commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in C")
reimplemented book3S code to pltform/powernv/idle.c. But when doing so
missed to add the per-thread LDBAR update in the core_woken path of
the power9_idle_stop(). Patch fixes the same.

Limit the size of the struct blk_zone array used in
blk_revalidate_disk_zones() to avoid memory allocation failures leading
to disk revalidation failure. Also further reduce the likelyhood of
such failures by using kvcalloc() (that is vmalloc()) instead of
allocating contiguous pages with alloc_pages().

During disk scan and revalidation done with sd_revalidate(), the zones
of a zoned disk are checked using the helper function
blk_revalidate_disk_zones() if a configuration change is detected
(change in the number of zones or zone size). The function
blk_revalidate_disk_zones() issues report_zones calls that are very
large, that is, to obtain zone information for all zones of the disk
with a single command. The size of the report zones command buffer
necessary for such large request generally is lower than the disk
max_hw_sectors and KMALLOC_MAX_SIZE (4MB) and succeeds on boot (no
memory fragmentation), but often fail at run time (e.g. hot-plug
event). This causes the disk revalidation to fail and the disk
capacity to be changed to 0.
This problem can be avoided by using vmalloc() instead of kmalloc() for
the buffer allocation. To limit the amount of memory to be allocated,
this patch also introduces the arbitrary SD_ZBC_REPORT_MAX_ZONES
maximum number of zones to report with a single report zones command.
This limit may be lowered further to satisfy the disk max_hw_sectors
limit. Finally, to ensure that the vmalloc-ed buffer can always be
mapped in a request, the buffer size is further limited to at most
queue_max_segments() pages, allowing successful mapping of the buffer
even in the worst case scenario where none of the buffer pages are
contiguous.

Only GFP_KERNEL and GFP_NOIO are used with blkdev_report_zones(). In
preparation of using vmalloc() for large report buffer and zone array
allocations used by this function, remove its "gfp_t gfp_mask" argument
and rely on the caller context to use memalloc_noio_save/restore() where
necessary (block layer zone revalidation and dm-zoned I/O error path).

To allow the SCSI subsystem scsi_execute_req() function to issue
requests using large buffers that are better allocated with vmalloc()
rather than kmalloc(), modify bio_map_kern() to allow passing a buffer
allocated with vmalloc().
To do so, detect vmalloc-ed buffers using is_vmalloc_addr(). For
vmalloc-ed buffers, flush the buffer using flush_kernel_vmap_range(),
use vmalloc_to_page() instead of virt_to_page() to obtain the pages of
the buffer, and invalidate the buffer addresses with
invalidate_kernel_vmap_range() on completion of read BIOs. This last
point is executed using the function bio_invalidate_vmalloc_pages()
which is defined only if the architecture defines
ARCH_HAS_FLUSH_KERNEL_DCACHE_PAGE, that is, if the architecture
actually needs the invalidation done.

In bio_integrity_prep(), a kernel buffer is allocated through kmalloc() to
hold integrity metadata. Later on, the buffer will be attached to the bio
structure through bio_integrity_add_page(), which returns the number of
bytes of integrity metadata attached. Due to unexpected situations,
bio_integrity_add_page() may return 0. As a result, bio_integrity_prep()
needs to be terminated with 'false' returned to indicate this error.
However, the allocated kernel buffer is not freed on this execution path,
leading to a memory leak.
To fix this issue, free the allocated buffer before returning from
bio_integrity_prep().

Pull SCSI scatter-gather list updates from James Bottomley:
"This topic branch covers a fundamental change in how our sg lists are
allocated to make mq more efficient by reducing the size of the
preallocated sg list.
This necessitates a large number of driver changes because the
previous guarantee that if a driver specified SG_ALL as the size of
its scatter list, it would get a non-chained list and didn't need to
bother with scatterlist iterators is now broken and every driver
*must* use scatterlist iterators.
This was broken out as a separate topic because we need to convert all
the drivers before pulling the trigger and unconverted drivers kept
being found, necessitating a rebase"

Following discussion on linux-next, we believe our version to be more
accurate than the one in the tree, so the resolution is to take our
version for all the SPDX conflicts"
Note on the SPDX license tag conversion conflicts: the SCSI tree had
done its own SPDX conversion, which in some cases conflicted with the
treewide ones done by Thomas & co.
In almost all cases, the conflicts were purely syntactic: the SCSI tree
used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
treewide conversion had used the new-style ones ("GPL-2.0-only" and
"GPL-2.0-or-later").
In these cases I picked the new-style one.
In a few cases, the SPDX conversion was actually different, though. As
explained by James above, and in more detail in a pre-pull-request
thread:
"The other problem is actually substantive: In the libsas code Luben
Tuikov originally specified gpl 2.0 only by dint of stating:
* This file is licensed under GPLv2.
In all the libsas files, but then muddied the water by quoting GPLv2
verbatim (which includes the or later than language). So for these
files Christoph did the conversion to v2 only SPDX tags and Thomas
converted to v2 or later tags"
So in those cases, where the spdx tag substantially mattered, I took the
SCSI tree conversion of it, but then also took the opportunity to turn
the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.
Similarly, when there were whitespace differences or other differences
to the comments around the copyright notices, I took the version from
the SCSI tree as being the more specific conversion.
Finally, in the spdx conversions that had no conflicts (because the
treewide ones hadn't been done for those files), I just took the SCSI
tree version as-is, even if it was old-style. The old-style conversions
are perfectly valid, even if the "-only" and "-or-later" versions are
perhaps more descriptive.

Fix the following compiler warning:
In function ‘esw_vport_add_ingress_acl_modify_metadata’:
the frame size of 1084 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Since the structure is never written to, we can statically allocate
it to avoid the stack usage.

In mlx5e_setup_tc "priv" variable is not being used if
CONFIG_MLX5_ESWITCH is off, one way to fix this is to actually use it.
mlx5e_setup_tc_mqprio also needs the "priv" variable and it extracts it
on its own. We can simply pass priv to mlx5e_setup_tc_mqprio instead of
netdev and avoid extracting the priv var, which will also resolve the
compiler warning.

we took care of IPv6 flowlabel reflections for two cases.
This patch takes care of the remaining case, when the RST packet

In Marek use case, this was a socket in TCP_CLOSE state.

Switching from ->priv_destructor to dellink() has an unexpected
consequence: existing RCU readers, that is, hsr_port_get_hsr()
callers, may still be able to read the port list.
Instead of checking the return value of each hsr_port_get_hsr(),
we can just move it to ->ndo_uninit() which is called after
device unregister and synchronize_net(), and we still have RTNL
lock there.

drm/imx: IPUv3 image converter improvements, enable scanout FIFO watermark
- Fix a saturation bit position in the colorspace converter
configuration memory.
- Fully describe colorspace conversions in the API to the imx-media driver.
- Add support for limited range and Rec.709 YUV encoding.
- Enable colorimetry configuration via the media-controller API.
- Enable the double write reduction feature for memory bandwidth savings
when the image converter writes YUV 4:2:0 output.
- Enable a scanout FIFO watermark feature that can increase priority of
scanout read transfers at the memory controller whenever the FIFO runs
low.

Pull x86 fixes from Thomas Gleixner:
"A collection of assorted fixes:
- Fix for the pinned cr0/4 fallout which escaped all testing efforts
because the kvm-intel module was never loaded when the kernel was
compiled with CONFIG_PARAVIRT=n. The cr0/4 accessors are moved out
of line and static key is now solely used in the core code and
therefore can stay in the RO after init section. So the kvm-intel
and other modules do not longer reference the (read only) static
key which the module loader tried to update.
- Prevent an infinite loop in arch_stack_walk_user() by breaking out
of the loop once the return address is detected to be 0.
- Prevent the int3_emulate_call() selftest from corrupting the stack
when KASAN is enabled. KASASN clobbers more registers than covered
by the emulated call implementation. Convert the int3_magic()
selftest to a ASM function so the compiler cannot KASANify it.
- Unbreak the build with old GCC versions and with the Gold linker by
reverting the 'Move of _etext to the actual end of .text'. In both
cases the build fails with 'Invalid absolute R_X86_64_32S
relocation: _etext'
- Initialize the context lock for init_mm, which was never an issue
until the alternatives code started to use a temporary mm for
patching.
- Fix a build warning vs. the LOWMEM_PAGES constant where clang
complains rightfully about a signed integer overflow in the shift
operation by converting the operand to an ULL.
- Adjust the misnamed ENDPROC() of common_spurious in the 32bit entry
code"
