Add a resource identifier for maximum number of FIDs so that it could be
later used to query the information from firmware.
In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are
sent as control packets is not updated at egress port. To overcome this
limitation, some packets will be sent as data packets. The header should
include FID, which is supposed to be 'Max FID + port - 1'. As preparation,
add the required resource, to be able to query the value from firmware
later.

Currently, the field FID in TX header is defined, but is not used as it is
relevant only for data packets. mlxsw driver currently sends all
host-generated traffic as control packets and not as data packets.
In Spectrum-2 and Spectrum-3, the correction field of PTP packets which
are sent as control packets is not updated at egress port. To overcome this
limitation while adding support for PTP, some packets will be sent as data
packets.

In Spectrum-2, all the packets are time stamped, the MTPCPC register is
used to configure the types of packets that will adjust the correction
field and which port will trap PTP packets.
If ingress correction is set on a port for a given packet type, then
when such a packet is received via the port, the current time stamp is
subtracted from the correction field.
If egress correction is set on a port for a given packet type, then when
such a packet is transmitted via the port, the current time stamp is
added to the correction field.
Assuming the systems is configured correctly, the above means that the
correction field will contain the transient delay between the ports.
Add this register for a future use in order to support PTP in Spectrum-2.

On Versal TSU clock cannot be disabled irrespective of whether PTP is

off clocks.
More information on this for future reference:
This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled
(See designcfg1, bit 3). However it is better to rely on an SoC specific
check rather than the IP version because tsu clk property itself may not
represent actual HW tsu clock on some chip designs.

Simplify the logic that selects bpf_prog_pack_size, and always use
(PMD_SIZE * num_possible_nodes()). This is a good tradeoff, as most of
the performance benefit observed is from less direct map fragmentation [0].
Also, module_alloc(4MB) may not allocate 4MB aligned memory. Therefore,
we cannot use (ptr & bpf_prog_pack_mask) to find the correct address of
bpf_prog_pack. Fix this by checking the header address falls in the range
of pack->ptr and (pack->ptr + bpf_prog_pack_size).

Currently we call the original function by using the absolute address
given at the JIT generation. That's not usable when having trampoline
attached to multiple functions, or the target address changes dynamically
(in case of live patch). In such cases we need to take the return address
from the stack.
Adding support to retrieve the original function address from the stack
by adding new BPF_TRAMP_F_ORIG_STACK flag for arch_prepare_bpf_trampoline
function.
Basically we take the return address of the 'fentry' call:
function + 0: call fentry # stores 'function + 5' address on stack
function + 5: ...
The 'function + 5' address will be used as the address for the
original function to call.

IPMODIFY (livepatch) and DIRECT (bpf trampoline) ops are both important
users of ftrace. It is necessary to allow them work on the same function
at the same time.
First, DIRECT ops no longer specify IPMODIFY flag. Instead, DIRECT flag is
handled together with IPMODIFY flag in __ftrace_hash_update_ipmodify().
Then, a callback function, ops_func, is added to ftrace_ops. This is used
by ftrace core code to understand whether the DIRECT ops can share with an
IPMODIFY ops. To share with IPMODIFY ops, the DIRECT ops need to implement
the callback function and adjust the direct trampoline accordingly.
If DIRECT ops is attached before the IPMODIFY ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_PEER on the DIRECT ops before registering the
IPMODIFY ops.
If IPMODIFY ops is attached before the DIRECT ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_SELF in __ftrace_hash_update_ipmodify. Owner of the
DIRECT ops may return 0 if the DIRECT trampoline can share with IPMODIFY,
so error code otherwise. The error code is propagated to
register_ftrace_direct_multi so that onwer of the DIRECT trampoline can
handle it properly.
For more details, please refer to comment before enum ftrace_ops_cmd.

This is similar to modify_ftrace_direct_multi, but does not acquire
direct_mutex. This is useful when direct_mutex is already locked by the
user.

The timed ending of Discoverability was handled in hci_requst.c, with
calls using the deprecated hci_req_add() mechanism. Converted to live
inside mgmt.c using the same delayed work queue, but with hci_sync
version of hci_update_discoverable().

This removes the remaining calls to HCI_OP_WRITE_SCAN_ENABLE from
hci_request call chains, and converts them to hci_sync calls.

The discov_update work queue is no longer used as a result
of the hci_sync rework.

This removes the use of hci_conn_hold from Get Conn Info and Get Clock
Info since the callback can just do a lookup by address using the cmd
data and only then set cmd->user_data to pass to the complete callback.
