The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

It turns out that the vfs_iocb_iter_{read,write}() functions are
entirely broken, and don't actually use the passed-in file pointer for
IO - only for the preparatory work (permission checking and for the
write_iter function lookup).

That worked fine for overlayfs, which always builds the new iocb with
the same file pointer that it passes in, but in the general case it ends
up doing nonsensical things (and could cause an iterator call that
doesn't even match the passed-in file pointer).

This subtly broke the tty conversion to write_iter in commit
9bb48c82 ("tty: implement write_iter"), because the console
redirection didn't actually end up redirecting anything, since the
passed-in file pointer was basically ignored, and the actual write was
done with the original non-redirected console tty after all.

The main visible effect of this is that the console messages were no
longer logged to /var/log/boot.log during graphical boot.

Fix the issue by simply not using the vfs write "helper" function at
all, and just redirecting the write entirely internally to the tty
layer.  Do the target writability permission checks when actually
registering the target tty with TIOCCONS instead of at write time.

While we do handle the additional cursor sizes introduced in NVE4, it looks
like we accidentally broke this when converting over to use Nvidia's
display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
format the value for the cursor layout and NVD9 only had one byte reserved
vs. the 2 bytes reserved in later generations, we end up accidentally
stripping the second bit in the cursor layout format parameter - causing us
to set the wrong cursor size.

This fixes that by adding our own curs_set hook for 917d which uses the
NV917D headers.

Commit f844eb48 introduced a regression for
NV50, which lead to visual artifacts, tearing and eventual crashes.

In the changes of f844eb48 only the first line
was correctly translated to the new NVIDIA header macros:

-		PUSH_NVSQ(push, NV827C, 0x0110, 0,
-					0x0114, 0);
+		PUSH_MTHD(push, NV827C, SET_PROCESSING,
+			  NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE));

The lower part ("0x0114, 0") was probably omitted by accident.

This patch restores the push of the missing data and fixes the regression.

What 84965ff8 ("io_uring: if we see flush on exit, cancel related tasks")
really wants is to cancel all relevant REQ_F_INFLIGHT requests reliably.
That can be achieved by io_uring_cancel_files(), but we'll miss it
calling io_uring_cancel_task_requests(files=NULL) from io_uring_flush(),
because it will go through __io_uring_cancel_task_requests().

Just always call io_uring_cancel_files() during cancel, it's good enough
for now.

Ido Schimmel says:

====================
mlxsw: Various fixes

Patch #1 fixes wrong invocation of mausezahn in a couple of selftests.
The tests started failing after Fedora updated their libnet package from
version 1.1.6 to 1.2.1. With the fix the tests pass regardless of libnet
version.

Patch #2 fixes an issue in the mirroring to CPU code that results in
policer configuration being overwritten.

The purpose of the delayed work in the SPAN module is to potentially
update the destination port and various encapsulation parameters of SPAN
agents that point to a VLAN device or a GRE tap. The destination port
can change following the insertion of a new route, for example.

SPAN agents that point to a physical port or the CPU port are static and
never change throughout the lifetime of the SPAN agent. Therefore, skip
over them in the delayed work.

This fixes an issue where the delayed work overwrites the policer
that was set on a SPAN agent pointing to the CPU. Modifying the delayed
work to inherit the original policer configuration is error-prone, as
the same will be needed for any new parameter.

Specify the interface through which packets should be transmitted so
that the test will pass regardless of the libnet version against which
mausezahn is linked.

Fix an issue where dump stack is printed and Reset Adapter occurs when
PSE0 GbE or/and PSE1 GbE is/are enabled. EHL PSE0 GbE and PSE1 GbE use
32 bits DMA addressing whereas EHL PCH GbE uses 64 bits DMA addressing.

Pull locking fixes from Thomas Gleixner:
 "A set of PI futex fixes:

   - Address a longstanding issue where the user space part of the PI
     futex is not writeable. The kernel returns with inconsistent state
     which can in the worst case result in a UAF of a tasks kernel
     stack.

     The solution is to establish consistent kernel state which makes
     future operations on the futex fail because user space and kernel
     space state are inconsistent. Not a problem as PI futexes
     fundamentaly require a functional RW mapping and if user space
     pulls the rug under it, then it can keep the pieces it asked for.

   - Address an issue where the return value is incorrect in case that
     the futex was acquired after a timeout/signal made the waiter drop
     out of the rtmutex wait.

     In one of the corner cases the kernel returned an error code
     despite having successfully acquired the futex"

  futex: Handle faults correctly for PI futexes
  futex: Simplify fixup_pi_state_owner()

  futex: Provide and use pi_state_update_owner()
  futex: Replace pointless printk in fixup_owner()

Now io_uring_cancel_task_requests() can be called not through file
notes but directly, remove a WARN_ONCE() there that give us false
positives. That check is not very important and we catch it in other
places.
