The mlx5 IPsec code has logical separation between code that operates
with XFRM objects (ipsec.c), HW objects (ipsec_offload.c), flow steering
logic (ipsec_fs.c) and data path (ipsec_rxtx.c).
Such separation makes sense for C-files, but isn't needed at all for
H-files as they are included in batch anyway.

mlx5 IPsec code updated ESN through workqueue with allocation calls
in the data path, which can be saved easily if the work is created
during XFRM state initialization routine.
The locking used later in the work didn't protect from anything because
change of HW context is possible during XFRM state add or delete only,
which can cancel work and make sure that it is not running.

The XFRM code performs fallback to software IPsec if .xdo_dev_state_add()
returns -EOPNOTSUPP. This is what mlx5 did very deep in its stack trace,
despite have all the knowledge that IPsec is not going to work in very
early stage.
This is achieved by making sure that priv->ipsec pointer is valid for
fully working and supported hardware crypto IPsec engine.
In case, the hardware IPsec is not supported, the XFRM code will set NULL
to xso->dev and it will prevent from calls to various .xdo_dev_state_*()
callbacks.

In bnxt_poll_p5(), we first check cpr->has_more_work. If it is true,
we are in NAPI polling mode and we will call __bnxt_poll_cqs() to
continue polling. It is possible to exhanust the budget again when
__bnxt_poll_cqs() returns.
We then enter the main while loop to check for new entries in the NQ.
If we had previously exhausted the NAPI budget, we may call
__bnxt_poll_work() to process an RX entry with zero budget. This will
cause packets to be dropped unnecessarily, thinking that we are in the
netpoll path. Fix it by breaking out of the while loop if we need
to process an RX NQ entry with no budget left. We will then exit
NAPI and stay in polling mode.

bnxt_open() can fail in this code path, especially on a VF when
it fails to reserve default rings:
bnxt_open()
__bnxt_open_nic()
bnxt_clear_int_mode()
bnxt_init_dflt_ring_mode()
RX rings would be set to 0 when we hit this error path.
It is possible for a subsequent bnxt_open() call to potentially succeed
with a code path like this:
bnxt_open()
bnxt_hwrm_if_change()
bnxt_fw_init_one()
bnxt_fw_init_one_p3()
bnxt_set_dflt_rfs()
bnxt_rfs_capable()
bnxt_hwrm_reserve_rings()
On older chips, RFS is capable if we can reserve the number of vnics that
is equal to RX rings + 1. But since RX rings is still set to 0 in this
code path, we may mistakenly think that RFS is supported for 0 RX rings.
Later, when the default RX rings are reserved and we try to enable
RFS, it would fail and cause bnxt_open() to fail unnecessarily.
We fix this in 2 places. bnxt_rfs_capable() will always return false if
RX rings is not yet set. bnxt_init_dflt_ring_mode() will call
bnxt_set_dflt_rfs() which will always clear the RFS flags if RFS is not
supported.

The AlphaProject AP-SH4A-3A/AP-SH4AD-0A SH boards use IRQ0 for their SMSC
LAN911x Ethernet chip, so the networking on them must have been broken by
commit 965b2aa78fbc ("net/smsc911x: fix irq resource allocation failure")
which filtered out 0 as well as the negative error codes -- it was kinda
correct at the time, as platform_get_irq() could return 0 on of_irq_get()
failure and on the actual 0 in an IRQ resource. This issue was fixed by
me (back in 2016!), so we should be able to fix this driver to allow IRQ0
usage again...
When merging this to the stable kernels, make sure you also merge commit
e330b9a6bb35 ("platform: don't return 0 from platform_get_irq[_byname]()
on error") -- that's my fix to platform_get_irq() for the DT platforms...

As noted elsewhere, various GPON SFP modules exhibit non-standard
TX-fault behaviour. In the tested case, the Huawei MA5671A, when used
in combination with a Marvell mv88e6085 switch, was found to
persistently assert TX-fault, resulting in the module being disabled.
This patch adds a quirk to ignore the SFP_F_TX_FAULT state, allowing the
module to function.

The discard_alignment queue limit is named a bit misleading means the
offset into the block device at which the discard granularity starts.
Setting it to PAGE_SIZE while the discard granularity is the block size
that is smaller or the same as PAGE_SIZE as done by dasd is mostly
harmless but also useless.

The discard_alignment queue limit is named a bit misleading means the
offset into the block device at which the discard granularity starts.
On the other hand the discard_sector_alignment from the virtio 1.1 looks
similar to what Linux uses as discard granularity (even if not very well
described):
"discard_sector_alignment can be used by OS when splitting a request
based on alignment. "
And at least qemu does set it to the discard granularity.
So stop setting the discard_alignment and use the virtio
discard_sector_alignment to set the discard granularity.

The USBPHY Control block is identical on Renesas RZ/G2L and RZ/V2L SoC's,
so instead of adding dependency for each SoC's add dependency on
ARCH_RZG2L. The ARCH_RZG2L config option is already selected by
ARCH_R9A07G044 and ARCH_R9A07G054.

Some of the IO devices like I2C or SPI require reset at runtime to
recover from an error condition without changing the power state of
the system. Added check for ACPI handle and a call to method '__RST'
if supported. Devices using device tree method are unaffected by this.

A reference to the framebuffer device struct fb_info is stored in the file
private data, but this reference could no longer be valid and must not be
accessed directly. Instead, the file_fb_info() accessor function must be
used since it does sanity checking to make sure that the fb_info is valid.
This can happen for example if the registered framebuffer device is for a
driver that just uses a framebuffer provided by the system firmware. In
that case, the fbdev core would unregister the framebuffer device when a
real video driver is probed and ask to remove conflicting framebuffers.
The bug has been present for a long time but commit 27599aacbaef ("fbdev:
Hot-unplug firmware fb devices on forced removal") unmasked it since the
fbdev core started unregistering the framebuffers' devices associated.
