This driver was added by commit 0fc6a323e1917 ("spi: bcm53xx: driver for
SPI controller on Broadcom bcma SoC") back in 2014. It was needed to
provide a minimal support for SPI controller on BCM5301X (AKA Northstar)
devices.
An alternative driver was added by Kamal in commit fa236a7ef2404 ("spi:
bcm-qspi: Add Broadcom MSPI driver") 2 years later. It supports the same
hardware but for some reason a new driver has been developed for it.
At this point the new driver supports: more modes, setting a speed,
setting bits per word and uses IRQs instead of polling. DTS file for
BCM5301X has also been updated in the commit 1c8f406507238 ("ARM: dts:
BCM5301X: convert to iProc QSPI") - over a year ago.
That explained I see no reason to keep the old driver alive.

When removing a rule that jumps to chain and such chain in the same

currently matchinfo gets stored in the expression, but some xt matches
are very large.
To handle those we either need to switch nft core to kvmalloc and increase
size limit, or allocate the info blob of large matches separately.
This does the latter, this limits the scope of the changes to
nft_compat.
I picked a threshold of 192, this allows most matches to work as before and
handle only few ones via separate alloation (cgroup, u32, sctp, rt).

Next patch will make it possible for *info to be stored in
a separate allocation instead of the expr private area.
This removes the 'expr priv area is info blob' assumption
from the match init/destroy/eval functions.

swiotlb now selects the DMA_DIRECT_OPS config symbol, so this will

This way we have one central definition of it, and user can select it as
needed. The new option is not user visible, which is the behavior
it had in most architectures, with a few notable exceptions:
- On x86_64 and mips/loongson3 it used to be user selectable, but
defaulted to y. It now is unconditional, which seems like the right
thing for 64-bit architectures without guaranteed availablity of
IOMMUs.
- on powerpc the symbol is user selectable and defaults to n, but
many boards select it. This change assumes no working setup
required a manual selection, but if that turned out to be wrong
we'll have to add another select statement or two for the respective
boards.

Define this symbol if the architecture either uses 64-bit pointers or the
PHYS_ADDR_T_64BIT is set. This covers 95% of the old arch magic. We only
need an additional select for Xen on ARM (why anyway?), and we now always
set ARCH_DMA_ADDR_T_64BIT on mips boards with 64-bit physical addressing
instead of only doing it when highmem is set.

Since commit a92a08499b1f "r8169: improve runtime pm in general and
suspend unused ports" interfaces w/o link are runtime-suspended after
10s. On systems where drivers take longer to load this can lead to the
situation that the interface is runtime-suspended already when it's
initially brought up.
This shouldn't be a problem because rtl_open() resumes MAC/PHY.
However with at least one chip version the interface doesn't properly
come up, as reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=199549
The vendor driver uses a delay to give certain chip versions some
time to resume before starting the PHY configuration. So let's do
the same. I don't know which chip versions may be affected,
therefore apply this delay always.
This patch was reported to fix the issue for RTL8168h.
I was able to reproduce the issue on an Asus H310I-Plus which also
uses a RTL8168h. Also in my case the patch fixed the issue.
