SBC4 specifies that WRITE SAME requests with the UNMAP bit set to zero
"shall perform the specified write operation to each LBA specified by the
command". Commit 2237498f0b ("target/iblock: Convert WRITE_SAME to
blkdev_issue_zeroout") modified the iblock backend to call
blkdev_issue_zeroout() when handling WRITE SAME requests with UNMAP=0 and a
zero data segment.
The iblock blkdev_issue_zeroout() call incorrectly provides a flags
parameter of 0 (bool false), instead of BLKDEV_ZERO_NOUNMAP. The bool
false parameter reflects the blkdev_issue_zeroout() API prior to commit
ee472d835c ("block: add a flags argument to (__)blkdev_issue_zeroout")
which was merged shortly before 2237498f0b.

qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the
completion of these async commands. If UNLOADING is set, this is doomed to
timeout, because the async logout command will never complete.
The only way to avoid waiting pointlessly is to fail posting these commands
in the first place if the driver is in UNLOADING state. In general,
posting any command should be avoided when the driver is UNLOADING.
With this patch, "rmmod qla2xxx" completes without noticeable delay.

The purpose of the UNLOADING flag is to avoid port login procedures to
continue when a controller is in the process of shutting down. It makes
sense to set this flag before starting session teardown.
Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run
multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the
test for UNLOADING is postponed until after the check for an already
disabled PCI board.

The APIs scsi_host_block()/scsi_host_unblock() were recently added by

("scsi: aacraid: use scsi_host_(block,unblock) to block I/O").
However, from reading the code, I think the APIs don't really work for

scsi_host_block() is called, scsi_device_quiesce() has set the state to
SDEV_QUIESCE, so aac_suspend() -> scsi_host_block() returns -EINVAL.

During the process of debugging a processor derived from the msm8916 which
we found the new processor was not starting one of its PLLs.
After tracing the addresses and writes that downstream was doing and
comparing to upstream it became obvious that we were writing to a different
register location than downstream when trying to configure the PLL.
This error is also present in upstream msm8916.
As an example clk-pll.c::clk_pll_recalc_rate wants to write to
pll->config_reg updating the bit-field POST_DIV_RATIO. That bit-field is
defined in PLL_USER_CTL not in PLL_CONFIG_CTL. Taking the BIMC PLL as an
example
lm80-p0436-13_c_qc_snapdragon_410_processor_hrd.pdf
0x01823010 GCC_BIMC_PLL_USER_CTL
0x01823014 GCC_BIMC_PLL_CONFIG_CTL
This pattern is repeated for gpll0, gpll1, gpll2 and bimc_pll.
This error is likely not apparent since the bootloader will already have
initialized these PLLs.
This patch corrects the location of config_reg from PLL_CONFIG_CTL to
PLL_USER_CTL for all relevant PLLs on msm8916.

====================
Support programmable pins for Ocelot PTP driver
The Ocelot PTP clock driver had been embedded into ocelot.c driver.
It had supported basic gettime64/settime64/adjtime/adjfine functions
by now which were used by both Ocelot switch and Felix switch.
This patch-set is to move current ptp clock code out of ocelot.c driver
maintaining as a single ocelot_ptp.c driver, and to implement 4
programmable pins with only PTP_PF_PEROUT function for now.
The PTP_PF_EXTTS function will be supported in the future, and it should
be implemented separately for Felix and Ocelot, because of different
hardware interrupt implementation in them.
Changes for v2:
- Put PTP driver under drivers/net/ethernet/mscc/.
- Dropped MAINTAINERS patch. Kept original maintaining.
- Initialized PTP separately in ocelot/felix platforms.
- Supported PPS case in programmable pin.
- Supported disabling pin function since deadlock is fixed by Richard.
- Returned -EBUSY if not finding pin available.

- Re-sent.

When building with the LLVM linker this error occurrs:

This happens because the lld treats -R as an alias to -rpath, as opposed
to ld where -R means --just-symbols.
Use the long option name for compatibility between the two.

Currently the SoC revision attribute for Tegra devices displays the
value of the enum associated with a particular revision. This is not
very useful because to obtain the actual revision you need to
use the tegra_revision enumeration to translate the value.
It is more meaningful to display a name for the revision, such as
'A01', than the enumarated value and therefore, update the revision
attribute to display a name. This change does alter the ABI, which
is unfortunate, but this is more meaningful and maintable.

Add a custom SoC attribute for Tegra to expose the HIDREV register
fields to userspace via the sysfs. This register provides additional
details about the type of device (eg, silicon, FPGA, etc) as well as
revision. Exposing this information is useful for identifying the
exact device revision and device type.
For Tegra devices up until Tegra186, the majorrev and minorrev fields of
the HIDREV register are used to determine the device revision and device
type. For Tegra194, the majorrev and minorrev fields only determine the
revision. Starting with Tegra194, there is an additional field,
pre_si_platform (which occupies bits 20-23), that now determines device
type. Therefore, for all Tegra devices, add a custom SoC attribute for
the majorrev and minorrev fields and for Tegra194 add an additional
attribute for the pre_si_platform field.

The Tegra BPMP driver typically ends up deferring probe because it wants
to attach to the SMMU, so there's little sense in registering it at the
core init-level.
One side-effect of this is that the driver will be probed later even if
it doesn't want to attach to an SMMU, which means that consumers will
end up deferring probe, which in turn takes care of ordering the suspend
and resume queue in the correct way. Currently since suspend/resume
order depends on instantiation order, and because BPMP is listed at the
very end of the device tree (after most of its consumers), the suspend
and resume queue is ordered wrongly, which can cause issues for drivers
(like I2C) which suspend after and resume before BPMP. In the case of
I2C this typically leads to the clock failing to enable.
Besides fixing this suspend/resume ordering issue, this also has the
added benefit of allowing the driver to be built as a loadable module,
which can help decrease the size of multiplatform kernel.

Leon Romanovsky says:
====================
Remove vermagic header from global include folder
Changelog:
v2:
* Changed the implementation of patch #4 to be like Masahiro wants.
I personally don't like this implementation and changing it just to move forward
this this patchset.
v1:
https://lore.kernel.org/lkml/20200415133648.1306956-1-leon@kernel.org
* Added tags
* Updated patch #4 with test results
* Changed scripts/mod/modpost.c to create inclusion of vermagic.h
from kernel folder and not from general include/linux. This is
needed to generate *.mod.c files, while building modules.
v0:
https://lore.kernel.org/lkml/20200414155732.1236944-1-leon@kernel.org
This is followup to the failure reported by Borislav [1] and suggested
fix later on [2].
The series removes all includes of linux/vermagic.h, updates hns and
nfp to use same kernel versioning scheme (exactly like we did for
other drivers in previous cycle) and removes vermagic.h from global
include folder.

VERMAGIC* definitions are not supposed to be used by the drivers,
see this [1] bug report, so introduce special define to guard inclusion
of this header file and define it in kernel/modules.h and in internal
script that generates *.mod.c files.
In-tree module build:
➜ kernel git:(vermagic) ✗ make clean

➜ kernel git:(vermagic) ✗ modinfo drivers/infiniband/hw/mlx5/mlx5_ib.ko

vermagic: 5.6.0+ SMP mod_unload modversions
Out-of-tree module build:
➜ mlx5 make -C /images/leonro/src/kernel clean M=/tmp/mlx5
➜ mlx5 make -C /images/leonro/src/kernel M=/tmp/mlx5
➜ mlx5 modinfo /tmp/mlx5/mlx5_ib.ko

Get rid of linux/vermagic.h includes, so that MODULE_ARCH_VERMAGIC from
the arch header arch/x86/include/asm/module.h won't be redefined.
