fix this by using sizeof(*dev->urb_buffer). The sizeof(dma_addr_t *)

For sinks that do not support audio, there is no need to notify
audio subsystem of the connection event.
This will make sure that audio routes only to the primary display
when connected to such sinks.

Some dongle will not clear LINK_STATUS_UPDATED bit after

just read 6 bytes of DPCD link status from sink and return
without checking LINK_STATUS_UPDATED bit.
Only 8 bits are used to represent link rate at sinker DPCD.
The really link rate is 2.7Mb times the 8 bits value.
For example, 0x0A at DPCD is equal to 2.7Gb (10 * 2.7Mb).
This patch also convert 8 bits value of DPCD to really link

drm/msm/dp: return correct connection status after suspend

During suspend, dp host controller and hpd block are disabled due to
both ahb and aux clock are disabled. Therefore hpd plug/unplug interrupts
will not be generated. At dp_pm_resume(), reinitialize both dp host
controller and hpd block so that hpd plug/unplug interrupts will be

There are two issues in this function.
1) We can't drop the refrences on "cpu", "codec" and "platform" before
we take the reference. This doesn't cause a problem on the first
iteration because those pointers start as NULL so the of_node_put()
is a no-op. But on the subsequent iterations, it will lead to a use
after free.

directly instead of cleaning up.

arm64: dts: exynos: Correct psci compatible used on Exynos7
[ Upstream commit
e1e47fbca668507a81bb388fcae044b89d112ecc ]
It's not possible to reboot or poweroff Exynos7420 using PSCI. Instead
we need to use syscon reboot/poweroff drivers, like it's done for other
Exynos SoCs. This was confirmed by checking vendor source and testing it
on Samsung Galaxy S6 device based on this SoC.
To be able to use custom restart/poweroff handlers instead of PSCI
functions, we need to correct psci compatible. This also requires us to
provide function ids for CPU_ON and CPU_OFF.

Exynos7 uses the same syscon reboot and poweroff nodes as other Exynos

ath11k: Fix number of rules in filtered ETSI regdomain
[ Upstream commit
6189be7d145c3a2d48514eb8755483602ff5a4b4 ]
The ath11k code will try to insert wheather rader related limits when the
DFS region is set to ETSI. For this reason, it will add two more entries in
the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list
of reg rules it returns for 2.4GHz PHYs. They will then not contain the
list of 5GHz rules and thus no wheather radar band rules were inserted by
this code.
But the code didn't fix the n_reg_rules for this regulatory domain and PHY
when this happened. This resulted in a rejection by is_valid_rd because it
found rules which start and end at 0khz. This resulted in a splat like:
Invalid regulatory domain detected

A previous fix, commit
83370b31a915 ("selinux: fix error initialization
in inode_doinit_with_dentry()"), changed how failures were handled
before a SELinux policy was loaded. Unfortunately that patch was
potentially problematic for two reasons: it set the isec->initialized
state without holding a lock, and it didn't set the inode's SELinux
label to the "default" for the particular filesystem. The later can
be a problem if/when a later attempt to revalidate the inode fails
and SELinux reverts to the existing inode label.
This patch should restore the default inode labeling that existed
before the original fix, without affecting the LABEL_INVALID marking
such that revalidation will still be attempted in the future.

drm/msm/dpu: fix clock scaling on non-sc7180 board

c33b7c0389e1 ("drm/msm/dpu: add support for clk and bw scaling for
display") has added support for handling bandwidth voting in kms path in
addition to old mdss path. However this broke all other platforms since
_dpu_core_perf_crtc_update_bus() will now error out instead of properly
calculating bandwidth and core clocks. Fix
_dpu_core_perf_crtc_update_bus() to just skip bandwidth setting instead
of returning an error in case kms->num_paths == 0 (MDSS is used for
bandwidth management).

powerpc/64: Set up a kernel stack for secondaries before cpu_restore()
[ Upstream commit
3c0b976bf20d236c57adcefa80f86a0a1d737727 ]
Currently in generic_secondary_smp_init(), cur_cpu_spec->cpu_restore()
is called before a stack has been set up in r1. This was previously fine
as the cpu_restore() functions were implemented in assembly and did not
use a stack. However commit
5a61ef74f269 ("powerpc/64s: Support new
device tree binding for discovering CPU features") used
__restore_cpu_cpufeatures() as the cpu_restore() function for a
device-tree features based cputable entry. This is a C function and
hence uses a stack in r1.
generic_secondary_smp_init() is entered on the secondary cpus via the
primary cpu using the OPAL call opal_start_cpu(). In OPAL, each hardware
thread has its own stack. The OPAL call is ran in the primary's hardware
thread. During the call, a job is scheduled on a secondary cpu that will
start executing at the address of generic_secondary_smp_init(). Hence
the value that will be left in r1 when the secondary cpu enters the
kernel is part of that secondary cpu's individual OPAL stack. This means
that __restore_cpu_cpufeatures() will write to that OPAL stack. This is
not horribly bad as each hardware thread has its own stack and the call
that enters the kernel from OPAL never returns, but it is still wrong
and should be corrected.
Create the temp kernel stack before calling cpu_restore().
As noted by mpe, for a kexec boot, the secondary CPUs are released from
the spin loop at address 0x60 by smp_release_cpus() and then jump to
generic_secondary_smp_init(). The call to smp_release_cpus() is in
setup_arch(), and it comes before the call to emergency_stack_init().
emergency_stack_init() allocates an emergency stack in the PACA for each
CPU. This address in the PACA is what is used to set up the temp kernel
stack in generic_secondary_smp_init(). Move releasing the secondary CPUs
to after the PACAs have been allocated an emergency stack, otherwise the
PACA stack pointer will contain garbage and hence the temp kernel stack
created from it will be broken.

[ Upstream commit

When rtrs_rdma_conn_established returns error (non-zero value), the error
value is stored in con->cm_err and it cannot trigger
rtrs_rdma_error_recovery. Finally the error of rtrs_rdma_con_established
will be forgot.

Don't call destroy_con_cq_qp from rtrs_rdma_addr_resolved, create_cm()

ARM: p2v: fix handling of LPAE translation in BE mode
[ Upstream commit
4e79f0211b473f8e1eab8211a9fd50cc41a3a061 ]
When running in BE mode on LPAE hardware with a PA-to-VA translation
that exceeds 4 GB, we patch bits 39:32 of the offset into the wrong
byte of the opcode. So fix that, by rotating the offset in r0 to the
right by 8 bits, which will put the 8-bit immediate in bits 31:24.
Note that this will also move bit #22 in its correct place when
applying the rotation to the constant #0x400000.

x86/mm/ident_map: Check for errors from ident_pud_init()

Commit
ea3b5e60ce80 ("x86/mm/ident_map: Add 5-level paging support")
added ident_p4d_init() to support 5-level paging, but this function
doesn't check and return errors from ident_pud_init().
For example, the decompressor stub uses this code to create an identity
mapping. If it runs out of pages while trying to allocate a PMD
pagetable, the error will be currently ignored.
Fix this to propagate errors.

RDMA/rxe: Compute PSN windows correctly
[ Upstream commit
bb3ab2979fd69db23328691cb10067861df89037 ]
The code which limited the number of unacknowledged PSNs was incorrect.
The PSNs are limited to 24 bits and wrap back to zero from 0x00ffffff.
The test was computing a 32 bit value which wraps at 32 bits so that
qp->req.psn can appear smaller than the limit when it is actually larger.
Replace '>' test with psn_compare which is used for other PSN comparisons
and correctly handles the 24 bit size.

ARM: dts: aspeed: s2600wf: Fix VGA memory region location
[ Upstream commit
9e1cc9679776f5b9e42481d392b1550753ebd084 ]
The VGA memory region is always from the top of RAM. On this board, that
is 0x80000000 + 0x20000000 - 0x01000000 = 0x9f000000.
This was not an issue in practice as the region is "reserved" by the
vendor's u-boot reducing the amount of available RAM, and the only user
is the host VGA device poking at RAM over PCIe. That is, nothing from
the ARM touches it.
It is worth fixing as developers copy existing device trees when
building their machines, and the XDMA driver does use the memory region
from the ARM side.
