vm86_32.c:109 is: "BUG_ON(!vm86 || !vm86->user_vm86)"

When trying to understand the failure Brian Gerst pointed out[2] that
the code does not need protection against vm86->user_vm86 being NULL.
The copy_from_user code will already handles that case if the address
is going to fault.

Looking futher I realized that if we care about not allowing struct
vm86plus_struct at address 0 it should be do_sys_vm86 (the system
call) that does the filtering.  Not way down deep when the emulation
has completed in save_v86_state.

So let's just remove the silly case of attempting to filter a
userspace address with a BUG_ON.  Existing userspace can't break and
it won't make the kernel any more attackable as the userspace access
helpers will handle it, if it isn't a good userspace pointer.

I have run the reproducer the fuzzer gave me before I made this change
and it reproduced, and after I made this change and I have not seen
the reported failure.  So it does looks like this fixes the reported
issue.

KVM/arm64 fixes for 5.16, take #1

- Fix the host S2 finalization by solely iterating over the memblocks
  instead of the whole IPA space

- Tighten the return value of kvm_vcpu_preferred_target() now that
  32bit support is long gone

- Make sure the extraction of ESR_ELx.EC is limited to the architected

- Comment fixups

If a binary operation is detected while parsing an expression string,
the operand strings are deduced by splitting the experssion string at
the position of the detected binary operator. Both operand strings are
sub-strings (can be empty string) of the expression string but will
never be NULL.

Currently a NULL check is used for missing operands, fix this by
checking for empty strings instead.

Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

Do not copy the fixed-size char array field of the events over
the field size. The histogram treats char array as a string and
there are 2 types of char array in the event, fixed-size and
dynamic string. The dynamic string (__data_loc) field must be
null terminated, but the fixed-size char array field may not
be null terminated (not a string, but just a data).
In that case, histogram can copy the data after the field.
This uses the original field size for fixed-size char array
field to restrict the histogram not to access over the original
field size.

Pull RTC updates from Alexandre Belloni:

     backup switch mode
   - Expose available features to userspace, in particular, when alarmas
     have a resolution of one minute instead of a second.

TL;DR: While a tool like liblockdep is useful, it probably doesn't
belong within the kernel tree.

liblockdep attempts to reuse kernel code both directly (by directly
building the kernel's lockdep code) as well as indirectly (by using
sanitized headers). This makes liblockdep an integral part of the
kernel.

It also makes liblockdep quite unique: while other userspace code might
use sanitized headers, it generally doesn't attempt to use kernel code
directly which means that changes on the kernel side of things don't
affect (and break) it directly.

All our workflows and tooling around liblockdep don't support this
uniqueness. Changes that go into the kernel code aren't validated to not
break in-tree userspace code.

liblockdep ended up being very fragile, breaking over and over, to the
point that living in the same tree as the lockdep code lost most of it's
value.

liblockdep should continue living in an external tree, syncing with
the kernel often, in a controllable way.

Commit aeb58c86 ("thermal/drivers/int340x: processor_thermal: Suppot
64 bit RFIM responses") started using 'readq()' to read 64-bit status
responses from the int340x hardware.

That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is
ambiguous, since it's no longer an atomic access.  Some hardware might
require 64-bit accesses, and other hardware might want low word first or
high word first.

It's quite likely that the driver isn't relevant in a 32-bit environment
any more, and there's a patch floating around to just make it depend on
X86_64, but let's make it buildable on x86-32 anyway.

The driver previously just read the low 32 bits, so the hardware
certainly is ok with 32-bit reads, and in a little-endian environment
the low word first model is the natural one.

So just add the include for the 'io-64-nonatomic-lo-hi.h' version.

Pull PCI fixes from Bjorn Helgaas:
 "Revert conversion to struct device.driver instead of struct

  The device.driver is set earlier, and using it caused the PCI core to

ACS-3 introduced the ATA Identify Device Data log as mandatory. A
warning message currently signals to the user if a device does not
report supporting this log page in the log directory page, regardless
of the ATA version of the device. Furthermore, this warning will appear
for all attempts at accessing this missing log page during device
revalidation.

Since it is useless to constantly access the log directory and warn
about this lack of support once we have discovered that the device
does not support this log page, introduce the horkage flag
ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for
the Identify Device Data log page. Set this flag when
ata_log_supported() returns false in ata_identify_page_supported().
The warning is printed only if the device ATA level is 10 or above
(ACS-3 or above), and only once on device scan. With this flag set, the
log directory page is not accessed again to test for Identify Device
Data log page support.

This reverts commit 2a4d9408.

Robert reported a NULL pointer dereference caused by the PCI core
(local_pci_probe()) calling the i2c_designware_pci driver's
.runtime_resume() method before the .probe() method.  i2c_dw_pci_resume()
depends on initialization done by i2c_dw_pci_probe().

Prior to 2a4d9408 ("PCI: Use to_pci_driver() instead of
pci_dev->driver"), pci_pm_runtime_resume() avoided calling the
.runtime_resume() method because pci_dev->driver had not been set yet.

2a4d9408 and b5f9c644 ("PCI: Remove struct pci_dev->driver"),
removed pci_dev->driver, replacing it by device->driver, which *has* been
set by this time, so pci_pm_runtime_resume() called the .runtime_resume()
method when it previously had not.
