c1f7fec1eb x86/speculation: Allow guests to use SSBD even if host does not
The bits set in x86_spec_ctrl_mask are used to calculate the guest's value
of SPEC_CTRL that is written to the MSR before VMENTRY, and control which
mitigations the guest can enable.  In the case of SSBD, unless the host has
enabled SSBD always on mode (by passing "spec_store_bypass_disable=on" in
the kernel parameters), the SSBD bit is not set in the mask and the guest
can not properly enable the SSBD always on mitigation mode.

This has been confirmed by running the SSBD PoC on a guest using the SSBD
always on mitigation mode (booted with kernel parameter
"spec_store_bypass_disable=on"), and verifying that the guest is vulnerable
unless the host is also using SSBD always on mode. In addition, the guest
OS incorrectly reports the SSB vulnerability as mitigated.

Always set the SSBD bit in x86_spec_ctrl_mask when the host CPU supports
it, allowing the guest to use SSBD whether or not the host has chosen to
enable the mitigation in any of its modes.

35594bc7ce pinctrl: mediatek: Ignore interrupts that are wake only during resume
Before suspending, mtk-eint would set the interrupt mask to the
one in wake_mask. However, some of these interrupts may not have a
corresponding interrupt handler, or the interrupt may be disabled.

On resume, the eint irq handler would trigger nevertheless,
and irq/pm.c:irq_pm_check_wakeup would be called, which would
try to call irq_disable. However, if the interrupt is not enabled
(irqd_irq_disabled(&desc->irq_data) is true), the call does nothing,
and the interrupt is left enabled in the eint driver.

Especially for level-sensitive interrupts, this will lead to an
interrupt storm on resume.

If we detect that an interrupt is only in wake_mask, but not in
cur_mask, we can just mask it out immediately (as mtk_eint_resume
would do anyway at a later stage in the resume sequence, when
restoring cur_mask).

b12bbdc5dd HID: intel-ish-hid: fix wrong driver_data usage
Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.

So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

The HID++ spec also defines very long HID++ reports, with a reportid of

Kyle bisected the issue to commit b569c18434 ("x86/mm/KASLR: Reduce
randomization granularity for 5-level paging to 1GB")

Before this commit PAGE_OFFSET was always aligned to P4D_SIZE when booting
5-level paging mode. But now only PUD_SIZE alignment is guaranteed.

In the case I was able to reproduce the following vaddr/paddr values were
observed in phys_p4d_init():

Iteration     vaddr			paddr
   1 	      0xff4228027fe00000 	0x033fe00000
   2	      0xff42287f40000000	0x8000000000

'vaddr' in both cases belongs to the same p4d entry.

But due to the original assumption that PAGE_OFFSET is aligned to P4D_SIZE
this overlap cannot be handled correctly. The code assumes strictly aligned
entries and unconditionally increments the index into the P4D table, which
creates false duplicate entries. Once the index reaches the end, the last
entry in the page table is missing.

Aside of that the 'paddr >= paddr_end' condition can evaluate wrong which
causes an P4D entry to be cleared incorrectly.

Change the loop in phys_p4d_init() to walk purely based on virtual
addresses like __kernel_physical_mapping_init() does. This makes it work
correctly with unaligned virtual addresses.

c1887159eb x86/boot/64: Add missing fixup_pointer() for next_early_pgt access
__startup_64() uses fixup_pointer() to access global variables in a
position-independent fashion. Access to next_early_pgt was wrapped into the
helper, but one instance in the 5-level paging branch was missed.

GCC generates a R_X86_64_PC32 PC-relative relocation for the access which
doesn't trigger the issue, but Clang emmits a R_X86_64_32S which leads to
an invalid memory access and system reboot.

81c7ed296d x86/boot/64: Fix crash if kernel image crosses page table boundary
A kernel which boots in 5-level paging mode crashes in a small percentage
of cases if KASLR is enabled.

This issue was tracked down to the case when the kernel image unpacks in a
way that it crosses an 1G boundary. The crash is caused by an overrun of
the PMD page table in __startup_64() and corruption of P4D page table
allocated next to it. This particular issue is not visible with 4-level
paging as P4D page tables are not used.

But the P4D and the PUD calculation have similar problems.

The PMD index calculation is wrong due to operator precedence, which fails
to confine the PMDs in the PMD array on wrap around.

The P4D calculation for 5-level paging and the PUD calculation calculate
the first index correctly, but then blindly increment it which causes the
same issue when a kernel image is located across a 512G and for 5-level
paging across a 46T boundary.

This wrap around mishandling was introduced when these parts moved from
assembly to C.

Restore it to the correct behaviour.

10c9c8e7c0 dm init: remove trailing newline from calls to DMERR() and DMINFO()
These printing macros already add a trailing newline, so having another
one here just makes for blank lines when these prints are enabled.
Remove these needless newlines.

ASoC: Intel: Fix race condition in IPC rx list
Since there are multiple IPCs being sent in a short span of time, there
is a possibility of more than one message being on the Rx list after
receiving response from firmware. In such cases, when the first
notification of interrupt from firmware is received, driver retrieves
the message from the Rx list but does not delete it from the list till
the next lock. In the meantime, when another interrupt is received from
the firmware, driver is reading the previous message again since the
previous message has not been removed from the list.

ALSA: hdac: Fix codec name after machine driver is unloaded and reloaded
Currently on each driver reload internal counter is being increased. It
causes failure to enumerate driver devices, as they have hardcoded:
.codec_name = "ehdaudio0D2",
As there is currently no devices with multiple hda codecs and there is
currently no established way to reliably differentiate, between them,
always assign bus->idx = 0;

This fixes a problem when we unload and reload machine driver idx gets
incremented, so .codec_name would've needed to be set to "ehdaudio1D2"
after first reload and so on.

6dbc6e6f58 pinctrl: mcp23s08: Fix add_data and irqchip_add_nested call order
Currently probing of the mcp23s08 results in an error message
"detected irqchip that is shared with multiple gpiochips:
please fix the driver"

This is due to the following:

Call to mcp23s08_irqchip_setup() with call hierarchy:
mcp23s08_irqchip_setup()
  gpiochip_irqchip_add_nested()
    gpiochip_irqchip_add_key()
      gpiochip_set_irq_hooks()

Call to devm_gpiochip_add_data() with call hierarchy:
devm_gpiochip_add_data()
  gpiochip_add_data_with_key()
    gpiochip_add_irqchip()
      gpiochip_set_irq_hooks()

The gpiochip_add_irqchip() returns immediately if there isn't a irqchip
but we added a irqchip due to the previous mcp23s08_irqchip_setup()
call. So it calls gpiochip_set_irq_hooks() a second time.

Fix this by moving the call to devm_gpiochip_add_data before
the call to mcp23s08_irqchip_setup

Additionally the lines regarding SSID 0x96e1 and 0x97e1 didn't fix audio for the

ALC1220_FIXP_CLEVO_PB51ED_PINS swapped pins that are not necesarry to be
