There are two drivers in the cs89x0 file, with the CONFIG_CS89x0_PLATFORM
symbol deciding which one is getting built. This is somewhat confusing
and makes it more likely ton configure a driver that works nowhere.
Split up the Kconfig option into separate ISA and PLATFORM drivers,
with the ISA symbol explicitly connecting to the static probing in
drivers/net/Space.c
The two drivers are still mutually incompatible at compile time,
which could be lifted by splitting them into multiple files,
but in practice this will make no difference.
The platform driver can now be enabled for compile-testing on
non-ARM machines.

The current maximum RX ring size is defined assuming the RX jumbo ring
(aka aggregation ring) is used. The RX jumbo ring is automicatically used
when the MTU exceeds a threshold or when rx-gro-hw/lro is enabled. The RX
jumbo ring is automatically sized up to 4 times the size of the RX ring
size.
The BNXT_MAX_RX_DESC_CNT constant is the upper limit on the size of the
RX ring whether or not the RX jumbo ring is used. Obviously, the
maximum amount of RX buffer space is significantly less when the RX jumbo
ring is not used.
To increase flexibility for the user who does not use the RX jumbo ring,
we now define a bigger maximum RX ring size when the RX jumbo ring is not
used. The maximum RX ring size is now up to 8K when the RX jumbo ring
is not used. The maximum completion ring size also needs to be scaled
up to accomodate the larger maximum RX ring size.
Note that when the RX jumbo ring is re-enabled, the RX ring size will
automatically drop if it exceeds the maximum.

We currently store these page addresses and DMA addreses in static
arrays. On systems with 4K pages, we support up to 64 pages per
completion ring. The actual number of pages for each completion ring
may be much less than 64. For example, when the RX ring size is set
to the default 511 entries, only 16 completion ring pages are needed
per ring.
In the next patch, we'll be doubling the maximum number of completion
pages. So we convert to allocate these arrays as needed instead of
declaring them statically.

When running command pipelining for WRITE direction commands (e.g. tape
device write), userspace sends cmd completion to cmd ring before processing
write data. In that case userspace has to copy data before sending
completion, because cmd completion also implicitly releases the data buffer
in data area.
The new feature KEEP_BUF allows userspace to optionally keep the buffer
after completion by setting new bit TCMU_UFLAG_KEEP_BUF in
tcmu_cmd_entry_hdr->uflags. In that case buffer has to be released
explicitly by writing the cmd_id to new action item free_kept_buf.
All kept buffers are released during reset_ring and if userspace closes uio
device (tcmu_release).

I saw the build failure that was fixed in commit 6387f65e2acb ("net:

issue that was introduced in the same patch: Using GENMASK() to
create a 64-bit mask does not work on 32-bit architectures.
This probably won't ever happen on this driver since it's specific
to a 64-bit SoC, but it's better to write it portably, so use
GENMASK_ULL() instead.

Saeed Mahameed says:
====================
This patch-set changes the TTC (Traffic Type Classification) logic
to be independent from the mlx5 ethernet driver by renaming the traffic
types enums and making the TTC API generic to the mlx5 core driver.
It allows to decouple TTC logic from mlx5e and reused by other parts
of mlx5 drivers, namely ADQ and lag TX steering hashing.
Patches overview:
1 - Rename traffic type enums to be mlx5 generic.
2 - Rename related TTC arguments and functions.
3 - Remove dependency in the mlx5e driver from the TTC implementation.
4 - Move TTC logic to fs_ttc.
5 - Embed struct mlx5_ttc_table in fs_ttc.
The refactoring series is followed by misc' cleanup patches.

On arm64, the stub only moves the kernel image around in memory if
needed, which is typically only for KASLR, given that relocatable
kernels (which is the default) can run from any 64k aligned address,
which is also the minimum alignment communicated to EFI via the PE/COFF
header.
Unfortunately, some loaders appear to ignore this header, and load the
kernel at some arbitrary offset in memory. We can deal with this, but
let's check for this condition anyway, so non-compliant code can be
spotted and fixed.

Randomization of the physical load address of the kernel image relies on
efi_random_alloc() returning successfully, and currently, we ignore any
failures and just carry on, using the ordinary, non-randomized page
allocator routine. This means we never find out if a failure occurs,
which could harm security, so let's at least warn about this condition.

Commit 82046702e288 ("efi/libstub/arm64: Replace 'preferred' offset with
alignment check") simplified the way the stub moves the kernel image
around in memory before booting it, given that a relocatable image does
not need to be copied to a 2M aligned offset if it was loaded on a 64k
boundary by EFI.
Commit d32de9130f6c ("efi/arm64: libstub: Deal gracefully with
EFI_RNG_PROTOCOL failure") inadvertently defeated this logic by
overriding the value of efi_nokaslr if EFI_RNG_PROTOCOL is not
available, which was mistaken by the loader logic as an explicit request
on the part of the user to disable KASLR and any associated relocation
of an Image not loaded on a 2M boundary.
So let's reinstate this functionality, by capturing the value of
efi_nokaslr at function entry to choose the minimum alignment.

Distro versions of GRUB replace the usual LoadImage/StartImage calls
used to load the kernel image with some local code that fails to honor
the allocation requirements described in the PE/COFF header, as it
does not account for the image's BSS section at all: it fails to
allocate space for it, and fails to zero initialize it.
Since the EFI stub itself is allocated in the .init segment, which is
in the middle of the image, its BSS section is not impacted by this,
and the main consequence of this omission is that the BSS section may
overlap with memory regions that are already used by the firmware.
So let's warn about this condition, and force image reallocation to
occur in this case, which works around the problem.
