aa4113340a powerpc/fsl_booke: Avoid creating duplicate tlb1 entry
In the current implementation, the call to loadcam_multi() is wrapped
between switch_to_as1() and restore_to_as0() calls so, when it tries
to create its own temporary AS=1 TLB1 entry, it ends up duplicating
the existing one created by switch_to_as1(). Add a check to skip
creating the temporary entry if already running in AS=1.

3670664b5d tty: evh_bytechan: Fix out of bounds accesses
ev_byte_channel_send() assumes that its third argument is a 16 byte
array. Some places where it is called it may not be (or we can't
easily tell if it is). Newer compilers have started producing warnings
about this, so make sure we actually pass a 16 byte array.

There may be more elegant solutions to this, but the driver is quite
old and hasn't been updated in many years.

The warnings (from a powerpc allyesconfig build) are:

4f41fe386a clocksource/drivers/timer-probe: Avoid creating dead devices
Timer initialization is done during early boot way before the driver
core starts processing devices and drivers. Timers initialized during
this early boot period don't really need or use a struct device.

However, for timers represented as device tree nodes, the struct devices
are still created and sit around unused and wasting memory. This change
avoid this by marking the device tree nodes as "populated" if the
corresponding timer is successfully initialized.

e48667b865 perf/amd/uncore: Add support for Family 19h L3 PMU
Family 19h introduces change in slice, core and thread specification in
its L3 Performance Event Select (ChL3PmcCfg) h/w register. The change is
incompatible with Family 17h's version of the register.

Introduce a new path in l3_thread_slice_mask() to do things differently
for Family 19h vs. Family 17h, otherwise the new hardware doesn't get
programmed correctly.

Instead of a linear core--thread bitmask, Family 19h takes an encoded
core number, and a separate thread mask. There are new bits that are set
for all cores and all slices, of which only the latter is used, since
the driver counts events for all slices on behalf of the specified CPU.

Also update amd_uncore_init() to base its L2/NB vs. L3/Data Fabric mode
decision based on Family 17h or above, not just 17h and 18h: the Family
19h Data Fabric PMC is compatible with the Family 17h DF PMC.

b27e35f91c staging: mt7621-pci: use gpios for properly reset
Original driver code was using three gpio's for reset
asserts and deasserts the pcis. Instead of using that
a general reset control with a perst gpio was introduced
and it seems it is partially working but sometimes there
are some unexpected hangs on boot. This commit make use of
the three original gpios using 'reset-gpios' property of
the device tree and removes the reset line and perst gpio.
According to the mediatek aplication note v0.1 there are
three gpios used for pcie ports reset control: gpio#19,
gpio#8 and gpio#7 for slots 0, 1 and 2 respectively.
This schema can be used separately for mt7621A but in some
boards due to pin share issue, if the PCM and I2S function
are enable at the same time, there are no enough GPIO to
control per-port PCIe reset. In those cases gpio#19 is enought
for reset the three ports together. Because of this we just
try to get the three gpios but if some of them fail we are not
failing in boot process, just prints a kernel notice and take
after into account if the descriptor is or not valid in order
to use it. All of them are set as GPIO output low configuration.
The gpio descriptor's API takes device tree property into account
and invert value if the pin is configured as active low.
So we also have to properly request pins from device tree
and set values correct in assert and deassert functions.
After this changes the order to make all assert and
deassert in the 'probe' process makes more sense:
* Parse device tree.
* make assert of the RC's and EP's before doing anything else.
* make deassert of the RC's before initializing the phy.
* Init the phy.
* make deassert of the EP's before initialize pci ports.
* Normal PCI initialization.

d8dd36459d staging: vt6656: Use BIT_ULL() macro instead of bit shift operation
Replace the bit left shift operation with the BIT_ULL() macro and remove
the unnecessary mask off operation against the bit_nr variable.

This mask is only there for legacy reasons. Originally it was 31 (0x1f)
and the bit_nr variable spread across an mc_filter array with two u32
elements. Now, this mask is not needed because its value is 0x3f and the
mc_filter variable is an u64 type.

In this situation, the 26 bit right shift operation against the value
returned by the ether_crc function set the bit_nr variable to the
following value:

bit 31 to bit 6 -> All 0 (due to the bit shift operation happens over an
unsigned type).

bit 5 to bit 0 -> The 6 msb bits of the value returned by the ether_crc
function.

The purpose of the 0x3f mask against the bit_nr variable is to reset
(set to 0) the 26 msb bits (bit 31 to bit 6), but these bits are yet 0.
So, the mask off operation is now unnecessary.

The SDHCI_PRESET_FOR_* registers are not set for the UniPhier platform
integration. (They are all read as zeros).

Set the SDHCI_QUIRK2_PRESET_VALUE_BROKEN quirk flag. Otherwise, the
High Speed DDR mode on the eMMC controller (MMC_TIMING_MMC_DDR52)
would not work.

I split the platform data to give no impact to other platforms,
although the UniPhier platform is currently only the upstream user
of this IP.

The SDHCI_QUIRK2_PRESET_VALUE_BROKEN flag is set if the compatible
string matches to "socionext,uniphier-sd4hc".

84d49b3d08 mmc: sdhci-acpi: Switch signal voltage back to 3.3V on suspend on external microSD on Lenovo Miix 320
Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288
PMIC depending on the design one of 2 possible LDOs on the PMIC is used
for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in
low noise LDO mode).

The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM
methods to set 3.3 or 1.8 signalling voltage and this appears to work
as advertised, so presumably the device is actually using GPIO1LDO for
the external microSD signalling voltage.

But this device has a bug in the _PS0 method of the SHC1 ACPI device,
the DSM remembers the last set signalling voltage and the _PS0 restores
this after a (runtime) suspend-resume cycle, but it "restores" the voltage
on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3
is used for the LCD and setting it to 1.8V causes the LCD to go black.

This commit works around this issue by calling the Intel DSM to reset the
signal voltage to 3.3V after the host has been runtime suspended.
This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which
leaves it at its original setting fixing the LCD going black.

This commit adds and uses a DMI quirk mechanism to only trigger this
workaround on the Lenovo Miix 320 while leaving the behavior of the
driver unchanged on other devices.

17c4a2ae15 dma-mapping: Fix dma_pgprot() for unencrypted coherent pages
When dma_mmap_coherent() sets up a mapping to unencrypted coherent memory
under SEV encryption and sometimes under SME encryption, it will actually
set up an encrypted mapping rather than an unencrypted, causing devices
that DMAs from that memory to read encrypted contents. Fix this.

When force_dma_unencrypted() returns true, the linear kernel map of the
coherent pages have had the encryption bit explicitly cleared and the
page content is unencrypted. Make sure that any additional PTEs we set
up to these pages also have the encryption bit cleared by having
dma_pgprot() return a protection with the encryption bit cleared in this
case.

6db73f17c5 x86: Don't let pgprot_modify() change the page encryption bit
When SEV or SME is enabled and active, vm_get_page_prot() typically
returns with the encryption bit set. This means that users of
pgprot_modify(, vm_get_page_prot()) (mprotect_fixup(), do_mmap()) end up
with a value of vma->vm_pg_prot that is not consistent with the intended
protection of the PTEs.

This is also important for fault handlers that rely on the VMA
vm_page_prot to set the page protection. Fix this by not allowing
pgprot_modify() to change the encryption bit, similar to how it's done
for PAT bits.

supports display port emulation, not DVI or HDMI. This patch fixes this
