A few times in CI, we have detected a GPU hang on our Haswell GT2
systems with the characteristic IPEHR of 0x780c0000. When the PSMI w/a
was first introducted, it was applied to all Haswell, but later on we
found an erratum that supposedly restricted the issue to GT1 and so
constrained it only be applied on GT1. That may have been a mistake...

While srcu may use an integer tag, it does not exclude potential error
codes and so may overlap with our own use of -EINTR. Use a separate
outparam to store the tag, and report the error code separately.

This allows userspace to use "legacy" mode for push constants, where
they are committed at 3DPRIMITIVE or flush time, rather than being
committed at 3DSTATE_BINDING_TABLE_POINTERS_XS time. Gen6-8 and Gen11
both use the "legacy" behavior - only Gen9 works in the "new" way.
Conflating push constants with binding tables is painful for userspace,
we would like to be able to avoid doing so.

As soon as we re-enable the various functions within the HW, they may go
off and read data via a GGTT offset. Hence, if we have not yet restored
the GGTT PTE before then, they may read and even *write* random locations
in memory.

As we may unwind incomplete requests (for preemption) prior to
processing the CSB and the schedule-out events, we may update rq->engine
(resetting it to point back to the parent virtual engine) prior to
calling execlists_schedule_out(), invalidating the assertion that the
request still points to the inflight engine. (The likelihood of this is
increased if the CSB interrupt processing is pushed to the ksoftirqd for
being too slow and direct submission overtakes it.)
Tvrtko summarised it as:
"So unwind from direct submission resets rq->engine and races with
process_csb from the tasklet which notices request has actually
completed."

If __calc_tpm2_event_size() fails to parse an event it will return 0,
resulting tpm2_calc_event_log_size() returning -1. Currently there is
no check of this return value, and 'efi_tpm_final_log_size' can end up
being set to this negative value resulting in a crash like this one:
BUG: unable to handle page fault for address: ffffbc8fc00866ad
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
RIP: 0010:memcpy_erms+0x6/0x10

platform_drv_probe()
...
Also __calc_tpm2_event_size() returns a size of 0 when it fails
to parse an event, so update function documentation to reflect this.
The root cause of the issue that caused the failure of event parsing
in this case is resolved by Peter Jone's patchset dealing with large
event logs where crossing over a page boundary causes the page with
the event count to be unmapped.

When there are no entries to put into the final event log, some machines
will return the template they would have populated anyway. In this case
the nr_events field is 0, but the rest of the log is just garbage.
This patch stops us from trying to iterate the table with
__calc_tpm2_event_size() when the number of events in the table is 0.

The kernel command line option efivar_ssdt= allows the name to be
specified of an EFI variable containing an ACPI SSDT table that should
be loaded into memory by the OS, and treated as if it was provided by
the firmware.
Currently, that code will always iterate over the EFI variables and
compare each name with the provided name, even if the command line
option wasn't set to begin with.
So bail early when no variable name was provided. This works around a
boot regression on the 2012 Mac Pro, as reported by Scott.

Commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to
chip->read_xxx() hooks") modified the prototype of the struct nand_chip
read_buf function pointer. In the au1550nd driver we have 2
implementations of read_buf. The previously mentioned commit modified
the au_read_buf() implementation to match the function pointer, but not
au_read_buf16(). This results in a compiler warning for MIPS
db1xxx_defconfig builds:
drivers/mtd/nand/raw/au1550nd.c:443:57:
warning: pointer type mismatch in conditional expression
Fix this by updating the prototype of au_read_buf16() to take a struct
nand_chip pointer as its first argument, as is expected after commit
7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx()
hooks").
Note that this shouldn't have caused any functional issues at runtime,
since the offset of the struct mtd_info within struct nand_chip is 0
making mtd_to_nand() effectively a type-cast.

Read the PHY-specific status register for the current operating mode
(speed and duplex) of the PHY. This register reflects the actual
mode that the PHY has resolved depending on either the advertisements
of autoneg is enabled, or the forced mode if autoneg is disabled.
This ensures that phylib's software state always tracks the hardware
state.
It seems both AR8033 (which uses the AR8031 ID) and AR8035 support
this status register. AR8030 is not known at the present time.
This patch depends on "net: phy: extract pause mode" and "net: phy:
extract link partner advertisement reading".

When userspace writes to the MII_ADVERTISE register, we update phylib's
advertising mask and trigger a renegotiation. However, writing to the
MII_CTRL1000 register, which contains the gigabit advertisement, does
neither. This can lead to phylib's copy of the advertisement becoming
de-synced with the values in the PHY register set, which can result in
incorrect negotiation resolution.

mdio_device_reset() makes use of the atomic-pretending API flavor for
handling the PHY reset GPIO line.
I found no hint that mdio_device_reset() is called from atomic context
and indeed it uses usleep_range() since long time, so I would assume that
it is OK to sleep there.
This patch switch to gpiod_set_value_cansleep() in mdio_device_reset().
This is relevant if e.g. the PHY reset line is tied to a I2C GPIO
controller.
This has been tested on a ZynqMP board running an upstream 4.19 kernel and
then hand-ported on current kernel tree.

r8152 may fail to establish network connection after resume from system
suspend.
If the USB port connects to r8152 lost its power during system suspend,
the MAC address was written before is lost. The reason is that The MAC
address doesn't get written again in its reset_resume callback.
So let's set MAC address again in reset_resume callback. Also remove
unnecessary lock as no other locking attempt will happen during
reset_resume.

Commit 7fd8930f26be4
"nvme: add a common helper to read Identify Controller data"
has re-introduced an issue that we have attempted to work around in the
past, in commit a310acd7a7ea ("NVMe: use split lo_hi_{read,write}q").
The problem is that some PCIe NVMe controllers do not implement 64-bit
outbound accesses correctly, which is why the commit above switched
to using lo_hi_[read|write]q for all 64-bit BAR accesses occuring in
the code.
In the mean time, the NVMe subsystem has been refactored, and now calls
into the PCIe support layer for NVMe via a .reg_read64() method, which
fails to use lo_hi_readq(), and thus reintroduces the problem that the
workaround above aimed to address.
Given that, at the moment, .reg_read64() is only used to read the
capability register [which is known to tolerate split reads], let's
switch .reg_read64() to lo_hi_readq() as well.
This fixes a boot issue on some ARM boxes with NVMe behind a Synopsys
DesignWare PCIe host controller.

pins 32-35 spill over into the next register. The calculation
for the register address was done, but the bitmask was not, so
any configuration to pin 32 or above resulted in a bitmask that
overflowed and performed no action.
