Since I wrote the below patch if you run a debug kernel you can a
dma debug warning like:
nouveau 0000:1f:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address=0x000000016e012000] [size=4096 bytes]
The old nouveau code wasn't consolidate the pages like the ttm code,
but the dma-debug expects the sync code to give it the same base/range
pairs as the allocator.
Fix the nouveau sync code to consolidate pages before calling the
sync code.
Fixes: bd549d35b4 ("nouveau: use ttm populate mapping functions. (v2)")

When the host sends multiple h2cdata PDUs, we keep track on
the receive progress and calculate the scatterlist index and
offsets.
The issue is that sg_offset should only be kept for the first
iov entry we map in the iovec as this is the difference between
our cursor and the sg entry offset itself.
In addition, the sg index was calculated wrong because we should
not round up when dividing the command byte offset with PAG_SIZE.

xhci driver may in some special cases need to copy small amounts
of payload data to a bounce buffer in order to meet the boundary
and alignment restrictions set by the xHCI specification.
In the majority of these cases the data is in a sg list, and
driver incorrectly assumed data is always in urb->sg when using
the bounce buffer.
If data instead is contiguous, and in urb->transfer_buffer, we may still
need to bounce buffer a small part if data starts very close (less than
packet size) to a 64k boundary.
Check if sg list is used before copying data to/from it.

Older ATF does not provide SMC call for USB 3.0 phy power on functionality
and therefore initialization of xhci-hcd is failing when older version of
ATF is used. In this case phy_power_on() function returns -EOPNOTSUPP.
[ 3.108467] mvebu-a3700-comphy d0018300.phy: unsupported SMC call, try updating your firmware
[ 3.117250] phy phy-d0018300.phy.0: phy poweron failed --> -95
[ 3.123465] xhci-hcd: probe of d0058000.usb failed with error -95
This patch introduces a new plat_setup callback for xhci platform drivers
which is called prior calling usb_add_hcd() function. This function at its
beginning skips PHY init if hcd->skip_phy_initialization is set.
Current init_quirk callback for xhci platform drivers is called from
xhci_plat_setup() function which is called after chip reset completes.
It happens in the middle of the usb_add_hcd() function and therefore this
callback cannot be used for setting if PHY init should be skipped or not.
For Armada 3720 this patch introduce a new xhci_mvebu_a3700_plat_setup()
function configured as a xhci platform plat_setup callback. This new
function calls phy_power_on() and in case it returns -EOPNOTSUPP then
XHCI_SKIP_PHY_INIT quirk is set to instruct xhci-plat to skip PHY
initialization.
This patch fixes above failure by ignoring 'not supported' error in
xhci-hcd driver. In this case it is expected that phy is already power on.
It fixes initialization of xhci-hcd on Espressobin boards where is older
Marvell's Arm Trusted Firmware without SMC call for USB 3.0 phy power.
This is regression introduced in commit bd3d25b073 ("arm64: dts: marvell:
armada-37xx: link USB hosts with their PHYs") where USB 3.0 phy was defined
and therefore xhci-hcd on Espressobin with older ATF started failing.

This reverts commit c17e9377aa.
The lpc32xx clock driver is not able to actually change the PLL rate as
this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK,
then stop the PLL, update the register, restart the PLL and wait for the
PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK
PLL.
Currently, the HCLK driver simply updates the registers but this has no
real effect and all the clock rate calculation end up being wrong. This is
especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

BPi Pro needs TX and RX delay for Gbit to work reliable and avoid high
packet loss rates. The realtek phy driver overrides the settings of the
pull ups for the delays, so fix this for BananaPro.
Fix the phy-mode description to correctly reflect this so that the
implementation doesn't reconfigure the delays incorrectly. This
happened with commit bbc4d71d63 ("net: phy: realtek: fix rtl8211e
rx/tx delay config").

If not in long mode, the low bits of CR3 are reserved but not enforced to
be zero, so remove those checks. If in long mode, however, the MBZ bits
extend down to the highest physical address bit of the guest, excluding
the encryption bit.
Make the checks consistent with the above, and match them between
nested_vmcb_checks and KVM_SET_SREGS.

Don't let KVM load when running as an SEV guest, regardless of what
CPUID says. Memory is encrypted with a key that is not accessible to
the host (L0), thus it's impossible for L0 to emulate SVM, e.g. it'll
see garbage when reading the VMCB.
Technically, KVM could decrypt all memory that needs to be accessible to
the L0 and use shadow paging so that L0 does not need to shadow NPT, but
exposing such information to L0 largely defeats the purpose of running as
an SEV guest. This can always be revisited if someone comes up with a
use case for running VMs inside SEV guests.
Note, VMLOAD, VMRUN, etc... will also #GP on GPAs with C-bit set, i.e. KVM
is doomed even if the SEV guest is debuggable and the hypervisor is willing
to decrypt the VMCB. This may or may not be fixed on CPUs that have the
SVME_ADDR_CHK fix.

This reverts commit 6d4d273588.
bfq.limit_depth passes word_depths[] as shallow_depth down to sbitmap core
sbitmap_get_shallow, which uses just the number to limit the scan depth of
each bitmap word, formula:
scan_percentage_for_each_word = shallow_depth / (1 << sbimap->shift) * 100%
That means the comments's percentiles 50%, 75%, 18%, 37% of bfq are correct.
But after commit patch 'bfq: Fix computation of shallow depth', we use
sbitmap.depth instead, as a example in following case:
sbitmap.depth = 256, map_nr = 4, shift = 6; sbitmap_word.depth = 64.
The resulsts of computed bfqd->word_depths[] are {128, 192, 48, 96}, and
three of the numbers exceed core dirver's 'sbitmap_word.depth=64' limit
nothing.

Currently we discard the current context and recreate it. The current
context is what is applied to the HW so we should be re-using this
rather than creating a new context.
Recreating the context can lead to mismatch between new context and the
current context
For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.
[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.

Fix this by explicitly resetting the pointer tag prior to invoking

userspace (compat mode) to a 64-bit kernel, otherwise the RIP update at
the end of x86_emulate_insn() will incorrectly truncate the new RIP.
Note, this bug is mostly limited to running an Intel virtual CPU model on
an AMD physical CPU, as other combinations of virtual and physical CPUs
do not trigger full emulation. On Intel CPUs, SYSENTER in compatibility
mode is legal, and unconditionally transitions to 64-bit mode. On AMD
CPUs, SYSENTER is illegal in compatibility mode and #UDs. If the vCPU is
AMD, KVM injects a #UD on SYSENTER in compat mode. If the pCPU is Intel,
SYSENTER will execute natively and not trigger #UD->VM-Exit (ignoring
guest TLB shenanigans).

sup_multicast_addr is passed to ether_addr_equal for address comparison
which casts the address inputs to u16 leading to an unaligned access.
Aligning the sup_multicast_addr to u16 boundary fixes the issue.

====================
mlx5 fixes 2021-02-01
Please note the first patch in this series
("Fix function calculation for page trees") is fixing a regression
due to previous fix in net which you didn't include in your previous
rc pr. So I hope this series will make it into your next rc pr,
so mlx5 won't be broken in the next rc.
* tag 'mlx5-fixes-2021-02-01' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux:

====================
net: ipa: a few bug fixes
This series fixes four minor bugs. The first two are things that
sparse points out. All four are very simple and each patch should
explain itself pretty well.
