ff17bbe0bb x86/vdso: Prevent segfaults due to hoisted vclock reads
GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock
pages before the vclock mode checks.  This creates a path through
vclock_gettime() in which no vclock is enabled at all (due to disabled
TSC on old CPUs, for example) but the pvclock or hvclock page
nevertheless read.  This will segfault on bare metal.

This fixes commit 459e3a2153 ("gcc-9: properly declare the
{pv,hv}clock_page storage") in the sense that, before that commit, GCC
didn't seem to generate the offending code.  There was nothing wrong
with that commit per se, and -stable maintainers should backport this to
all supported kernels regardless of whether the offending commit was
present, since the same crash could just as easily be triggered by the
phase of the moon.

On GCC 9.1.1, this doesn't seem to affect the generated code at all, so
I'm not too concerned about performance regressions from this fix.

19d55046cd SUNRPC: Fix a credential refcount leak
All callers of __rpc_clone_client() pass in a value for args->cred,
meaning that the credential gets assigned and referenced in
the call to rpc_new_client().

502980e84e Revert "SUNRPC: Declare RPC timers as TIMER_DEFERRABLE"
Jon Hunter reports:
  "I have been noticing intermittent failures with a system suspend test on
   some of our machines that have a NFS mounted root file-system. Bisecting
   this issue points to your commit 431235818b ("SUNRPC: Declare RPC
   timers as TIMER_DEFERRABLE") and reverting this on top of v5.2-rc3 does
   appear to resolve the problem.

   The cause of the suspend failure appears to be a long delay observed
   sometimes when resuming from suspend, and this is causing our test to
   timeout."

This reverts commit 431235818b.

909105199a NFS4: Only set creation opendata if O_CREAT
We can end up in nfs4_opendata_alloc during task exit, in which case
current->fs has already been cleaned up.  This leads to a crash in
current_umask().

Fix this by only setting creation opendata if we are actually doing an open
with O_CREAT.  We can drop the check for NULL nfs4_open_createattrs, since
O_CREAT will never be set for the recovery path.

c884d8ac7f SPDX update for 5.2-rc6
Another round of SPDX updates for 5.2-rc6
 
 Here is what I am guessing is going to be the last "big" SPDX update for
 5.2.  It contains all of the remaining GPLv2 and GPLv2+ updates that
 were "easy" to determine by pattern matching.  The ones after this are
 going to be a bit more difficult and the people on the spdx list will be
 discussing them on a case-by-case basis now.
 
 Another 5000+ files are fixed up, so our overall totals are:
 	Files checked:            64545
 	Files with SPDX:          45529
 
 Compared to the 5.1 kernel which was:
 	Files checked:            63848
 	Files with SPDX:          22576
 This is a huge improvement.
 
 Also, we deleted another 20000 lines of boilerplate license crud, always
 nice to see in a diffstat.

47e3c4c964 Merge branch 'vmwgfx-fixes-5.2' of git://people.freedesktop.org/~thomash/linux into drm-fixes
A couple of fixes for vmwgfx. Two fixes for a DMA sg-list debug warning
message. These are not cc'd stable since there is no evidence of actual
breakage.
On fix for the high-bandwidth backdoor port which is cc'd stable due to
upcoming hardware, on which the code would otherwise break.

c5d0e49e8d ARM: 8867/1: vdso: pass --be8 to linker if necessary
The commit fe00e50b2d ("ARM: 8858/1: vdso: use $(LD) instead of $(CC)
to link VDSO") removed the passing of CFLAGS, since ld doesn't take
those directly. However, prior, big-endian ARM was relying on gcc to
translate its -mbe8 option into ld's --be8 option. Lacking this, ld
generated be32 code, making the VDSO generate SIGILL when called by
userspace.

This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled.

9fd5887726 KVM: nVMX: reorganize initial steps of vmx_set_nested_state
Commit 332d079735 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS
state before setting new state", 2019-05-02) broke evmcs_test because the
eVMCS setup must be performed even if there is no VMXON region defined,
as long as the eVMCS bit is set in the assist page.

While the simplest possible fix would be to add a check on
kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that
covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.

Instead, this patch moves checks earlier in the function and
conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that
vmx_set_nested_state always goes through vmx_leave_nested
and nested_enable_evmcs.

Fixes: 332d079735 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state")

5008711259 KVM: PPC: Book3S HV: Invalidate ERAT when flushing guest TLB entries
When a guest vcpu moves from one physical thread to another it is
necessary for the host to perform a tlb flush on the previous core if
another vcpu from the same guest is going to run there. This is because the
guest may use the local form of the tlb invalidation instruction meaning
stale tlb entries would persist where it previously ran. This is handled
on guest entry in kvmppc_check_need_tlb_flush() which calls
flush_guest_tlb() to perform the tlb flush.

Previously the generic radix__local_flush_tlb_lpid_guest() function was
used, however the functionality was reimplemented in flush_guest_tlb()
to avoid the trace_tlbie() call as the flushing may be done in real
mode. The reimplementation in flush_guest_tlb() was missing an erat
invalidation after flushing the tlb.

This lead to observable memory corruption in the guest due to the
caching of stale translations. Fix this by adding the erat invalidation.

ASoC: rt5514-spi: don't use snd_soc_lookup_component()
rt5514-spi can use dev_get_drvdata() to get its component
because it is using snd_soc_component_set_drvdata();

	static int rt5514_spi_pcm_probe(...)
	{
		...
=>		snd_soc_component_set_drvdata(component, ...);
		...
	}

We don't need to use snd_soc_lookup_component() for it.
This patch uses dev_get_drvdata() instead of snd_soc_lookup_component().

ASoC: pcm3168a: Add support for multi DIN/DOUT with TDM slots parameter
The driver was wired to be only usable in DIN1/DOUT1 mode, switching
between TDM and non TDM modes based on the number of channels.

While keeping this functionality for compatibility add support for using
all DIN1/2/3/4 and DOUT1/2/3 if it is needed by setting the TDM slots to
2.

support code shared by all Madera codecs.

This patch also adds the pdata to the parent mfd pdata struct.
Since there is a circular build dependency it's convenient to
patch them both atomically.

85f9aa7565 inet: clear num_timeout reqsk_alloc()
KMSAN caught uninit-value in tcp_create_openreq_child() [1]
This is caused by a recent change, combined by the fact
that TCP cleared num_timeout, num_retrans and sk fields only
when a request socket was about to be queued.

Under syncookie mode, a temporary request socket is used,
and req->num_timeout could contain garbage.

Lets clear these three fields sooner, there is really no
point trying to defer this and risk other bugs.

6dbbd053e6 PCI/P2PDMA: Ignore root complex whitelist when an IOMMU is present
Presently, there is no path to DMA map P2PDMA memory, so if a TLP targeting
this memory hits the root complex and an IOMMU is present, the IOMMU will
reject the transaction, even if the RC would support P2PDMA.

So until the kernel knows to map these DMA addresses in the IOMMU, we
should not enable the whitelist when an IOMMU is present.

There was an unused variable 'mvpp2_dbgfs_prs_pmap_fops'
Added a usage consistent with other fops to dump pmap

c7036d97ac ipv6: Default fib6_type to RTN_UNICAST when not set
A user reported that routes are getting installed with type 0 (RTN_UNSPEC)
where before the routes were RTN_UNICAST. One example is from accel-ppp
which apparently still uses the ioctl interface and does not set
rtmsg_type. Another is the netlink interface where ipv6 does not require
rtm_type to be set (v4 does). Prior to the commit in the Fixes tag the
ipv6 stack converted type 0 to RTN_UNICAST, so restore that behavior.

99838e602b Merge branch 'af_iucv-fixes'
Julian Wiedmann says:

====================
net/af_iucv: fixes 2019-06-18

I spent a few cycles on transmit problems for af_iucv over regular
netdevices - please apply the following fixes to -net.

The first patch allows for skb allocations outside of GFP_DMA, while the
second patch respects that drivers might use skb_cow_head() and/or want
additional dev->needed_headroom.
Patch 3 is for a separate issue, where we didn't setup some of the
netdevice-specific infrastructure when running as a z/VM guest.
