A resource will be a shmem based resource or a (planned)
vram based resource, so it makes sense to factor out common fields
(resource handle, dumb).

Pull the drm_pci_agp_init() underneath the legacy ifdeffry alongside its
only caller.
The diff chooses it to so it by moving drm_pci_agp_destroy earlier, but
the important bit is moving the #ifdef earlier before drm_pci_agp_init.

We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was
a miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing for
a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms.

Be sure to wait for the vma to be in place before we tell the GPU to
execute from the wa batch. Since initialisation is mostly synchronous
(or rather at some point during start up we will need to sync anyway),
we can affort to do an explicit i915_vma_sync() during wa batch
construction rather than check for a required await on every context
switch. (We don't expect to change the wa bb at run time so paying the
cost once up front seems preferrable.)

There is a recipe to deadlock the kernel: submit a timeout sqe with a
linked_timeout (e.g. test_single_link_timeout_ception() from liburing),
and SIGKILL the process.
Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout
isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it
during io_put_free() to cancel the linked timeout. Probably, the same
can happen with another io_kill_timeout() call site, that is
io_commit_cqring().

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

This fixes the case where we are inspecting the last->next element when

This Kselftest update for Linux 5.6-rc5 consists of a cleanup patch
to undo changes to global .gitignore that added selftests/lkdtm
objects and add them to a local selftests/lkdtm/.gitignore.
Summary of Linus's comments on local vs. global gitignore scope:
- Keep local gitignore patterns in local files.
- Put only global gitignore patterns in the top-level gitignore file.
Local scope keeps things much better separated. It also incidentally
means that if a directory gets renamed, the gitignore file continues
to work unless in the case of renaming the actual files themselves that
are named in the gitignore.

Pull RISC-V fixes from Palmer Dabbelt:
"This contains a handful of fixes that I would like to target for 5.6:
- A pair of fixes to module loading, which we hope solve the last of
the issues with module text being loaded too sparsely for our call
relocations.
- A Kconfig fix that disallows selecting memory models not supported
by NOMMU.
- A series of Kconfig updates to ease selecting the drivers necessary
to run on QEMU's virt platform.
- DTS updates for SiFive's HiFive Unleashed.
- A fix to our seccomp support that avoids mangling restartable
syscalls"
* tag 'riscv-for-linus-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
riscv: fix seccomp reject syscall code path
riscv: dts: Add GPIO reboot method to HiFive Unleashed DTS file
RISC-V: Select Goldfish RTC driver for QEMU virt machine
RISC-V: Select SYSCON Reboot and Poweroff for QEMU virt machine

riscv: Fix range looking for kernel image memblock
riscv: Force flat memory model with no-mmu
riscv: Change code model of module to medany to improve data accessing
riscv: avoid the PIC offset of static percpu data in module beyond 2G limits
On some platforms such as Elkhart Lake, although we may use DDI D
to drive a connector, we have to use PHY A (Combo Phy PORT A) to
detect the hotplug interrupts as per the spec because there is no
one-to-one mapping between DDIs and PHYs. Therefore, use the
function intel_port_to_phy() which contains the logic for such
mapping(s) to find the correct hpd_pin.
This change should not affect other platforms as there is always
a one-to-one mapping between DDIs and PHYs.
v2:
- Convert the case statements to use PHYs instead of PORTs (Jani)
v3:
- Refactor the function to reduce the number of return statements by
lumping all the case statements together except PHY_F which needs
special handling (Jose)
v4:
- Add a comment describing how the HPD pin value associated with any
port can be retrieved using port or phy enum value. (Jani)
v5:
- Use case ranges instead of individual labels and also normalize the
return statement by adding -PHY_A to the expression (Ville)

When resize the screen, update the 'vc->vc_size_row' to the new_row_size,
but when 'set_origin' in 'vgacon_set_origin', vgacon use 'vga_vram_base'
for 'vc_origin' and 'vc_visible_origin', not 'vc_screenbuf'. It maybe
smaller than 'vc_screenbuf'. When TIOCLINUX, use the new_row_size to calc
the offset, it maybe larger than the vga_vram_size in vgacon driver, then
bad access.
Also, if set an larger screenbuf firstly, then set an more larger
screenbuf, when copy old_origin to new_origin, a bad access may happen.
So, If the screen size larger than vga_vram, resize screen should be
failed. This alse fix CVE-2020-8649 and CVE-2020-8647.
Linus pointed out that overflow checking seems absent. We're saved by
the existing bounds checks in vc_do_resize() with rather strict
limits:
if (cols > VC_RESIZE_MAXCOL || lines > VC_RESIZE_MAXROW)
return -EINVAL;

Problem:
During GU reset PSP's sysfs was being wrongly reinitilized
during call to amdgpu_device_ip_late_init which was failing
with duplicate error.
Fix:
Move psp_sysfs_init to psp_sw_init to avoid this. Add guards
in sysfs file's read and write hook agains premature call
if PSP is not finished initialization.
