The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_devices from struct mt76_dev by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev_dummy() to allocate the net_device object at
mt76_dma_init().
The free of the device occurs at mt76_dma_cleanup().

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

In the current code, if multiple hardware breakpoints/watchpoints in
a user-space thread, some of them will not be triggered.
When debugging the following code using gdb.
lihui@bogon:~$ cat test.c
#include <stdio.h>
int a = 0;
int main()
{
printf("start test\n");
a = 1;
printf("a = %d\n", a);
printf("end test\n");
return 0;
}
lihui@bogon:~$ gcc -g test.c -o test
lihui@bogon:~$ gdb test

(gdb) watch a
Hardware watchpoint 2: a

(gdb) c
Continuing.
start test
a = 1
Breakpoint 3, main () at test.c:8
8 printf("end test\n");
...
The first hardware watchpoint is not triggered, the root causes are:
1. In hw_breakpoint_control(), The FWPnCFG1.2.4/MWPnCFG1.2.4 register
settings are not distinguished. They should be set based on hardware
watchpoint functions (fetch or load/store operations).
2. In breakpoint_handler() and watchpoint_handler(), it doesn't identify
which watchpoint is triggered. So, all watchpoint-related perf_event
callbacks are called and siginfo is sent to the user space. This will
cause user-space unable to determine which watchpoint is triggered.
The kernel need to identity which watchpoint is triggered via MWPS/
FWPS registers, and then call the corresponding perf event callbacks
to report siginfo to the user-space.
Modify the relevant code to solve above issues.

In the current code, gdb can set the watchpoint successfully through
ptrace interface, but watchpoint will not be triggered.
When debugging the following code using gdb.
lihui@bogon:~$ cat test.c
#include <stdio.h>
int a = 0;
int main()
{
a = 1;
printf("a = %d\n", a);
return 0;

[Inferior 1 (process 4650) exited normally]
No watchpoints were triggered, the root causes are:
1. Kernel uses perf_event and hw_breakpoint framework to control
watchpoint, but the perf_event corresponding to watchpoint is
not enabled. So it needs to be enabled according to MWPnCFG3
or FWPnCFG3 PLV bit field in ptrace_hbp_set_ctrl(), and privilege
is set according to the monitored addr in hw_breakpoint_control().
Furthermore, add a judgment in ptrace_hbp_set_addr() to ensure
kernel-space addr cannot be monitored in user mode.
2. The global enable control for all watchpoints is the WE bit of
CSR.CRMD, and hardware sets the value to 0 when an exception is
triggered. When the ERTN instruction is executed to return, the
hardware restores the value of the PWE field of CSR.PRMD here.
So, before a thread containing watchpoints be scheduled, the PWE
field of CSR.PRMD needs to be set to 1. Add this modification in
hw_breakpoint_control().

Invalid argument setting hardware debug registers
There are mainly two types of issues.
1. Some incorrect judgment condition existed in user_watch_state
argument parsing, causing -EINVAL to be returned.
When setting up a watchpoint, gdb uses the ptrace interface,
ptrace(PTRACE_SETREGSET, tid, NT_LOONGARCH_HW_WATCH, (void *) &iov)).
Register values in user_watch_state as follows:
addr[0] = 0x0, mask[0] = 0x0, ctrl[0] = 0x0
addr[1] = 0x0, mask[1] = 0x0, ctrl[1] = 0x0
addr[2] = 0x0, mask[2] = 0x0, ctrl[2] = 0x0
addr[3] = 0x0, mask[3] = 0x0, ctrl[3] = 0x0
addr[4] = 0x0, mask[4] = 0x0, ctrl[4] = 0x0
addr[5] = 0x0, mask[5] = 0x0, ctrl[5] = 0x0
addr[6] = 0x0, mask[6] = 0x0, ctrl[6] = 0x0
addr[7] = 0x12000803c, mask[7] = 0x0, ctrl[7] = 0x610
In arch_bp_generic_fields(), return -EINVAL when ctrl.len is
LOONGARCH_BREAKPOINT_LEN_8(0b00). So delete the incorrect judgment here.
In ptrace_hbp_fill_attr_ctrl(), when note_type is NT_LOONGARCH_HW_WATCH
and ctrl[0] == 0x0, if ((type & HW_BREAKPOINT_RW) != type) will return
-EINVAL. Here ctrl.type should be set based on note_type, and unnecessary
judgments can be removed.
2. The watchpoint argument was not set correctly due to unnecessary
offset and alignment_mask.
Modify ptrace_hbp_fill_attr_ctrl() and hw_breakpoint_arch_parse(), which
ensure the watchpont argument is set correctly.

GAS <= 2.41 does not support generating R_LARCH_{32,64}_PCREL for
"label - ." and it generates R_LARCH_{ADD,SUB}{32,64} pairs instead.
Objtool cannot handle R_LARCH_{ADD,SUB}{32,64} pair in __jump_table
(static key implementation) and etc. so it will produce some warnings.
This is causing the kernel CI systems to complain everywhere.
For GAS we can check if -mthin-add-sub option is available to know if
R_LARCH_{32,64}_PCREL are supported.
For Clang, we require Clang >= 18 and Clang >= 17 already supports
R_LARCH_{32,64}_PCREL. But unfortunately Clang has some other issues,
so we disable objtool for Clang at present.
Note that __jump_table here is not generated by the compiler, so
-fno-jump-table is completely irrelevant for this issue.
