allowing the user to manage the flow
table connections. A unamanged table is detached from the fs_core flow
table hierarcy, and is only connected back to the hierarchy by explicit
FTEs forward actions.
This will be used together with firmware that supports ignoring the flow
table levels to increase the number of supported chains and prios.

__kernel_ino_t is "unsigned long" on most architectures, but not on
alpha and s390x, where it is "unsigned int". Hence when printing an
ino_t, it should always be cast to "unsigned long" first.
Fix this by re-adding the recently removed casts.
