commit 5a91206ff0 upstream.
When saa7134 module driving a Medion 7134 card is reloaded reads of this
card EEPROM (required for automatic detection of tuner model) will be
corrupted due to I2C gate in DVB-T demod being left closed.
This sometimes also happens on first saa7134 module load after a warm
reboot.
Fix this by opening this I2C gate before doing EEPROM read during i2c
initialization.

commit 42cfcafb91 upstream.
Changes in the SW cts (ciphertext stealing) code in
commit 0605c41cc5 ("crypto: cts - Convert to skcipher")
revealed a problem in the CAAM driver:
when cts(cbc(aes)) is executed and cts runs in SW,
cbc(aes) is offloaded in CAAM; cts encrypts the last block
in atomic context and CAAM incorrectly decides to use GFP_KERNEL
for memory allocation.
Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is
set, i.e. remove MAY_BACKLOG flag.
We split the fix in two parts - first is sent to -stable, while the
second is not (since there is no known failure case).

There is a clean-up bug in the core comedi module initialization
functions, `comedi_init()`. If the `comedi_num_legacy_minors` module
parameter is non-zero (and valid), it creates that many "legacy" devices
and registers them in SysFS. A failure causes the function to clean up
and return an error. Unfortunately, it fails to destroy the "comedi"
class that was created earlier. Fix it by adding a call to
`class_destroy(comedi_class)` at the appropriate place in the clean-up
sequence.

commit d1bd4a792d upstream.
If a TPM2 loses power without a TPM2_Shutdown command being issued (a
"disorderly reboot"), it may lose some state that has yet to be
persisted to NVRam, and will increment the DA counter. After the DA
counter gets sufficiently large, the TPM will lock the user out.
NOTE: This only changes behavior on TPM2 devices. Since TPM1 uses sysfs,
and sysfs relies on implicit locking on chip->ops, it is not safe to
allow this code to run in TPM1, or to add sysfs support to TPM2, until
that locking is made explicit.

commit da6c2addf6 upstream.
To set the mux mode of a pin two bits must be set. Up to now this is
implemented using the following idiom:
writel(mask, reg + CLR);
writel(value, reg + SET);
. This however results in the mux mode being 0 between the two writes.
On my machine there is an IC's reset pin connected to LCD_D20. The
bootloader configures this pin as GPIO output-high (i.e. not holding the
IC in reset). When Linux reconfigures the pin to GPIO the short time
LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse
the connected IC.
The same problem is present for the pin's drive strength setting which is
reset to low drive strength before using the right value.
So instead of relying on the hardware to modify the register setting
using two writes implement the bit toggling using read-modify-write.

commit 7036502783 upstream.
After commit 47c950d102 ("pinctrl: cherryview: Do not add all
southwest and north GPIOs to IRQ domain") the driver does not add all
GPIOs to the irqdomain. The reason for that is that those GPIOs cannot
generate IRQs at all, only GPEs (General Purpose Events). This causes
Linux virtual IRQ numbering to change.
However, it seems some CYAN Chromebooks, including Acer Chromebook
hardcodes these Linux IRQ numbers in the ACPI tables of the machine.
Since the numbering is different now, the IRQ meant for keyboard does
not match the Linux virtual IRQ number anymore making the keyboard
non-functional.
Work this around by adding special quirk just for these machines where
we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell
based machines will not be affected by the change.

commit 77c0d0cd10 upstream.
Our code was assigning number of channels to the index variable by
default. If firmware reported channel we didn't predict this would
result in using that initial index value and writing out of array. This
never happened so far (we got a complete list of supported channels) but
it means possible memory corruption so we should handle it anyway.
This patch simply detects unexpected channel and ignores it.
As we don't try to create new entry now, it's also safe to drop hw_value
and center_freq assignment. For known channels we have these set anyway.
I decided to fix this issue by assigning NULL or a target channel to the
channel variable. This was one of possible ways, I prefefred this one as
it also avoids using channel[index] over and over.

Also, the guest_mode bit should be set and cleared only when
SVM updates posted-interrupt interrupt remapping information.

commit 73dbd4a423 upstream.
In function amd_iommu_bind_pasid(), the control flow jumps
to label out_free when pasid_state->mm and mm is NULL. And
mmput(mm) is called. In function mmput(mm), mm is
referenced without validation. This will result in a NULL
dereference bug. This patch fixes the bug.

commit 938f1bbe35 upstream.
Even if a host controller's CPU-side MMIO windows into PCI I/O space do
happen to leak into PCI memory space such that it might treat them as
peer addresses, trying to reserve the corresponding I/O space addresses
doesn't do anything to help solve that problem. Stop doing a silly thing.

commit 797a8b4d76 upstream.
We wouldn't normally expect ops->attach_dev() to fail, but on IOMMUs
with limited hardware resources, or generally misconfigured systems,
it is certainly possible. We report failure correctly from the external
iommu_attach_device() interface, but do not do so in iommu_group_add()
when attaching to the default domain. The result of failure there is
that the device, group and domain all get left in a broken,
part-configured state which leads to weird errors and misbehaviour down
the line when IOMMU API calls sort-of-but-don't-quite work.
Check the return value of __iommu_attach_device() on the default domain,
and refactor the error handling paths to cope with its failure and clean
up correctly in such cases.

commit f7116e115a upstream.
dma_pte_free_level() recurses down the IOMMU page tables and frees
directory pages that are entirely contained in the given PFN range.
Unfortunately, it incorrectly calculates the starting address covered
by the PTE under consideration, which can lead to it clearing an entry
that is still in use.
This occurs if we have a scatterlist with an entry that has a length
greater than 1026 MB and is aligned to 2 MB for both the IOMMU and
physical addresses. For example, if __domain_mapping() is asked to map a
two-entry scatterlist with 2 MB and 1028 MB segments to PFN 0xffff80000,
it will ask if dma_pte_free_pagetable() is asked to PFNs from
0xffff80200 to 0xffffc05ff, it will also incorrectly clear the PFNs from
0xffff80000 to 0xffff801ff because of this issue. The current code will
set level_pfn to 0xffff80200, and 0xffff80200-0xffffc01ff fits inside
the range being cleared. Properly setting the level_pfn for the current
level under consideration catches that this PTE is outside of the range
being cleared.
This patch also changes the value passed into dma_pte_free_level() when
it recurses. This only affects the first PTE of the range being cleared,
and is handled by the existing code that ensures we start our cursor no
lower than start_pfn.
This was found when using dma_map_sg() to map large chunks of contiguous
memory, which immediatedly led to faults on the first access of the
erroneously-deleted mappings.
