Add a module parameter to control the AGP aperture. The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space. This access is non-snooped so only uncached memory
can be accessed.
Add a knob so that we can toggle this for debugging.

The section mismatch check prints a bogus symbol name on some
architectures.
[test code]
#include <linux/init.h>
int __initdata foo;
int get_foo(void) { return foo; }
If you compile it with GCC for riscv or loongarch, modpost will show an
incorrect symbol name:
WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> done (section: .init.data)
To get the correct symbol address, the st_value must be added.
This issue has never been noticed since commit 93684d3b80 ("kbuild:
include symbol names in section mismatch warnings") presumably because
st_value becomes zero on most architectures when the referenced symbol
is looked up. It is not true for riscv or loongarch, at least.
With this fix, modpost will show the correct symbol name:
WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> foo (section: .init.data)

Merge tag 'nf-23-11-15' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Remove unused variable causing compilation warning in nft_set_rbtree,
from Yang Li. This unused variable is a left over from previous
merge window.
2) Possible return of uninitialized in nf_conntrack_bridge, from
Linkui Xiao. This is there since nf_conntrack_bridge is available.
3) Fix incorrect pointer math in nft_byteorder, from Dan Carpenter.
Problem has been there since 2016.
4) Fix bogus error in destroy set element command. Problem is there
since this new destroy command was added.
5) Fix race condition in ipset between swap and destroy commands and
add/del/test control plane. This problem is there since ipset was
merged.
6) Split async and sync catchall GC in two function to fix unsafe
iteration over RCU. This is a fix-for-fix that was included in
the previous pull request.

Macvlan device in passthru mode sets its lower device promiscuous mode
according to its MACVLAN_FLAG_NOPROMISC flag instead of synchronizing it to
its own promiscuity setting. However, macvlan_change_rx_flags() function
doesn't check the mode before propagating such changes to the lower device
which can cause net_device->promiscuity counter overflow as illustrated by
reproduction example [0] and resulting dmesg log [1]. Fix the issue by
first verifying the mode in macvlan_change_rx_flags() function before
propagating promiscuous mode change to the lower device.

There is no hardware supporting ct helper offload. However, prior to this
patch, a flower filter with a helper in the ct action can be successfully
set into the HW, for example (eth1 is a bnxt NIC):
# tc qdisc add dev eth1 ingress_block 22 ingress
# tc filter add block 22 proto ip flower skip_sw ip_proto tcp \
dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp
# tc filter show dev eth1 ingress
filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1
eth_type ipv4
ip_proto tcp
dst_port 21
ct_state -trk
skip_sw
in_hw in_hw_count 1 <----
action order 1: ct zone 0 helper ipv4-tcp-ftp pipe
index 2 ref 1 bind 1
used_hw_stats delayed
This might cause the flower filter not to work as expected in the HW.
This patch avoids this problem by simply returning -EOPNOTSUPP in
tcf_ct_offload_act_setup() to not allow to offload flows with a helper
in act_ct.

icosq_str size is unnecessarily too long, and it causes a build warning
-Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B,
hence this patch reduces the size to 32B which should be more than enough
to host the string: "ICOSQ: 0x%x, ".
While here, add a missing space in the formatted string.

Previously, mlx5e_ptp_poll_ts_cq would update the device doorbell with the
incremented consumer index after the relevant software counters in the
kernel were updated. In the mlx5e_sq_xmit_wqe context, this would lead to
either overrunning the device CQ or exceeding the expected software buffer
size in the device CQ if the device CQ size was greater than the software
buffer size. Update the relevant software counter only after updating the
device CQ consumer index in the port timestamping napi_poll context.
