Brian Norris 57347363de drm/panel: Delete panel on mipi_dsi_attach() failure
[ Upstream commit 9bf7123bb0 ]

Many DSI panel drivers fail to clean up their panel references on
mipi_dsi_attach() failure, so we're leaving a dangling drm_panel
reference to freed memory. Clean that up on failure.

Noticed by inspection, after seeing similar problems on other drivers.
Therefore, I'm not marking Fixes/stable.

hci_alloc_dev() do not init the device's flag. And hci_free_dev()
using put_device() to free the memory allocated for this device,
but it calls just put_device(dev) only in case of HCI_UNREGISTER
flag is set, So any error handing before hci_register_dev() success
will cause memory leak.

To avoid this behaviour we can using kfree() to release dev before
hci_register_dev() success.

[ Upstream commit 9e87a8da74 ]

Commit a5d3d1adc9 ("leds: lp55xx: Initialize enable GPIO direction to

for the Nokia N900 the value needs to be set to HIGH, per the device
tree. So rather than hardcoding the value to a potentially invalid value
for some devices, let's set direction in lp55xx_init_device.

Stephen Boyd c19b9b7554 of/fdt: Don't worry about non-memory region overlap for no-map
[ Upstream commit da17d6905d ]

In commit 8a5a75e5e9 ("of/fdt: Make sure no-map does not remove
already reserved regions") we returned -EBUSY when trying to mark
regions as no-map when they intersect with reserved memory. The goal was
to find bad no-map reserved memory DT nodes that would unmap the kernel
text/data sections.

The problem is the reserved memory check will still trigger if the DT
has a /memreserve/ that completely subsumes the no-map memory carveouts
in the reserved memory node _and_ that region is also not part of the
memory reg property. For example in sc7180.dtsi we have the following
reserved-memory and memory node:

      memory@80000000 {
          /* We expect the bootloader to fill in the size */
          reg = <0 0x80000000 0 0>;
      };

      smem_mem: memory@80900000 {
              reg = <0x0 0x80900000 0x0 0x200000>;
              no-map;
      };

and the memreserve filled in by the bootloader is

      /memreserve/ 0x80800000 0x400000;

while the /memory node is transformed into

      memory@80000000 {
          /* The bootloader fills in the size, and adds another region */
          reg = <0 0x80000000 0 0x00800000>,
                <0 0x80c00000 0 0x7f200000>;
      };

The smem region is doubly reserved via /memreserve/ and by not being
part of the /memory reg property. This leads to the following warning
printed at boot.

 OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB

Otherwise nothing really goes wrong because the smem region is not going
to be mapped by the kernel's direct linear mapping given that it isn't
part of the memory node. Therefore, let's only consider this to be a
problem if we're trying to mark a region as no-map and it is actually
memory that we're intending to keep out of the kernel's direct mapping
but it's already been reserved.

- in bm1880_clk_register_plls this is pointed to an element of arg1:

The MIPS BMC63XX subarch does not provide/support clk_set_parent().
This causes build errors in a few drivers, so add a simple implementation
of that function so that callers of it will build without errors.

Trevor Wu 78926da033 ASoC: mediatek: mt8195: correct pcmif BE dai control flow
[ Upstream commit 2355028c0c ]

Originally, the conditions for preventing reentry are not correct.
dai->component->active is not the state specifically for pcmif dai, so it
is not a correct condition to indicate the status of pcmif dai.
On the other hand, snd_soc_dai_stream_actvie() in prepare ops for both
playback and capture possibly return true at the first entry when these
two streams are opened at the same time.

In the patch, I refer to the implementation in mt8192-dai-pcm.c.
Clock and enabling bit for PCMIF are managed by DAPM, and the condition
for prepare ops is replaced by the status of dai widget.

Michael Ellerman fca58a4344 powerpc/64s: Use EMIT_WARN_ENTRY for SRR debug warnings
[ Upstream commit fd1eaaaaa6 ]

When CONFIG_PPC_RFI_SRR_DEBUG=y we check the SRR values before returning
from interrupts. This is done in asm using EMIT_BUG_ENTRY, and passing
BUGFLAG_WARNING.

However that fails to create an exception table entry for the warning,
and so do_program_check() fails the exception table search and proceeds
to call _exception(), resulting in an oops like:

We should instead use EMIT_WARN_ENTRY, which creates an exception table
entry for the warning, allowing the warning to be correctly recognised,
and the code to resume after printing the warning.

Note however that because this warning is buried deep in the interrupt
return path, we are not able to recover from it (due to MSR_RI being
clear), so we still end up in die() with an unrecoverable exception.

Alan Stern af8cab36bf scsi: block: pm: Always set request queue runtime active in blk_post_runtime_resume()
[ Upstream commit 6e1fcab00a ]

John Garry reported a deadlock that occurs when trying to access a
runtime-suspended SATA device.  For obscure reasons, the rescan procedure
causes the link to be hard-reset, which disconnects the device.

The rescan tries to carry out a runtime resume when accessing the device.
scsi_rescan_device() holds the SCSI device lock and won't release it until
it can put commands onto the device's block queue.  This can't happen until
the queue is successfully runtime-resumed or the device is unregistered.
But the runtime resume fails because the device is disconnected, and
__scsi_remove_device() can't do the unregistration because it can't get the
device lock.

The best way to resolve this deadlock appears to be to allow the block
queue to start running again even after an unsuccessful runtime resume.
The idea is that the driver or the SCSI error handler will need to be able
to use the queue to resolve the runtime resume failure.

This patch removes the err argument to blk_post_runtime_resume() and makes
the routine act as though the resume was successful always.  This fixes the
deadlock.

This bug introduced by commit b261dba2fd ("arm64: kdump: Remove custom
linux,usable-memory-range handling"), which moves
memblock_cap_memory_range() to fdt, but it breaches the rules that
memblock_cap_memory_range() should come after memblock_add() etc as said
in commit e888fa7bb8 ("memblock: Check memory add/cap ordering").

As a consequence, the virtual address set up by copy_oldmem_page() does
not bail out from the test of virt_addr_valid() in check_heap_object(),
and finally hits the BUG_ON().

Since memblock allocator has no idea about when the memblock is fully
populated, while efi_init() is aware, so tackling this issue by calling the
interface early_init_dt_check_for_usable_mem_range() exposed by of/fdt.

domain's flush queue has drained naturally. At this point, it is then
possible for the timeout to expire just before the del_timer() call
in free_iova_flush_queue(), such that we then proceed to free the FQ
resources while fq_flush_timeout() is still accessing them on another
CPU. Crashes due to this have been observed in the wild while removing
NVMe devices.

Close the race window by using del_timer_sync() to safely wait for any
active timeout handler to finish before we start to free things. We
already avoid any locking in free_iova_flush_queue() since the FQ is
supposed to be inactive anyway, so the potential deadlock scenario does
not apply.

Maxim Levitsky 7e7e12092a iommu/amd: X2apic mode: mask/unmask interrupts on suspend/resume
[ Upstream commit 1980105e3c ]

Use IRQCHIP_MASK_ON_SUSPEND to make the core irq code to
mask the iommu interrupt on suspend and unmask it on the resume.

Since now the unmask function updates the INTX settings,
that will restore them on resume from s3/s4.

Since IRQCHIP_MASK_ON_SUSPEND is only effective for interrupts
which are not wakeup sources, remove IRQCHIP_SKIP_SET_WAKE flag
and instead implement a dummy .irq_set_wake which doesn't allow
the interrupt to become a wakeup source.

Lukas Bulwahn b1f6595977 mips: fix Kconfig reference to PHYS_ADDR_T_64BIT
[ Upstream commit a670c82d9c ]

Commit d4a451d5fc ("arch: remove the ARCH_PHYS_ADDR_T_64BIT config
symbol") removes config ARCH_PHYS_ADDR_T_64BIT with all instances of that
config refactored appropriately. Since then, it is recommended to use the
config PHYS_ADDR_T_64BIT instead.

Commit 171543e752 ("MIPS: Disallow CPU_SUPPORTS_HUGEPAGES for XPA,EVA")
introduces the expression "!(32BIT && (ARCH_PHYS_ADDR_T_64BIT || EVA))"
for config CPU_SUPPORTS_HUGEPAGES, which unintentionally refers to the
non-existing symbol ARCH_PHYS_ADDR_T_64BIT instead of the intended
PHYS_ADDR_T_64BIT.

Fix this Kconfig reference to the intended PHYS_ADDR_T_64BIT.

This issue was identified with the script ./scripts/checkkconfigsymbols.py.
I then reported it on the mailing list and Paul confirmed the mistake in
the linked email thread.

Lukas Bulwahn f345281019 mips: add SYS_HAS_CPU_MIPS64_R5 config for MIPS Release 5 support
[ Upstream commit fd4eb90b16 ]

Commit ab7c01fdc3 ("mips: Add MIPS Release 5 support") adds the two
configs CPU_MIPS32_R5 and CPU_MIPS64_R5, which depend on the corresponding
SYS_HAS_CPU_MIPS32_R5 and SYS_HAS_CPU_MIPS64_R5, respectively.

The config SYS_HAS_CPU_MIPS32_R5 was already introduced with commit
c5b367835c ("MIPS: Add support for XPA."); the config
SYS_HAS_CPU_MIPS64_R5, however, was never introduced.

Hence, ./scripts/checkkconfigsymbols.py warns:

  SYS_HAS_CPU_MIPS64_R5
  Referencing files: arch/mips/Kconfig, arch/mips/include/asm/cpu-type.h

Add the definition for config SYS_HAS_CPU_MIPS64_R5 under the assumption
that SYS_HAS_CPU_MIPS64_R5 follows the same pattern as the existing
SYS_HAS_CPU_MIPS32_R5 and SYS_HAS_CPU_MIPS64_R6.
