Pull copy_struct_from_user() helper from Christian Brauner:
"This contains the copy_struct_from_user() helper which got split out
from the openat2() patchset. It is a generic interface designed to
copy a struct from userspace.
The helper will be especially useful for structs versioned by size of
which we have quite a few. This allows for backwards compatibility,
i.e. an extended struct can be passed to an older kernel, or a legacy
struct can be passed to a newer kernel. For the first case (extended
struct, older kernel) the new fields in an extended struct can be set
to zero and the struct safely passed to an older kernel.
The most obvious benefit is that this helper lets us get rid of
duplicate code present in at least sched_setattr(), perf_event_open(),
and clone3(). More importantly it will also help to ensure that users
implementing versioning-by-size end up with the same core semantics.
This point is especially crucial since we have at least one case where
versioning-by-size is used but with slighly different semantics:
sched_setattr(), perf_event_open(), and clone3() all do do similar
checks to copy_struct_from_user() while rt_sigprocmask(2) always
rejects differently-sized struct arguments.
With this pull request we also switch over sched_setattr(),
perf_event_open(), and clone3() to use the new helper"

INTEL_PMC_MAX_GENERIC is currently 32, which exceeds the 18
contiguous MSR indices reserved by Intel for event selectors.
Since some machines actually have MSRs past the reserved range,
filtering them against x86_pmu.num_counters_gp may have false
positives. Cut the list to 18 entries to avoid this.

Today, put_compat_statfs64() disallows nearly any field value over
2^32 if f_bsize is only 32 bits, but that makes no sense.
compat_statfs64 is there for the explicit purpose of providing 64-bit
fields for f_files, f_ffree, etc. And f_bsize is always only 32 bits.
As a result, 32-bit userspace gets -EOVERFLOW for i.e. large file
counts even with -D_FILE_OFFSET_BITS=64 set.
In reality, only f_bsize and f_frsize can legitimately overflow
(fields like f_type and f_namelen should never be large), so test
only those fields.
This bug was discussed at length some time ago, and this is the proposal
Al suggested at https://lkml.org/lkml/2018/8/6/640. It seemed to get
dropped amid the discussion of other related changes, but this
part seems obviously correct on its own, so I've picked it up and
sent it, for expediency.

This reverts commit 4eaceea3a0.
Several userspace clients (modesetting ddx and mutter+wayland at least)
handle encoder.possible_crtcs incorrectly. What they essentially do is
the following:
possible_crtcs = ~0;
for_each_possible_encoder(connector)
possible_crtcs &= encoder->possible_crtcs;
Ie. they calculate the intersection of the possible_crtcs
for the connector when they really should be calculating the
union instead.
In our case each MST encoder now has just one unique bit set,
and so the intersection is always zero. The end result is that
MST connectors can't be lit up because no crtc can be found to
drive them.
I've submitted a fix for the modesetting ddx [1], and complained
on #wayland about mutter, so hopefully the situation will improve
in the future. In the meantime we have regression, and so must go
back to the old way of misconfiguring possible_crtcs in the kernel.

Here are fixes for omaps to deal with few regressions, and to fix

- The recent ti-sysc interconnect target module driver changes had
incorrect clock bits for both clocks and dts that cause warnings
- For omap3-gta04, gpio changes caused the LCD to break a while back,
and after discussing things the right fix is to set spi-cs-high
- Recent omapdrm changes to use generic panels caused tfp410 to be
disabled as we now must enable the generic support for it in
defconfig
- Recent omapdrm and backlight changes also finally made droid4 LCD
to work, so let's enable it in the defconfig it can be used out
of the box. This is not strictly a fix, but we still also have the
older CONFIG_MFD_TI_LMU options available so this cuts down the
confusion for trying to guess which display and which backlight
is needed
- Recent ti-sysc interconnect target module changes need the gpio
module disabled on some boards, but this now needs to happen at
the module level, not at the gpio driver level
- Recent changes to probe system timers with ti-sysc caused warnings
about mismatch in syconfig registers, so let's configure the option
for RESET_STATUS as available in the TRMs
- Recent changes to probe LCDC with ti-sysc caused warnings about
mismatch in sysconfig registers, so let's configure the missing
idlemodes for both platform data and dts as documented in TRMs
- Since we moved mach-omap2 to probe with device tree, we've been
getting voltage controller warnings. Turns out this code is no
longer needed, so let's just remove omap2_set_init_voltage() to
get rid of the pointless warnings
- Configure am4372 dispc memory bandwidth to avoid underflow errors

Prior to this change an application sending <= 1MSS worth of data and
enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.
With this change we only perform GSO if the # of segments is > 1 even
if the application has enabled segmentation. I've also updated the
relevant udpgso selftests.

This began with a syzbot report. syzkaller was injecting
IPv6 TCP SYN packets having a v4mapped source address.
After an unsuccessful 4-tuple lookup, TCP creates a request
socket (SYN_RECV) and calls reqsk_queue_hash_req()
reqsk_queue_hash_req() calls sk_ehashfn(sk)
At this point we have AF_INET6 sockets, and the heuristic
used by sk_ehashfn() to either hash the IPv4 or IPv6 addresses
is to use ipv6_addr_v4mapped(&sk->sk_v6_daddr)
For the particular spoofed packet, we end up hashing V4 addresses
which were not initialized by the TCP IPv6 stack, so KMSAN fired
a warning.
I first fixed sk_ehashfn() to test both source and destination addresses,
but then faced various problems, including user-space programs
like packetdrill that had similar assumptions.
Instead of trying to fix the whole ecosystem, it is better
to admit that we have a dual stack behavior, and that we
can not build linux kernels without V4 stack anyway.
The dual stack API automatically forces the traffic to be IPv4
if v4mapped addresses are used at bind() or connect(), so it makes
no sense to allow IPv6 traffic to use the same v4mapped class.

Current versions of Intel's SDM incorrectly state that "bits 31:15 of
the VM-Entry exception error-code field" must be zero. In reality, bits
31:16 must be zero, i.e. error codes are 16-bit values.
The bogus error code check manifests as an unexpected VM-Entry failure
due to an invalid code field (error number 7) in L1, e.g. when injecting
a #GP with error_code=0x9f00.
Nadav previously reported the bug[*], both to KVM and Intel, and fixed
the associated kvm-unit-test.

Merge tag 'kvmarm-fixes-5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm fixes for 5.4, take #1
- Remove the now obsolete hyp_alternate_select construct
- Fix the TRACE_INCLUDE_PATH macro in the vgic code
INTEL_PMC_MAX_GENERIC is currently 32, which exceeds the 18 contiguous
MSR indices reserved by Intel for event selectors. Since some machines
actually have MSRs past the reserved range, these may survive the
filtering of msrs_to_save array and would be rejected by KVM_GET/SET_MSR.
To avoid this, cut the list to whatever CPUID reports for the host's
architectural PMU.

Fix the following build error from "make TARGETS=kvm kselftest":
libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC
This error is seen when build is done from the main Makefile using
kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
are defined.
When build is invoked using:
"make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
aren't defined.
There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the
check to determine if --no-pie is necessary, which is the case when these
two aren't defined when "make -C tools/testing/selftests/kvm" runs.
Fix it by simplifying the no-pie-option logic. With this change, both
build variations work.
"make TARGETS=kvm kselftest"
"make -C tools/testing/selftests/kvm"

Merge drm-misc-next-fixes-2019-10-02 into drm-misc-fixes
One tilcdc fix was left out in drm-misc-next-fixes and didn't make it
during the merge window. Let's bring it into drm-misc-fixes.

The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk
(in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not
correct, and using divider of 32 breaks DSS with a flood or underflows
and sync losts. Dividers up to 31 seem to work fine.
There is another patch to the DT files to limit the divider correctly,
but as the DSS driver also needs to know the maximum divider to be able
to iteratively find good rates, we also need to do the fix in the DSS
driver.

I forgot to update the g4x sprite scaling stride check when GTT
remapping was introduced. The stride of the original framebuffer
is irrelevant when remapping is used and instead we want to check
the stride of the remapped view.
Also drop the duplicate width_bytes check. We already check that
a few lines earlier.
