18306111e6 acpi: Extend TPM2 ACPI table with missing log fields
Recent extensions of the TPM2 ACPI table added 3 more fields
including 12 bytes of start method specific parameters and Log Area
Minimum Length (u32) and Log Area Start Address (u64). So, we define
a new structure acpi_tpm2_phy that holds these optional new fields.
The new fields allow non-UEFI systems to access the TPM2's log.

The specification that has the new fields is the following:
  TCG ACPI Specification
  Family "1.2" and "2.0"
  Version 1.2, Revision 8

6c4e79d99e tpm: Unify the mismatching TPM space buffer sizes
The size of the buffers for storing context's and sessions can vary from
arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the
maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be
enough for most use with three handles (that is how many we allow at the
moment). Parametrize the buffer size while doing this, so that it is easier
to revisit this later on if required.

7f3d176f5f tpm: Require that all digests are present in TCG_PCR_EVENT2 structures
Require that the TCG_PCR_EVENT2.digests.count value strictly matches the
value of TCG_EfiSpecIdEvent.numberOfAlgorithms in the event field of the
TCG_PCClientPCREvent event log header. Also require that
TCG_EfiSpecIdEvent.numberOfAlgorithms is non-zero.

The TCG PC Client Platform Firmware Profile Specification section 9.1
(Family "2.0", Level 00 Revision 1.04) states:

 For each Hash algorithm enumerated in the TCG_PCClientPCREvent entry,
 there SHALL be a corresponding digest in all TCG_PCR_EVENT2 structures.
 Note: This includes EV_NO_ACTION events which do not extend the PCR.

Section 9.4.5.1 provides this description of
TCG_EfiSpecIdEvent.numberOfAlgorithms:

 The number of Hash algorithms in the digestSizes field. This field MUST
 be set to a value of 0x01 or greater.

Enforce these restrictions, as required by the above specification, in
order to better identify and ignore invalid sequences of bytes at the
end of an otherwise valid TPM2 event log. Firmware doesn't always have
the means necessary to inform the kernel of the actual event log size so
the kernel's event log parsing code should be stringent when parsing the
event log for resiliency against firmware bugs. This is true, for
example, when firmware passes the event log to the kernel via a reserved
memory region described in device tree.

POWER and some ARM systems use the "linux,sml-base" and "linux,sml-size"
device tree properties to describe the memory region used to pass the
event log from firmware to the kernel. Unfortunately, the
"linux,sml-size" property describes the size of the entire reserved
memory region rather than the size of the event long within the memory
region and the event log format does not include information describing
the size of the event log.

tpm_read_log_of(), in drivers/char/tpm/eventlog/of.c, is where the
"linux,sml-size" property is used. At the end of that function,
log->bios_event_log_end is pointing at the end of the reserved memory
region. That's typically 0x10000 bytes offset from "linux,sml-base",
depending on what's defined in the device tree source.

The firmware event log only fills a portion of those 0x10000 bytes and
the rest of the memory region should be zeroed out by firmware. Even in
the case of a properly zeroed bytes in the remainder of the memory
region, the only thing allowing the kernel's event log parser to detect
the end of the event log is the following conditional in
__calc_tpm2_event_size():

        if (event_type == 0 && event_field->event_size == 0)
                size = 0;

If that wasn't there, __calc_tpm2_event_size() would think that a 16
byte sequence of zeroes, following an otherwise valid event log, was
a valid event.

However, problems can occur if a single bit is set in the offset
corresponding to either the TCG_PCR_EVENT2.eventType or
TCG_PCR_EVENT2.eventSize fields, after the last valid event log entry.
This could confuse the parser into thinking that an additional entry is
present in the event log and exposing this invalid entry to userspace in
the /sys/kernel/security/tpm0/binary_bios_measurements file. Such
problems have been seen if firmware does not fully zero the memory
region upon a warm reboot.

This patch significantly raises the bar on how difficult it is for
stale/invalid memory to confuse the kernel's event log parser but
there's still, ultimately, a reliance on firmware to properly initialize
the remainder of the memory region reserved for the event log as the
parser cannot be expected to detect a stale but otherwise properly
formatted firmware event log entry.

5714ee50bb copy_xstate_to_kernel: Fix typo which caused GDB regression
This fixes a regression encountered while running the
gdb.base/corefile.exp test in GDB's test suite.

In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area.  Thus the
correct mask corresponding to XCR0 was not present in the core file for
GDB to interrogate, resulting in the following behavior:

   [kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
   Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...

   - A timer which is already expired at enqueue time can set the

   - When a timer is queued with an expiry time beyond the wheel

     level which is expiring last.

     The code adjusted the expiry time to the maximum wheel capacity,
     which is only correct when the wheel clock is 0. Aside of that the
     check whether the delta is larger than wheel capacity does not
     check the delta, it checks the expiry value itself. As a result
     timers can expire at random.

Pull irq fixes from Thomas Gleixner:
 "Two fixes for the interrupt subsystem:

   - Make the handling of the firmware node consistent and do not free
     the node after the domain has been created successfully. The core
     code stores a pointer to it which can lead to a use after free or
     double free.

     This used to "work" because the pointer was not stored when the
     initial code was written, but at some point later it was required
     to store it. Of course nobody noticed that the existing users break
     that way.

   - Handle affinity setting on inactive interrupts correctly when
     hierarchical irq domains are enabled.

     When interrupts are inactive with the modern hierarchical irqdomain
     design, the interrupt chips are not necessarily in a state where
     affinity changes can be handled. The legacy irq chip design allowed
     this because interrupts are immediately fully initialized at
     allocation time. X86 has a hacky workaround for this, but other
     implementations do not.

     This cased malfunction on GIC-V3. Instead of playing whack a mole
     to find all affected drivers, change the core code to store the
     requested affinity setting and then establish it when the interrupt
     is allocated, which makes the X86 hack go away"

0d6db85131 Revert "media: atomisp: keep the ISP powered on when setting it"
changeset d0213061a501 ("media: atomisp: fix mask and shift operation on ISPSSPM0")
solved the existing issue with the IUNIT power on code.

So, the driver can now use the right code again.

This reverts commit 95d1f398c4.

23988c9704 media: atomisp: fix mask and shift operation on ISPSSPM0
Currently the check on bits 25:24 on ISPSSPM0 is always 0 because
the mask and shift operations are incorrect. Fix this by shifting
by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking
with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits
to check.

da05b143a3 x86/boot: Don't add the EFI stub to targets
vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.

This confuses Makefile.build which interprets the EFI stub as a target
	$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]

Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.

[0] See scripts/Makefile.build near the end:
    # Create directories for object files if they do not exist

58ac3154b8 x86/entry: Actually disable stack protector
Some builds of GCC enable stack protector by default. Simply removing
the arguments is not sufficient to disable stack protector, as the stack
protector for those GCC builds must be explicitly disabled. Remove the
argument removals and add -fno-stack-protector. Additionally include
missed x32 argument updates, and adjust whitespace for readability.

85ebb8eb12 media: atomisp: move system_local consts into a C file
Instead of declaring all those consts everywhere when the
headers are included, just place them on a single place.

This change shuts up lots of warnings when built with W=1:

So, remove code duplication.

4b28ded763 media: atomisp: move global stuff into a common header
Right now, there are two versions of system_global.h headers.

Both share a lot of common code. There are some ISP2401 specific
types on one of the headers, but it doesn't conflict with the
ISP2400 ones.

Also, the common code is identical.

So, remove code duplication by moving such code into a
common header.

a6154805d0 media: atomisp: remove non-used 32-bits consts at system_local
There is an abstraction at the code in order to support
32 or 64 bits address/data length. However, for all
Atom chipsets supported by this version, the size is fixed.

So, cleanup the mess, removing the uused code and placing
the data sizes on a single place.

The end goal is to completely remove those local/global
headers, replacing them by some ISP-version dependent struct,
in order for the driver to decide what version it would need
in runtime.

c66ef39eb2 hwmon: (drivetemp) Avoid SCT usage on Toshiba DT01ACA family drives
It has been observed that Toshiba DT01ACA family drives have
WRITE FPDMA QUEUED command timeouts and sometimes just freeze until
power-cycled under heavy write loads when their temperature is getting
polled in SCT mode. The SMART mode seems to be fine, though.

Let's make sure we don't use SCT mode for these drives then.

While only the 3 TB model was actually caught exhibiting the problem let's
play safe here to avoid data corruption and extend the ban to the whole
family.

cadfad8701 x86/ioperm: Fix io bitmap invalidation on Xen PV
tss_invalidate_io_bitmap() wasn't wired up properly through the pvop
machinery, so the TSS and Xen's io bitmap would get out of sync
whenever disabling a valid io bitmap.

Add a new pvop for tss_invalidate_io_bitmap() to fix it.

This is XSA-329.

Fixes: 22fe5b0439 ("x86/ioperm: Move TSS bitmap update to exit to user work")

e8b4a890ed media: atomisp: Get rid of ACPI specifics in gmin_subdev_add()
First of all ACPI HID is a part of the device name which is printed
as a part of the dev_info(dev, ...); line. Second, since the only BID
is left, it's a part of ACPI path, which can be printed via %pfw.

Besides that, drop ACPI handle from atomisp_get_acpi_power() parameters.
