Removing the callback also enables us to remove the sh_mmcif_get_cd()
altogether, as we convert to use mmc_gpio_get_cd() to the same kind of

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree, most relevantly they are:
1) Extend nft_exthdr to allow to match TCP options bitfields, from
Manuel Messner.
2) Allow to check if IPv6 extension header is present in nf_tables,
from Phil Sutter.
3) Allow to set and match conntrack zone in nf_tables, patches from
Florian Westphal.
4) Several patches for the nf_tables set infrastructure, this includes
cleanup and preparatory patches to add the new bitmap set type.
5) Add optional ruleset generation ID check to nf_tables and allow to
delete rules that got no public handle yet via NFTA_RULE_ID. These
patches add the missing kernel infrastructure to support rule
deletion by description from userspace.
6) Missing NFT_SET_OBJECT flag to select the right backend when sets
stores an object map.
7) A couple of cleanups for the expectation and SIP helper, from Gao
feng.

If BPF_F_ALLOW_OVERRIDE flag is used in BPF_PROG_ATTACH command
to the given cgroup the descendent cgroup will be able to override
effective bpf program that was inherited from this cgroup.
By default it's not passed, therefore override is disallowed.
Examples:
1.
prog X attached to /A with default
prog Y fails to attach to /A/B and /A/B/C
Everything under /A runs prog X
2.
prog X attached to /A with allow_override.
prog Y fails to attach to /A/B with default (non-override)
prog M attached to /A/B with allow_override.
Everything under /A/B runs prog M only.
3.
prog X attached to /A with allow_override.
prog Y fails to attach to /A with default.
The user has to detach first to switch the mode.
In the future this behavior may be extended with a chain of
non-overridable programs.
Also fix the bug where detach from cgroup where nothing is attached
was not throwing error. Return ENOENT in such case.
Add several testcases and adjust libbpf.

This patch allows userspace to specify the generation ID that has been
used to build an incremental batch update.
If userspace specifies the generation ID in the batch message as
attribute, then nfnetlink compares it to the current generation ID so
you make sure that you work against the right baseline. Otherwise, bail
out with ERESTART so userspace knows that its changeset is stale and
needs to respin. Userspace can do this transparently at the cost of
taking slightly more time to refresh caches and rework the changeset.
This check is optional, if there is no NFNL_BATCH_GENID attribute in the
batch begin message, then no check is performed.

Requiring contiguous kernel memory is not a good idea, this is a limited
resource and allocation can fail under normal work loads.
This introduces a .write_sg op that supporting drivers can provide
to DMA directly from dis-contiguous memory and a new entry point
fpga_mgr_buf_load_sg that users can call to directly provide page
lists.
The full matrix of compatibility is provided, either the linear or sg
interface can be used by the user with a driver supporting either
interface.
A notable change for drivers is that the .write op can now be called
multiple times.

This patch renames the SPINOR_OP_* macros of the 4-byte address
instruction set so the new names all share a common pattern: the 4-byte
address name is built from the 3-byte address name appending the "_4B"
suffix.
The patch also introduces new op codes to support other SPI protocols such
as SPI 1-4-4 and SPI 1-2-2.
This is a transitional patch and will help a later patch of spi-nor.c
to automate the translation from the 3-byte address op codes into their
4-byte address version.

While supporting file-based address filters for CPU events requires some
extra context switch handling, kernel address filters are easy, since the
kernel mapping is preserved across address spaces. It is also useful as
it permits tracing scheduling paths of the kernel.
This patch allows setting up kernel filters for CPU events.
