Pull x86 fixes from Thomas Gleixner:
"An unfortunately larger set of fixes, but a large portion is
selftests:
- Fix the missing clusterid initializaiton for x2apic cluster
management which caused boot failures due to IPIs being sent to the
wrong cluster
- Drop TX_COMPAT when a 64bit executable is exec()'ed from a compat
task
- Wrap access to __supported_pte_mask in __startup_64() where clang
compile fails due to a non PC relative access being generated.
- Two fixes for 5 level paging fallout in the decompressor:
- Handle GOT correctly for paging_prepare() and
cleanup_trampoline()
- Fix the page table handling in cleanup_trampoline() to avoid
page table corruption.
- Stop special casing protection key 0 as this is inconsistent with
the manpage and also inconsistent with the allocation map handling.
- Override the protection key wen moving away from PROT_EXEC to
prevent inaccessible memory.

Pull ARM SoC fixes from Olof Johansson:
"A handful of fixes. I've been queuing them up a bit too long so the
list is longer than it otherwise would have been spread out across a
few -rcs.
In general, it's a scattering of fixes across several platforms,
nothing truly serious enough to point out.
There's a slightly larger batch of them for the Davinci platforms due
to work to bring them back to life after some time, so there's a
handful of regressions, some of them going back very far, others more
recent.
There's also a few patches fixing DT on Renesas platforms since they
changed some bindings without remaining backwards compatible,
splitting up describing LVDS as a proper bridge instead of having it
as part of the display unit.
We could push for them to be backwards compatible with old device
trees, but it's likely to regress eventually if nobody's actually
using said compatibility"

arm64: tegra: Device tree fixes for v4.17
This contains a one-line update to the device tree of the Tegra186 P3310
processor module, fixing the polarity of the PHY interrupt. Originally,
this was queued to go into v4.18, but the PHY ID matching patch has now
found its way into v4.17-rc5, which means that the PHY driver will know
how to identify the PHY on this board and try to use the interrupt. This
will unfortunately cause networking to break on P3310, hence why I think
this should go into v4.17.

You can build a kernel in a cross compiling environment that doesn't
have perl in the $PATH. Commit 429f7a062e3b broke that for 32 bit
ARM. Fix it.
As reported by Stephen Rothwell, it appears that the symbols can be
either part of the BSS section or absolute symbols depending on the
binutils version. When they're an absolute symbol, the $(( ))
operator errors out and the build fails. Fix this as well.

How we got to machine_crash_nonpanic_core() (iow, from an IPI, etc) is
not interesting for debugging a crash. The more interesting context
is the parent context prior to the IPI being received.
Record the parent context register state rather than the register state
in machine_crash_nonpanic_core(), which is more relevant to the failing
condition.

When a panic() occurs, the kexec code uses smp_send_stop() to stop
the other CPUs, but this results in the CPU register state not being
saved, and gdb is unable to inspect the state of other CPUs.
Commit 0ee59413c967 ("x86/panic: replace smp_send_stop() with kdump
friendly version in panic path") addressed the issue on x86, but
ignored other architectures. Address the issue on ARM by splitting
out the crash stop implementation to crash_smp_send_stop() and
adding the necessary protection.

The x86 mmap() code selects the mmap base for an allocation depending on
the bitness of the syscall. For 64bit sycalls it select mm->mmap_base and
for 32bit mm->mmap_compat_base.
exec() calls mmap() which in turn uses in_compat_syscall() to check whether
the mapping is for a 32bit or a 64bit task. The decision is made on the
following criteria:
ia32 child->thread.status & TS_COMPAT
x32 child->pt_regs.orig_ax & __X32_SYSCALL_BIT
ia64 !ia32 && !x32
__set_personality_x32() was dropping TS_COMPAT flag, but
set_personality_64bit() has kept compat syscall flag making
in_compat_syscall() return true during the first exec() syscall.
Which in result has user-visible effects, mentioned by Alexey:
1) It breaks ASAN

Rick bisected a regression on large systems which use the x2apic cluster
mode for interrupt delivery to the commit wich reworked the cluster
management.
The problem is caused by a missing initialization of the clusterid field
in the shared cluster data structures. So all structures end up with
cluster ID 0 which only allows sharing between all CPUs which belong to
cluster 0. All other CPUs with a cluster ID > 0 cannot share the data
structure because they cannot find existing data with their cluster
ID. This causes malfunction with IPIs because IPIs are sent to the wrong
cluster and the caller waits for ever that the target CPU handles the IPI.
Add the missing initialization when a upcoming CPU is the first in a
cluster so that the later booting CPUs can find the data and share it for
proper operation.

KVM_HINTS_DEDICATED seems to be somewhat confusing:
Guest doesn't really care whether it's the only task running on a host

And there are more reasons for Guest to be preempted than host CPU
sharing, for example, with memory overcommit it can get preempted on a
memory access, post copy migration can cause preemption, etc.
Let's call it KVM_HINTS_REALTIME which seems to better
match what guests expect.
Also, the flag most be set on all vCPUs - current guests assume this.
Note so in the documentation.

Pull tracing fix from Steven Rostedt:
"Some of the ftrace internal events use a zero for a data size of a
field event. This is increasingly important for the histogram trigger
work that is being extended.
While auditing trace events, I found that a couple of the xen events
were used as just marking that a function was called, by creating a
static array of size zero. This can play havoc with the tracing
features if these events are used, because a zero size of a static
array is denoted as a special nul terminated dynamic array (this is
what the trace_marker code uses). But since the xen events have no
size, they are not nul terminated, and unexpected results may occur.
As trace events were never intended on being a marker to denote that a
function was hit or not, especially since function tracing and kprobes
can trivially do the same, the best course of action is to simply
remove these events"

cleanup_trampoline() relocates the top-level page table out of
trampoline memory. We use 'top_pgtable' as our new top-level page table.
But if the 'top_pgtable' would be referenced from C in a usual way,
the address of the table will be calculated relative to RIP.
After kernel gets relocated, the address will be in the middle of
decompression buffer and the page table may get overwritten.
This leads to a crash.
We calculate the address of other page tables relative to the relocation
address. It makes them safe. We should do the same for 'top_pgtable'.
Calculate the address of 'top_pgtable' in assembly and pass down to
cleanup_trampoline().
Move the page table to .pgtable section where the rest of page tables
are. The section is @nobits so we save 4k in kernel image.

Eric and Hugh have reported instant reboot due to my recent changes in
decompression code.
The root cause is that I didn't realize that we need to adjust GOT to be
able to run C code that early.
The problem is only visible with an older toolchain. Binutils >= 2.24 is
able to eliminate GOT references by replacing them with RIP-relative
address loads:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=80d873266dec
We need to adjust GOT two times:
- before calling paging_prepare() using the initial load address
- before calling C code from the relocated kernel

kvm_read_guest() will eventually look up in kvm_memslots(), which requires
either to hold the kvm->slots_lock or to be inside a kvm->srcu critical
section.
In contrast to x86 and s390 we don't take the SRCU lock on every guest
exit, so we have to do it individually for each kvm_read_guest() call.
Provide a wrapper which does that and use that everywhere.
Note that ending the SRCU critical section before returning from the
kvm_read_guest() wrapper is safe, because the data has been *copied*, so
we don't need to rely on valid references to the memslot anymore.

Anthoine reported:
The period used by Windows change over time but it can be 1
milliseconds or less. I saw the limit_periodic_timer_frequency
print so 500 microseconds is sometimes reached.
As suggested by Paolo, lower the default timer frequency limit to a
smaller interval of 200 us (5000 Hz) to leave some headroom. This
is required due to Windows 10 changing the scheduler tick limit
from 1024 Hz to 2048 Hz.

trace_xen_mmu_flush_tlb{_all}
Doing an audit of trace events, I discovered two trace events in the xen
subsystem that use a hack to create zero data size trace events. This is not
what trace events are for. Trace events add memory footprint overhead, and
if all you need to do is see if a function is hit or not, simply make that
function noinline and use function tracer filtering.
Worse yet, the hack used was:
__array(char, x, 0)
Which creates a static string of zero in length. There's assumptions about
such constructs in ftrace that this is a dynamic string that is nul
terminated. This is not the case with these tracepoints and can cause
problems in various parts of ftrace.
Nuke the trace events!

platform_domain_notifier contains a variable sized array, which the
pm_clk_notify() notifier treats as a NULL terminated array:
for (con_id = clknb->con_ids; *con_id; con_id++)
pm_clk_add(dev, *con_id);
Omitting the initialiser for con_ids means that the array is zero
sized, and there is no NULL terminator. This leads to pm_clk_notify()
overrunning into what ever structure follows, which may not be NULL.
This leads to an oops:

mm_pkey_is_allocated() treats pkey 0 as unallocated. That is
inconsistent with the manpages, and also inconsistent with
mm->context.pkey_allocation_map. Stop special casing it and only
disallow values that are actually bad (< 0).
The end-user visible effect of this is that you can now use
mprotect_pkey() to set pkey=0.
This is a bit nicer than what Ram proposed[1] because it is simpler
and removes special-casing for pkey 0. On the other hand, it does
allow applications to pkey_free() pkey-0, but that's just a silly
thing to do, so we are not going to protect against it.
The scenario that could happen is similar to what happens if you free
any other pkey that is in use: it might get reallocated later and used
to protect some other data. The most likely scenario is that pkey-0
comes back from pkey_alloc(), an access-disable or write-disable bit
is set in PKRU for it, and the next stack access will SIGSEGV. It's
not horribly different from if you mprotect()'d your stack or heap to
be unreadable or unwritable, which is generally very foolish, but also
not explicitly prevented by the kernel.

I got a bug report that the following code (roughly) was
causing a SIGSEGV:
mprotect(ptr, size, PROT_EXEC);
mprotect(ptr, size, PROT_NONE);
mprotect(ptr, size, PROT_READ);
*ptr = 100;
The problem is hit when the mprotect(PROT_EXEC)
is implicitly assigned a protection key to the VMA, and made
that key ACCESS_DENY|WRITE_DENY. The PROT_NONE mprotect()
failed to remove the protection key, and the PROT_NONE->
PROT_READ left the PTE usable, but the pkey still in place
and left the memory inaccessible.
To fix this, we ensure that we always "override" the pkee
at mprotect() if the VMA does not have execute-only
permissions, but the VMA has the execute-only pkey.
We had a check for PROT_READ/WRITE, but it did not work
for PROT_NONE. This entirely removes the PROT_* checks,
which ensures that PROT_NONE now works.

Clang builds with defconfig started crashing after the following
commit:
fb43d6cb91ef ("x86/mm: Do not auto-massage page protections")
This was caused by introducing a new global access in __startup_64().
Code in __startup_64() can be relocated during execution, but the compiler
doesn't have to generate PC-relative relocations when accessing globals
from that function. Clang actually does not generate them, which leads
to boot-time crashes. To work around this problem, every global pointer
must be adjusted using fixup_pointer().

ARM: tegra: Device tree fixes for v4.17

original issue that the patch was supposed to fix seems to have
disappeared.
