+Subject: drm/amd/display: Correct MPC split policy for DCN301
+
+From: Zhan Liu <zhan.liu@amd.com>
+
+[ Upstream commit ac46d93235074a6c5d280d35771c23fd8620e7d9 ]
+
+[Why]
+DCN301 has seamless boot enabled. With MPC split enabled
+at the same time, system will hang.
+
+[How]
+Revert MPC split policy back to "MPC_SPLIT_AVOID". Since we have
+ODM combine enabled on DCN301, pipe split is not necessary here.

+From: Sander Vanheule <sander@svanheule.net>
+
+[ Upstream commit 960dd884ddf5621ae6284cd3a42724500a97ae4c ]
+
+Instead of only servicing the lowest pending interrupt line, make sure
+all pending SoC interrupts are serviced before exiting the chained
+handler. This adds a small overhead if only one interrupt is pending,
+but should prevent rapid re-triggering of the handler.

+Subject: KVM: SVM: Don't kill SEV guest if SMAP erratum triggers in usermode
+
+From: Sean Christopherson <seanjc@google.com>
+
+[ Upstream commit cdf85e0c5dc766fc7fc779466280e454a6d04f87 ]
+
+Inject a #GP instead of synthesizing triple fault to try to avoid killing
+the guest if emulation of an SEV guest fails due to encountering the SMAP
+erratum. The injected #GP may still be fatal to the guest, e.g. if the
+userspace process is providing critical functionality, but KVM should
+make every attempt to keep the guest alive.

+Subject: KVM: VMX: Set vmcs.PENDING_DBG.BS on #DB in STI/MOVSS blocking shadow
+
+From: Sean Christopherson <seanjc@google.com>
+
+[ Upstream commit b9bed78e2fa9571b7c983b20666efa0009030c71 ]
+
+Set vmcs.GUEST_PENDING_DBG_EXCEPTIONS.BS, a.k.a. the pending single-step
+breakpoint flag, when re-injecting a #DB with RFLAGS.TF=1, and STI or
+MOVSS blocking is active. Setting the flag is necessary to make VM-Entry
+consistency checks happy, as VMX has an invariant that if RFLAGS.TF is
+set and STI/MOVSS blocking is true, then the previous instruction must
+have been STI or MOV/POP, and therefore a single-step #DB must be pending
+since the RFLAGS.TF cannot have been set by the previous instruction,
+i.e. the one instruction delay after setting RFLAGS.TF must have already
+expired.
+
+Normally, the CPU sets vmcs.GUEST_PENDING_DBG_EXCEPTIONS.BS appropriately
+when recording guest state as part of a VM-Exit, but #DB VM-Exits
+intentionally do not treat the #DB as "guest state" as interception of
+the #DB effectively makes the #DB host-owned, thus KVM needs to manually
+set PENDING_DBG.BS when forwarding/re-injecting the #DB to the guest.
+
+Note, although this bug can be triggered by guest userspace, doing so
+requires IOPL=3, and guest userspace running with IOPL=3 has full access
+to all I/O ports (from the guest's perspective) and can crash/reboot the
+guest any number of ways. IOPL=3 is required because STI blocking kicks
+in if and only if RFLAGS.IF is toggled 0=>1, and if CPL>IOPL, STI either
+takes a #GP or modifies RFLAGS.VIF, not RFLAGS.IF.
+
+MOVSS blocking can be initiated by userspace, but can be coincident with
+a #DB if and only if DR7.GD=1 (General Detect enabled) and a MOV DR is
+executed in the MOVSS shadow. MOV DR #GPs at CPL>0, thus MOVSS blocking
+is problematic only for CPL0 (and only if the guest is crazy enough to
+access a DR in a MOVSS shadow). All other sources of #DBs are either
+suppressed by MOVSS blocking (single-step, code fetch, data, and I/O),
+are mutually exclusive with MOVSS blocking (T-bit task switch), or are
+already handled by KVM (ICEBP, a.k.a. INT1).
+
+This bug was originally found by running tests[1] created for XSA-308[2].
+Note that Xen's userspace test emits ICEBP in the MOVSS shadow, which is
+presumably why the Xen bug was deemed to be an exploitable DOS from guest
+userspace. KVM already handles ICEBP by skipping the ICEBP instruction
+and thus clears MOVSS blocking as a side effect of its "emulation".

+Subject: KVM: x86: Report deprecated x87 features in supported CPUID
+
+From: Jim Mattson <jmattson@google.com>
+
+[ Upstream commit e3bcfda012edd3564e12551b212afbd2521a1f68 ]
+
+CPUID.(EAX=7,ECX=0):EBX.FDP_EXCPTN_ONLY[bit 6] and
+CPUID.(EAX=7,ECX=0):EBX.ZERO_FCS_FDS[bit 13] are "defeature"
+bits. Unlike most of the other CPUID feature bits, these bits are
+clear if the features are present and set if the features are not
+present. These bits should be reported in KVM_GET_SUPPORTED_CPUID,
+because if these bits are set on hardware, they cannot be cleared in
+the guest CPUID. Doing so would claim guest support for a feature that
+the hardware doesn't support and that can't be efficiently emulated.
+
+Of course, any software (e.g WIN87EM.DLL) expecting these features to
+be present likely predates these CPUID feature bits and therefore
+doesn't know to check for them anyway.
+
+Aaron Lewis added the corresponding X86_FEATURE macros in
+commit cbb99c0f5887 ("x86/cpufeatures: Add FDP_EXCPTN_ONLY and
+ZERO_FCS_FDS"), with the intention of reporting these bits in
+KVM_GET_SUPPORTED_CPUID, but I was unable to find a proposed patch on
+the kvm list.
+
+Opportunistically reordered the CPUID_7_0_EBX capability bits from
+least to most significant.

+
+From: Victor Nogueira <victor@mojatatu.com>
+
+[ Upstream commit 973bf8fdd12f0e70ea351c018e68edd377a836d1 ]
+
+When adding a tc rule with a qdisc kind that is not supported or not
+compiled into the kernel, the kernel emits the following error: "Error:
+Specified qdisc not found.". Found via tdc testing when ETS qdisc was not
+compiled in and it was not obvious right away what the message meant
+without looking at the kernel code.
+
+Change the error message to be more explicit and say the qdisc kind is
+unknown.

+Currently, on EEE capable platforms, if EEE SW timer is used, the SW

+Subject: net/sunrpc: fix reference count leaks in rpc_sysfs_xprt_state_change
+
+From: Xiyu Yang <xiyuyang19@fudan.edu.cn>
+
+[ Upstream commit 776d794f28c95051bc70405a7b1fa40115658a18 ]
+
+The refcount leak issues take place in an error handling path. When the
+3rd argument buf doesn't match with "offline", "online" or "remove", the
+function simply returns -EINVAL and forgets to decrease the reference
+count of a rpc_xprt object and a rpc_xprt_switch object increased by
+rpc_sysfs_xprt_kobj_get_xprt() and
+rpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of
+both unused objects.
+
+Fix this issue by jumping to the error handling path labelled with
+out_put when buf matches none of "offline", "online" or "remove".

+Subject: NFS: change nfs_access_get_cached to only report the mask
+
+From: NeilBrown <neilb@suse.de>
+
+[ Upstream commit b5e7b59c3480f355910f9d2c6ece5857922a5e54 ]
+
+Currently the nfs_access_get_cached family of functions report a
+'struct nfs_access_entry' as the result, with both .mask and .cred set.
+However the .cred is never used. This is probably good and there is no
+guarantee that it won't be freed before use.
+
+Change to only report the 'mask' - as this is all that is used or needed.

+
+An fs_location attribute returns a string that can be ipv4, ipv6,
+or DNS name. An ip location can have a port appended to it and if
+no port is present a default port needs to be set. If rpc_pton()
+fails to parse, try calling rpc_uaddr2socaddr() that can convert
+an universal address.

+[ Upstream commit b05bf5c63b326ce1da84ef42498d8e0e292e694c ]
+
+When decode_devicenotify_args() exits with no entries, we need to
+ensure that the struct cb_devicenotifyargs is initialised to
+{ 0, NULL } in order to avoid problems in
+nfs4_callback_devicenotify().

+Subject: perf: Always wake the parent event
+
+From: James Clark <james.clark@arm.com>
+
+[ Upstream commit 961c39121759ad09a89598ec4ccdd34ae0468a19 ]
+
+When using per-process mode and event inheritance is set to true,
+forked processes will create a new perf events via inherit_event() ->
+perf_event_alloc(). But these events will not have ring buffers
+assigned to them. Any call to wakeup will be dropped if it's called on
+an event with no ring buffer assigned because that's the object that
+holds the wakeup list.
+
+If the child event is disabled due to a call to
+perf_aux_output_begin() or perf_aux_output_end(), the wakeup is
+dropped leaving userspace hanging forever on the poll.
+
+Normally the event is explicitly re-enabled by userspace after it
+wakes up to read the aux data, but in this case it does not get woken
+up so the event remains disabled.
+
+This can be reproduced when using Arm SPE and 'stress' which forks once
+before running the workload. By looking at the list of aux buffers read,
+it's apparent that they stop after the fork:
+
+ perf record -e arm_spe// -vvv -- stress -c 1
+
+With this patch applied they continue to be printed. This behaviour
+doesn't happen when using systemwide or per-cpu mode.

+Subject: perf/x86/rapl: fix AMD event handling
+
+From: Stephane Eranian <eranian@google.com>
+
+[ Upstream commit 0036fb00a756a2f6e360d44e2e3d2200a8afbc9b ]
+
+The RAPL events exposed under /sys/devices/power/events should only reflect
+what the underlying hardware actually support. This is how it works on Intel
+RAPL and Intel core/uncore PMUs in general.
+But on AMD, this was not the case. All possible RAPL events were advertised.
+
+This is what it showed on an AMD Fam17h:
+$ ls /sys/devices/power/events/
+energy-cores energy-gpu energy-pkg energy-psys
+energy-ram energy-cores.scale energy-gpu.scale energy-pkg.scale
+energy-psys.scale energy-ram.scale energy-cores.unit energy-gpu.unit
+energy-pkg.unit energy-psys.unit energy-ram.unit
+
+Yet, on AMD Fam17h, only energy-pkg is supported.
+
+This patch fixes the problem. Given the way perf_msr_probe() works, the
+amd_rapl_msrs[] table has to have all entries filled out and in particular
+the group field, otherwise perf_msr_probe() defaults to making the event
+visible.
+
+With the patch applied, the kernel now only shows was is actually supported:
+
+$ ls /sys/devices/power/events/
+energy-pkg energy-pkg.scale energy-pkg.unit
+
+The patch also uses the RAPL_MSR_MASK because only the 32-bits LSB of the
+RAPL counters are relevant when reading power consumption.

+Subject: PM: hibernate: Remove register_nosave_region_late()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>
+
+[ Upstream commit 33569ef3c754a82010f266b7b938a66a3ccf90a4 ]
+
+It is an unused wrapper forcing kmalloc allocation for registering
+nosave regions. Also, rename __register_nosave_region() to
+register_nosave_region() now that there is no need for disambiguation.

+Subject: powerpc/fixmap: Fix VM debug warning on unmap
+
+From: Christophe Leroy <christophe.leroy@csgroup.eu>
+
+[ Upstream commit aec982603aa8cc0a21143681feb5f60ecc69d718 ]
+
+Unmapping a fixmap entry is done by calling __set_fixmap()
+with FIXMAP_PAGE_CLEAR as flags.
+
+Today, powerpc __set_fixmap() calls map_kernel_page().
+
+map_kernel_page() is not happy when called a second time
+for the same page.

+
+[ Upstream commit 7e406d1ff39b8ee574036418a5043c86723170cf ]
+
+For PREEMPT/DYNAMIC_PREEMPT the *_unlock() will already trigger a
+preemption, no point in then calling preempt_schedule_common()
+*again*.
+
+Use _cond_resched() instead, since this is a NOP for the preemptible

+Subject: scsi: pm8001: Fix bogus FW crash for maxcpus=1
+
+From: John Garry <john.garry@huawei.com>
+
+[ Upstream commit 62afb379a0fee7e9c2f9f68e1abeb85ceddf51b9 ]
+
+According to the comment in check_fw_ready() we should not check the
+IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.
+
+However we check this very field in process_oq() for processing the highest
+index interrupt vector. The highest interrupt vector is checked as the FW
+is programmed to signal fatal errors through this irq.
+
+Change that function to not check IOP1_READY for those mentioned
+controllers, but do check ILA_READY in both cases.
+
+The reason I assume that this was not hit earlier was because we always
+allocated 64 MSI(X), and just did not pass the vector index check in
+process_oq(), i.e. the handler never ran for vector index 63.

+
+[ Upstream commit 64fd4af6274eb0f49d29772c228fffcf6bde1635 ]
+
+If FCoE is not configured, libfc/libfcoe keeps on retrying FLOGI and after
+3 retries driver does a context reset and tries fipvlan again. This leads
+to context reset message flooding the logs. Hence ratelimit the message to

+
+This event is raised when link is lost as specified in UFSHCI spec and that
+means communication is not possible. Thus initializing UFS interface needs
+to be done.
+
+Make UFS driver considers Link Lost as fatal in the INT_FATAL_ERRORS

+From: Kiwoong Kim <kwmad.kim@samsung.com>

+
+The return value of ufshcd_set_dev_pwr_mode() is passed to device PM
+core. However, the function currently returns a SCSI result which the PM
+core doesn't understand. This might lead to unexpected behaviors in
+userland; a platform reset was observed in Android.
+
+Use a generic error code for SSU failures.

+
+From: Andi Kleen <ak@linux.intel.com>
+
+[ Upstream commit 8c16dc047b5dd8f7b3bf4584fa75733ea0dde7dc ]
+
+Some hypervisors support Arch LBR, but without the LBR XSAVE support.
+The current Arch LBR init code prints a warning when the xsave size (0) is
+unexpected. Avoid printing the warning for the "no LBR XSAVE" case.
