Add functions to handle page faults in the TDP MMU. These page faults
are currently handled in much the same way as the x86 shadow paging
based MMU, however the ordering of some operations is slightly
different. Future patches will add eager NX splitting, a fast page fault
handler, and parallel page faults.
Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell
machine. This series introduced no new failures.

When starting a HP machine with HIL driver but without an HIL keyboard
or HIL mouse attached, it may happen that data written to the HIL loop
gets stuck (e.g. because the transaction queue is full). Usually one
will then have to reboot the machine because all you see is and endless
output of:
Transaction add failed: transaction already queued?
In the higher layers hp_sdc_enqueue_transaction() is called to queued up
a HIL packet. This function returns an error code, and this patch adds
the necessary checks for this return code and disables the HIL driver if
further packets can't be sent.
Tested on a HP 730 and a HP 715/64 machine.

The HP 730 machine returned strange errors when I tried setting the rtc
time. Add some debug code to improve the possibility to trace errors
and document that hppa probably has as Y2k38 problem.

With the set_fs change, we can no longer rely on copy_{to,from}_user()
accepting a kernel pointer, and it was bad form to do so anyway. Clean
this up and change the internal helper that io_uring uses to deal with
kernel pointers instead. This puts the offset copy in/out in __do_splice()
instead, which just calls the same helper.
Signed-off-by: Jens Axboe <axboe@kernel.dk>
We jump through a hoop for fixed buffers, where we first map these to
a bvec(), then kmap() the bvec to obtain the pointer we copy to/from.
This was always a bit ugly, and with the set_fs changes, it ends up
being practically problematic as well.
There's no need to jump through these hoops, just use the original user
pointers and length for the non iter based read/write.

of various clk driver updates. The biggest driver updates in terms of lines of
code is the Allwinner driver, closely followed by the Qualcomm and Mediatek
drivers. All of those hit high because we add so many lines of clk data. Coming
in fourth place is i.MX which also adds a bunch of clk data. This accounts for
the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for various clk
drivers that have baked in linux-next for a while. I suppose one highlight or
theme is that more clk drivers are being updated to work as modules, which is
interesting to see such critical SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module
- Some kerneldoc fixes here and there
- A couple of minor i.MX clk data corrections
- Update audio clock inverter and fdiv2 flag on Amlogic g12
- Make amlogic clk drivers configurable in Kconfig
- Fix Renesas VSP clock names to match corrected hardware documentation
- Sigma-delta modulation on Allwinner R40
- Various fixes for at91 clk driver
- Use semicolons instead of commas in some places
- Mark some variables const so they can move to RO memory

The biggest driver updates in terms of lines of code is the Allwinner
driver, closely followed by the Qualcomm and Mediatek drivers. All of
those hit high because we add so many lines of clk data. Coming in
fourth place is i.MX which also adds a bunch of clk data. This
accounts for the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for
various clk drivers that have baked in linux-next for a while. I
suppose one highlight or theme is that more clk drivers are being
updated to work as modules, which is interesting to see such critical
SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being
dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module
- Some kerneldoc fixes here and there
- A couple of minor i.MX clk data corrections
- Update audio clock inverter and fdiv2 flag on Amlogic g12
- Make amlogic clk drivers configurable in Kconfig
- Fix Renesas VSP clock names to match corrected hardware
documentation
- Sigma-delta modulation on Allwinner R40
- Various fixes for at91 clk driver
- Use semicolons instead of commas in some places
- Mark some variables const so they can move to RO memory"

In the header prediction fast path for a bulk data receiver, if no
data is newly acknowledged then we do not call tcp_ack() and do not
call tcp_ack_update_window(). This means that a bulk receiver that
receives large amounts of data can have the incoming sequence numbers
wrap, so that the check in tcp_may_update_window fails:
after(ack_seq, tp->snd_wl1)
If the incoming receive windows are zero in this state, and then the
connection that was a bulk data receiver later wants to send data,
that connection can find itself persistently rejecting the window
updates in incoming ACKs. This means the connection can persistently
fail to discover that the receive window has opened, which in turn
means that the connection is unable to send anything, and the
connection's sending process can get permanently "stuck".
The fix is to update snd_wl1 in the header prediction fast path for a
bulk data receiver, so that it keeps up and does not see wrapping
problems.
This fix is based on a very nice and thorough analysis and diagnosis
by Apollon Oikonomopoulos (see link below).
This is a stable candidate but there is no Fixes tag here since the
bug predates current git history. Just for fun: looks like the bug
dates back to when header prediction was added in Linux v2.1.8 in Nov
1996. In that version tcp_rcv_established() was added, and the code
only updates snd_wl1 in tcp_ack(), and in the new "Bulk data transfer:
receiver" code path it does not call tcp_ack(). This fix seems to
apply cleanly at least as far back as v3.2.

In setsockopt(SO_MAX_PACING_RATE) on 64bit systems, sk_max_pacing_rate,
after extended from 'u32' to 'unsigned long', takes unintentionally
hiked value whenever assigned from an 'int' value with MSB=1, due to
binary sign extension in promoting s32 to u64, e.g. 0x80000000 becomes
0xFFFFFFFF80000000.
Thus inflated sk_max_pacing_rate causes subsequent getsockopt to return
~0U unexpectedly. It may also result in increased pacing rate.
Fix by explicitly casting the 'int' value to 'unsigned int' before
assigning it to sk_max_pacing_rate, for zero extension to happen.

The IO_REPARSE_TAG_LX_ tags originally were used by WSL but they
are preferred by the Linux client in some cases since, unlike
the NFS reparse tag (or EAs), they don't require an extra query
to determine which type of special file they represent.
Add support for readdir to recognize special file types of
FIFO, SOCKET, CHAR, BLOCK and SYMLINK. This can be tested
by creating these special files in WSL Linux and then
sharing that location on the Windows server and mounting
to the Windows server to access them.
Prior to this patch all of the special files would show up
as being of type 'file' but with this patch they can be seen
with the correct file type as can be seen below:
brwxr-xr-x 1 root root 0, 0 Oct 21 17:10 block
crwxr-xr-x 1 root root 0, 0 Oct 21 17:46 char
drwxr-xr-x 2 root root 0 Oct 21 18:27 dir
prwxr-xr-x 1 root root 0 Oct 21 16:21 fifo
-rwxr-xr-x 1 root root 0 Oct 21 15:48 file
lrwxr-xr-x 1 root root 0 Oct 21 15:52 symlink-to-file
TODO: go through all documented reparse tags to see if we can
reasonably map some of them to directories vs. files vs. symlinks
and also add support for device numbers for block and char
devices.

The "end" pointer is either NULL or it points to the next byte to parse.
If there isn't a next byte then dereferencing "end" is an off-by-one out
of bounds error. And, of course, if it's NULL that leads to an Oops.
Printing "*end" doesn't seem very useful so let's delete this code.
Also for the last debug statement, I noticed that it should be printing
"sequence_end" instead of "end" so fix that as well.

The block layer provides special status codes when requests go beyond
the zone resource limits. Use these codes instead of the generic IOERR
for requests that exceed the max active or open limits the null_blk
device was configured with so that applications know how these special
conditions should be handled.

The avs drivers are all SoC specific drivers that doesn't share any code.
Instead they are located in a directory, mostly to keep similar
functionality together. From a maintenance point of view, it makes better
sense to collect SoC specific drivers like these, into the SoC specific
directories.
Therefore, let's move the qcom-cpr driver to the qcom directory.

Every close(io_uring) causes cancellation of all inflight requests
carrying ->files. That's not nice but was neccessary up until recently.
Now task->files removal is handled in the core code, so that part of
flush can be removed.

We correctly set io-wq NUMA node affinities when the io-wq context is
setup, but if an entire node CPU set is offlined and then brought back
online, the per node affinities are broken. Ensure that we set them
again whenever a CPU comes online. This ensures that we always track
the right node affinity. The usual cpuhp notifiers are used to drive it.

By default, we set the passthru request allocation flag such that it
returns the error in the following code path and we fail the I/O when
BLK_MQ_REQ_NOWAIT is used for request allocation :-
nvme_alloc_request()
blk_mq_alloc_request()
blk_mq_queue_enter()
if (flag & BLK_MQ_REQ_NOWAIT)
return -EBUSY; <-- return if busy.
On some controllers using BLK_MQ_REQ_NOWAIT ends up in I/O error where
the controller is perfectly healthy and not in a degraded state.
Block layer request allocation does allow us to wait instead of
immediately returning the error when we BLK_MQ_REQ_NOWAIT flag is not
used. This has shown to fix the I/O error problem reported under
heavy random write workload.
Remove the BLK_MQ_REQ_NOWAIT parameter for passthru request allocation
which resolves this issue.

Clean up some confusing elements of nvmet_passthru_map_sg() by returning
early if the request is greater than the maximum bio size. This allows
us to drop the sg_cnt variable.
This should not result in any functional change but makes the code
clearer and more understandable. The original code allocated a truncated
bio then would return EINVAL when bio_add_pc_page() filled that bio. The
new code just returns EINVAL early if this would happen.

nvmet_passthru_map_sg() only supports mapping a single BIO, not a chain
so the effective maximum transfer should also be limitted by
BIO_MAX_PAGES (presently this works out to 1MB).
For PCI passthru devices the max_sectors would typically be more
limitting than BIO_MAX_PAGES, but this may not be true for all passthru
devices.

When connecting a controller with a zero kato value using the following
command line
nvme connect -t tcp -n NQN -a ADDR -s PORT --keep-alive-tmo=0
the warning below can be reproduced:
WARNING: CPU: 1 PID: 241 at kernel/workqueue.c:1627 __queue_delayed_work+0x6d/0x90
with trace:
mod_delayed_work_on+0x59/0x90
nvmet_update_cc+0xee/0x100 [nvmet]

nvmet_tcp_try_recv_pdu+0x2f7/0x770 [nvmet_tcp]
nvmet_tcp_io_work+0x63f/0xb2d [nvmet_tcp]
...
This is caused by queuing up an uninitialized work. Althrough the
keep-alive timer is disabled during allocating the controller (fixed in
0d3b6a8d21), ka_work still has a chance to run (called by
nvmet_start_ctrl).

The request's rq_disk isn't set for passthrough IO commands, so tracing
uses qid 0 for these which incorrectly decodes as an admin command. Use
the request_queue's queuedata instead since that value is always set for
the IO queues, and never set for the admin queue.
