[ Upstream commit 20c2dbff342aec13bf93c2f6c951da198916a455 ]
Apparently some BXT/GLK systems have DSI panels whose timings
don't agree with the normal cpu transcoder hblank>=32 limitation.
This is perhaps fine as there are no specific hblank/etc. limits
listed for the BXT/GLK DSI transcoders.
Move those checks out from the global intel_mode_valid() into
into connector specific .mode_valid() hooks, skipping BXT/GLK
DSI connectors. We'll leave the basic [hv]display/[hv]total
checks in intel_mode_valid() as those seem like sensible upper
limits regardless of the transcoder used.

commit edc0378eee00200a5bedf1bb9f00ad390e0d1bd4 upstream.
There are some Loongson64 systems come with broken coherent DMA
support, firmware will set a bit in boot_param and pass nocoherentio
in cmdline.
However nonconherent support was missed out when spin off Loongson-2EF
form Loongson64, and that boot_param change never made itself into
upstream.
Support DMA noncoherent properly to get those systems working.

commit c7206e7bd214ebb3ca6fa474a4423662327d9beb upstream.
There are many types of revsered memory passed from firmware
that should be reserved in memblock, and UMA memory passed
from firmware that should be added to system memory for system
to use.
Also for memblock there is no need to align those space into page,
which actually cause problems.

commit 8f7aa77a463f47c9e00592d02747a9fcf2271543 upstream.
vgabios is passed from firmware to kernel on Loongson64 systems.
Sane firmware will keep this pointer in reserved memory space
passed from the firmware but insane firmware keeps it in low
memory before kernel entry that is not reserved.
Previously kernel won't try to allocate memory from low memory
before kernel entry on boot, but after converting to memblock
it will do that.
Fix by resversing those memory on early boot.

commit 4cdf351d3630a640ab6a05721ef055b9df62277f upstream.
In general, activating long mode involves setting the EFER_LME bit in
the EFER register and then enabling the X86_CR0_PG bit in the CR0
register. At this point, the EFER_LMA bit will be set automatically by
hardware.
In the case of SVM/SEV guests where writes to CR0 are intercepted, it's
necessary for the host to set EFER_LMA on behalf of the guest since
hardware does not see the actual CR0 write.
In the case of SEV-ES guests where writes to CR0 are trapped instead of
intercepted, the hardware *does* see/record the write to CR0 before
exiting and passing the value on to the host, so as part of enabling
SEV-ES support commit f1c6366e3043 ("KVM: SVM: Add required changes to
support intercepts under SEV-ES") dropped special handling of the
EFER_LMA bit with the understanding that it would be set automatically.
However, since the guest never explicitly sets the EFER_LMA bit, the
host never becomes aware that it has been set. This becomes problematic
when userspace tries to get/set the EFER values via
KVM_GET_SREGS/KVM_SET_SREGS, since the EFER contents tracked by the host
will be missing the EFER_LMA bit, and when userspace attempts to pass
the EFER value back via KVM_SET_SREGS it will fail a sanity check that
asserts that EFER_LMA should always be set when X86_CR0_PG and EFER_LME
are set.
Fix this by always inferring the value of EFER_LMA based on X86_CR0_PG
and EFER_LME, regardless of whether or not SEV-ES is enabled.

commit c54fc3a4f375663f2361a9cbb2955fb4ef912879 upstream.
Fix a number of issues in the cifs filesystem implementation of the FICLONE
ioctl in cifs_remap_file_range(). This is analogous to the previously
fixed bug in cifs_file_copychunk_range() and can share the helper
functions.
Firstly, the invalidation of the destination range is handled incorrectly:
We shouldn't just invalidate the whole file as dirty data in the file may
get lost and we can't just call truncate_inode_pages_range() to invalidate
the destination range as that will erase parts of a partial folio at each
end whilst invalidating and discarding all the folios in the middle. We
need to force all the folios covering the range to be reloaded, but we
mustn't lose dirty data in them that's not in the destination range.
Further, we shouldn't simply round out the range to PAGE_SIZE at each end
as cifs should move to support multipage folios.
Secondly, there's an issue whereby a write may have extended the file
locally, but not have been written back yet. This can leaves the local
idea of the EOF at a later point than the server's EOF. If a clone request
is issued, this will fail on the server with STATUS_INVALID_VIEW_SIZE
(which gets translated to -EIO locally) if the clone source extends past
the server's EOF.
Fix this by:
(0) Flush the source region (already done). The flush does nothing and
the EOF isn't moved if the source region has no dirty data.
(1) Move the EOF to the end of the source region if it isn't already at
least at this point. If we can't do this, for instance if the server
doesn't support it, just flush the entire source file.
(2) Find the folio (if present) at each end of the range, flushing it and
increasing the region-to-be-invalidated to cover those in their
entirety.
(3) Fully discard all the folios covering the range as we want them to be
reloaded.
(4) Then perform the extent duplication.
Thirdly, set i_size after doing the duplicate_extents operation as this
value may be used by various things internally. stat() hides the issue
because setting ->time to 0 causes cifs_getatr() to revalidate the
attributes.
These were causing the cifs/001 xfstest to fail.

commit 9b8493dc43044376716d789d07699f17d538a7c4 upstream.
Commit in Fixes added an AMD-specific microcode callback. However, it
didn't check the CPU vendor the kernel runs on explicitly.
The only reason the Zenbleed check in it didn't run on other x86 vendors
hardware was pure coincidental luck:
if (!cpu_has_amd_erratum(c, amd_zenbleed))
return;
gives true on other vendors because they don't have those families and
models.
However, with the removal of the cpu_has_amd_erratum() in
05f5f73936fa ("x86/CPU/AMD: Drop now unused CPU erratum checking function")
that coincidental condition is gone, leading to the zenbleed check
getting executed on other vendors too.
Add the explicit vendor check for the whole callback as it should've
been done in the first place.

commit af54d778a03853801d681c98c0c2a6c316ef9ca7 upstream.
dev_coredumpm() creates a devcoredump device and adds it
to the core kernel framework which eventually end up
sending uevent to the user space and later creates a
symbolic link to the failed device. An application
running in userspace may be interested in this symbolic
link to get the name of the failed device.
In a issue scenario, once uevent sent to the user space
it start reading '/sys/class/devcoredump/devcdX/failing_device'
to get the actual name of the device which might not been
created and it is in its path of creation.
To fix this, suppress sending uevent till the failing device
symbolic link gets created and send uevent once symbolic
link is created successfully.

commit 08ce9a1b72e38cf44c300a44ac5858533eb3c860 upstream.
This device has a silicon bug that makes it report a timeout interrupt
but no data in the FIFO.
The datasheet states the following in the errata section 18.1.4:
"If the host reads the receive FIFO at the same time as a
time-out interrupt condition happens, the host might read 0xCC
(time-out) in the Interrupt Indication Register (IIR), but bit 0
of the Line Status Register (LSR) is not set (means there is no
data in the receive FIFO)."
The errata description seems to indicate it concerns only polled mode of
operation when reading bit 0 of the LSR register. However, tests have
shown and NXP has confirmed that the RXLVL register also yields 0 when
the bug is triggered, and hence the IRQ driven implementation in this
driver is equally affected.
This bug has hit us on production units and when it does, sc16is7xx_irq()
would spin forever because sc16is7xx_port_irq() keeps seeing an
interrupt in the IIR register that is not cleared because the driver
does not call into sc16is7xx_handle_rx() unless the RXLVL register
reports at least one byte in the FIFO.
Fix this by always reading one byte from the FIFO when this condition
is detected in order to clear the interrupt. This approach was
confirmed to be correct by NXP through their support channels.

commit 58ac1b3799799069d53f5bf95c093f2fe8dd3cc5 upstream.
Since there is no guarantee that the memory returned by
dma_alloc_coherent() is associated with a 'struct page', using the
architecture specific phys_to_page() is wrong, but using
virt_to_page() would be as well.
Stop using sg lists altogether and just use the *_single() functions
instead. This also simplifies the code a bit since the scatterlists in
this driver always have only one entry anyway.

commit b17b7fe6dd5c6ff74b38b0758ca799cdbb79e26e upstream.
When typec_altmode_put_partner is called by a plug altmode upon release,
the port altmode the plug belongs to will not remove its reference to the
plug. The check to see if the altmode being released evaluates against the
released altmode's partner instead of the calling altmode itself, so change
adev in typec_altmode_put_partner to properly refer to the altmode being
released.
typec_altmode_set_partner is not run for port altmodes, so also add a check
in typec_altmode_release to prevent typec_altmode_put_partner() calls on
port altmode release.

commit 92414333eb375ed64f4ae92d34d579e826936480 upstream.
If server returned no data for FSCTL_DFS_GET_REFERRALS, @dfs_rsp will
remain NULL and then parse_dfs_referrals() will dereference it.
Fix this by returning -EIO when no output data is returned.
Besides, we can't fix it in SMB2_ioctl() as some FSCTLs are allowed to
return no data as per MS-SMB2 2.2.32.

commit 24be0b3c40594a14b65141ced486ae327398faf8 upstream.
This reverts commit 4baf1218150985ee3ab0a27220456a1f027ea0ac.
Enabling runtime pm as default for all AMD xHC 1.1 controllers caused
regression. An initial attempt to fix those was done in commit a5d6264b638e
("xhci: Enable RPM on controllers that support low-power states") but new
issues are still seen.
Revert this to get those AMD xHC 1.1 systems working
This patch went to stable an needs to be reverted from there as well.

commit 691a41d8da4b34fe72f09393505f55f28a8f34ec upstream.
Deduplication isn't supported on cifs, but cifs doesn't reject it, instead
treating it as extent duplication/cloning. This can cause generic/304 to go
silly and run for hours on end.
Fix cifs to indicate EOPNOTSUPP if REMAP_FILE_DEDUP is set in
->remap_file_range().
Note that it's unclear whether or not commit b073a08016a1 is meant to cause
cifs to return an error if REMAP_FILE_DEDUP.

Reverse device managed memory allocation for the report descriptor
to fix the issue.
Tested:
This change was tested on the AMD EthanolX CRB server with the BMC
based on the OpenBMC distribution. The BMC provides KVM functionality
via the USB gadget device:
- before: KVM page refresh results in a broken USB device,
- after: KVM page refresh works without any issues.

definition names to the address they set, not the chip they attach

[ Upstream commit 95dd1e34ff5bbee93a28ff3947eceaf6de811b1a ]
If gpio_set_transitory() fails, we should free the GPIO again. Most
notably, the flag FLAG_REQUESTED has previously been set in
gpiod_request_commit(), and should be reset on failure.
To my knowledge, this does not affect any current users, since the
gpio_set_transitory() mainly returns 0 and -ENOTSUPP, which is converted
to 0. However the gpio_set_transitory() function calles the .set_config()
function of the corresponding GPIO chip and there are some GPIO drivers in
which some (unlikely) branches return other values like -EPROBE_DEFER,
and -EINVAL. In these cases, the above mentioned FLAG_REQUESTED would not
be reset, which results in the pin being blocked until the next reboot.

A write-access violation page fault kernel crash was observed while running
cpuhotplug LTP testcases on SEV-ES enabled systems. The crash was
observed during hotplug, after the CPU was offlined and the process
was migrated to different CPU. setup_ghcb() is called again which
tries to update ghcb_version in sev_es_negotiate_protocol(). Ideally this
is a read_only variable which is initialised during booting.
Trying to write it results in a pagefault:
