2b1a77461f ovl: use vfs_tmpfile_open() helper
If tmpfile is used for copy up, then use this helper to create the tmpfile
and open it at the same time.  This will later allow filesystems such as
fuse to do this operation atomically.

24a81759b6 cachefiles: use vfs_tmpfile_open() helper
Use the vfs_tmpfile_open() helper instead of doing tmpfile creation and
opening separately.

The only minor difference is that previously no permission checking was
done, while vfs_tmpfile_open() will call may_open() with zero access mask
(i.e. no access is checked).  Even if this would make a difference with
callers caps (don't see how it could, even in the LSM codepaths) cachfiles
raises caps before performing the tmpfile creation, so this extra
permission check will not result in any regression.

08d7a6fb7e cachefiles: only pass inode to *mark_inode_inuse() helpers
The only reason to pass dentry was because of a pr_notice() text.  Move
that to the two callers where it makes sense and add a WARN_ON() to the
third.

file_inode(file) is never NULL on an opened file. Remove check in
cachefiles_unmark_inode_in_use().

Do not open code cachefiles_do_unmark_inode_in_use() in
cachefiles_put_directory().

19ee5345f2 hugetlbfs: cleanup mknod and tmpfile
Duplicate the few lines that are shared between hugetlbfs_mknod() and
hugetlbfs_tmpfile().

This is a prerequisite for sanely changing the signature of ->tmpfile().

22873deac9 vfs: add vfs_tmpfile_open() helper
This helper unifies tmpfile creation with opening.

Existing vfs_tmpfile() callers outside of fs/namei.c will be converted to
using this helper.  There are two such callers: cachefile and overlayfs.

The cachefiles code currently uses the open_with_fake_path() helper to open
the tmpfile, presumably to disable accounting of the open file.  Overlayfs
uses tmpfile for copy_up, which means these struct file instances will be
short lived, hence it doesn't really matter if they are accounted or not.
Disable accounting in this helper too, which should be okay for both
callers.

Add MAY_OPEN permission checking for consistency.  Like for create(2)
read/write permissions are not checked.

Merge tag 'parisc-for-6.0-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc architecture fixes from Helge Deller:
 "Some small parisc architecture fixes for 6.0-rc6:

  One patch lightens up a previous commit and thus unbreaks building the
  debian kernel, which tries to configure a 64-bit kernel with the
  ARCH=parisc environment variable set.

  The other patches fixes asm/errno.h includes in the tools directory
  and cleans up memory allocation in the iosapic driver.

  Summary:

   - Allow configuring 64-bit kernel with ARCH=parisc

   - Fix asm/errno.h includes in tools directory for parisc and xtensa

   - Clean up iosapic memory allocation

   - Minor typo and spelling fixes"

sets the variable "len" to the length in sectors, but the statement
"bio->bi_iter.bi_size = len" treats it as if it were in bytes.

805ce86149 parisc: Allow CONFIG_64BIT with ARCH=parisc
The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.

This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
    ARCH=parisc     -> build 32-bit kernel
    ARCH=parisc64   -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).

The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

a8671493d2 drm/amdgpu: make sure to init common IP before gmc
Move common IP init before GMC init so that HDP gets
remapped before GMC init which uses it.

This fixes the Unsupported Request error reported through
AER during driver load. The error happens as a write happens
to the remap offset before real remapping is done.

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather

e3163bc8ff drm/amdgpu: move nbio sdma_doorbell_range() into sdma code for vega
This mirrors what we do for other asics and this way we are
sure the sdma doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  However, the statement says that it applies to
multimedia as well, but the VCN code currently initializes
doorbells after GFX and there are no known issues there.  In my
testing at least I don't see any problems on SDMA.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

c297561bc9 pinctrl: ocelot: Fix interrupt controller
When an external device generated a level based interrupt then the
interrupt controller could miss the interrupt. The reason is that the
interrupt controller can detect only link changes.

In the following example, if there is a PHY that generates an interrupt
then the following would happen. The GPIO detected that the interrupt
line changed, and then the 'ocelot_irq_handler' was called. Here it
detects which GPIO line saw the change and for that will call the
following:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

And this works fine for simple cases, but if the PHY generates many
interrupts, for example when doing PTP timestamping, then the following
could happen. Again the function 'ocelot_irq_handler' will be called
and then from here the following could happen:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

Right before step 3(irq_eoi), the PHY will generate another interrupt.
Now the interrupt controller will acknowledge the change in the
interrupt line. So we miss the interrupt.

A solution will be to use 'handle_level_irq' instead of
'handle_fasteoi_irq', because for this will change routine order of
handling the interrupt.
1. irq_mask
2. irq_ack
3. phy interrupt routine
4. irq_unmask

And now if the PHY will generate a new interrupt before irq_unmask, the
interrupt controller will detect this because it already acknowledge the
change in interrupt line at step 2(irq_ack).

But this is not the full solution because there is another issue. In
case there are 2 PHYs that share the interrupt line. For example phy1
generates an interrupt, then the following can happen:
1.irq_mask
2.irq_ack
3.phy0 interrupt routine
4.phy1 interrupt routine
5.irq_unmask

In case phy0 will generate an interrupt while clearing the interrupt
source in phy1, then the interrupt line will be kept down by phy0. So
the interrupt controller will not see any changes in the interrupt line.
The solution here is to update 'irq_unmask' such that it can detect if
the interrupt line is still active or not. And if it is active then call
again the procedure to clear the interrupts. But we don't want to do it
every time, only if we know that the interrupt controller has not seen
already that the interrupt line has changed.

While at this, add support also for IRQ_TYPE_LEVEL_LOW.

The mode_valid field in drm_connector_helper_funcs is expected to be of

enum drm_mode_status (* mode_valid) (struct drm_connector *connector,

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of cdn_dp_connector_mode_valid should be changed from
int to enum drm_mode_status.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
  void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
       ^
  1 error generated.

Commit a0f7e7f759 ("drm/amd/display: fix i386 frame size warning")
aimed to address this for i386 but it did not help x86_64.

To reduce the amount of stack space that
dml30_ModeSupportAndSystemConfigurationFull() uses, mark
UseMinimumDCFCLK() as noinline, using the _for_stack variant for
documentation. While this will increase the total amount of stack usage
between the two functions (1632 and 1304 bytes respectively), it will
make sure both stay below the limit of 2048 bytes for these files. The
aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage
so it should not be reverted in favor of this change.

3601d620f2 drm/amd/display: Limit user regamma to a valid value
[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.

[How]
Limit the value when coordinates_x.x > 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.

ceb756004a drm/amd/display: add workaround for subvp cursor corruption for DCN32/321
[Why&How]
Kernel does not have a means to tell the userspace to use software
cursor. Due to lack of this functionality, reducing the max cursor size
is the only way to ensure that power savings of Subview port feature is
utilized for asics that support it. The workaround could be removed
after cursor caching is fixed while a subviewport config is active.

[Description]
Leverage SW cursor fall back for SubVP when the cursor is too big. We
want to take advantage of being able to fallback to SW cursor when
possible because it's not worth it to disable MCLK switching because the
cursor is slightly too big.
