Unlike x86, which has machinery to deal with page faults that occur
during the execution of EFI runtime services, arm64 has nothing like
that, and a synchronous exception raised by firmware code brings down
the whole system.

With more EFI based systems appearing that were not built to run Linux
(such as the Windows-on-ARM laptops based on Qualcomm SOCs), as well as
the introduction of PRM (platform specific firmware routines that are
callable just like EFI runtime services), we are more likely to run into
issues of this sort, and it is much more likely that we can identify and
work around such issues if they don't bring down the system entirely.

Since we already use a EFI runtime services call wrapper in assembler,
we can quite easily add some code that captures the execution state at
the point where the call is made, allowing us to revert to this state
and proceed execution if the call triggered a synchronous exception.

Given that the kernel and the firmware don't share any data structures
that could end up in an indeterminate state, we can happily continue
running, as long as we mark the EFI runtime services as unavailable from
that point on.

The following commands should result in all the dynamic FDB entries
being flushed, but instead all the non-local (non-permanent) entries are
flushed:

 # bridge fdb add 00:aa:bb:cc:dd:ee dev dummy1 master static
 # bridge fdb add 00:11:22:33:44:55 dev dummy1 master dynamic
 # ip link set dev br0 type bridge fdb_flush

 33:33:00:00:00:01 self permanent

This is because br_fdb_flush() works with FDB flags and not the
corresponding enumerator values. Fix by passing the FDB flag instead.

Netfilter/IPVS fixes for net

1) netlink socket notifier might win race to release objects that are
   already pending to be released via commit release path, reported by
   syzbot.

2) No need to postpone flow rule release to commit release path, this
   triggered the syzbot report, complementary fix to previous patch.

3) Use explicit signed chars in IPVS to unbreak arm, from Jason A. Donenfeld.

4) Missing check for proc entry creation failure in IPVS, from Zhengchao Shao.

5) Incorrect error path handling when BPF NAT fails to register, from
   Chen Zhongjin.

6) Prevent huge memory allocation in ipset hash types, from Jozsef Kadlecsik.

Except the incorrect BPF NAT error path which is broken in 6.1-rc, anything
else has been broken for several releases.

[Why]
Certain 4K high refresh rate modes requiring DSC are exhibiting top
of screen underflow corruption. Increasing the DSC delay by a factor
of 6 percent stops the underflow for most use cases.

[How]
Multiply DSC delay requirement in DML by a factor.
Add debug option to make this DSC delay factor configurable.

The recent change brought a bug on SRIOV envrionment. It caused
unloading amdgpu failed on Guest VM. The reason is that the VF
FLR was requested while unloading amdgpu driver, but the VF FLR
of SRIOV sequence is wrong while removing PCI device.

For SRIOV, the guest driver should not trigger the whole XGMI hive
to do the reset. Host driver control how the device been reset.

====================================

HCI core will uses hci_rx_work() to process frame, which is queued to
the hdev->rx_q tail in hci_recv_frame() by HCI driver.

Yet the problem is that, HCI core may not free the skb after handling
ACL data packets. To be more specific, when start fragment does not
contain the L2CAP length, HCI core just copies skb into conn->rx_skb and
finishes frame process in l2cap_recv_acldata(), without freeing the skb,
which triggers the above memory leak.

This patch solves it by releasing the relative skb, after processing
the above case in l2cap_recv_acldata().
