Enable Super speed plus in configfs to support USB3.1 Gen2.
This ensures that when a USB gadget is plugged in, it is
enumerated as Gen 2 and connected at 10 Gbps if the host and
cable are capable of it.
Many in-tree gadget functions (fs, midi, acm, ncm, mass_storage,
etc.) already have SuperSpeed Plus support.
Tested: plugged gadget into Linux host and saw:

It is observed 'use-after-free' on the dmabuf's file->f_inode with the
race between closing the dmabuf file and reading the dmabuf's debug
info.
Consider the below scenario where P1 is closing the dma_buf file
and P2 is reading the dma_buf's debug info in the system:
P1 P2
dma_buf_debug_show()
dma_buf_put()
__fput()
file->f_op->release()
dput()
....
dentry_unlink_inode()
iput(dentry->d_inode)
(where the inode is freed)
mutex_lock(&db_list.lock)
read 'dma_buf->file->f_inode'
(the same inode is freed by P1)
mutex_unlock(&db_list.lock)
dentry->d_op->d_release()-->
dma_buf_release()
.....
mutex_lock(&db_list.lock)
removes the dmabuf from the list
mutex_unlock(&db_list.lock)
In the above scenario, when dma_buf_put() is called on a dma_buf, it
first frees the dma_buf's file->f_inode(=dentry->d_inode) and then
removes this dma_buf from the system db_list. In between P2 traversing
the db_list tries to access this dma_buf's file->f_inode that was freed
by P1 which is a use-after-free case.
Since, __fput() calls f_op->release first and then later calls the
d_op->d_release, move the dma_buf's db_list removal from d_release() to
f_op->release(). This ensures that dma_buf's file->f_inode is not
accessed after it is released.

pointer in HW, then in driver
The previous patch fixes a TEF vs. TX race condition, by first updating the TEF
tail pointer in hardware, and then updating the driver internal pointer.
The same pattern exists in the RX-path, too. This should be no problem, as the
driver accesses the RX-FIFO from the interrupt handler only, thus the access is
properly serialized. Fix the order here, too, so that the TEF- and RX-path look
similar.

The mcp251xfd driver uses a TX FIFO for sending CAN frames and a TX Event FIFO
(TEF) for completed TX-requests.
The TEF event handling in the mcp251xfd_handle_tefif() function has a race
condition. It first increments the tx-ring's tail counter to signal that
there's room in the TX and TEF FIFO, then it increments the TEF FIFO in
hardware.
A running mcp251xfd_start_xmit() on a different CPU might not stop the txqueue
(as the tx-ring still shows free space). The next mcp251xfd_start_xmit() will
push a message into the chip and the TX complete event might overflow the TEF
FIFO.
This patch changes the order to fix the problem.

According to the TCAN4550 datasheet "SLLSF91 - DECEMBER 2018" the tcan4x5x has
the same bittiming constants as a m_can revision 3.2.x/3.3.0.
The tcan4x5x chip I'm using identifies itself as m_can revision 3.2.1, so
remove the tcan4x5x specific bittiming values and rely on the values in the
m_can driver, which are selected according to core revision.

For older glibc ~2.17, #include'ing both linux/if.h and net/if.h

^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
IFF_UP = 0x1, /* Interface is up. */
The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.
Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.

From Ard:
"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.
So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."
Disable support until the code can be properly refactored to support this
properly on aarch64.

This patch is to improve the fine grain tuning function for RV/RV2/PCO.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together. So this patch adds one flag to avoid this confusion, the flag
will make these two sysfs nodes work separately.
The flag is set as "disabled" by default, so the fine grain tuning function
will be disabled by default.
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag will be set as "enabled",
and the fine grain tuning function will be enabled.
In other profile modes, including "auto", "high", "low",
"profile_peak", "profile_standard", "profile_min_sclk",
"profile_min_mclk", the flag will be set as "disabled",
and the od range of fine grain tuning function will
be restored default value.

This patch is to improve the fine grain tuning function for RV/RV2/PCO.
This patch adds two new commands: "restore" and "commit".
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency manually or restore the default value.
Command guide:
echo "s level value" > pp_od_clk_voltage
"s" - set the sclk frequency
"level" - 0 or 1, "0" represents the min value, "1" represents
the max value
"value" - the target value of sclk frequency, it should be limited in the
safe range
echo "r" > pp_od_clk_voltage
"r" - reset the sclk frequency, restore the default value instantly
echo "c" > pp_od_clk_voltage
"c" - commit the min and max value of sclk frequency to the system
only after the commit command, the target values set by "s" command
will take effect.
Example:
1)change power profile from "auto" to "manual"
$ cat power_dpm_force_performance_level
auto
$ echo "manual" > power_dpm_force_performance_level
$ cat power_dpm_force_performance_level
manual
2)check the default sclk frequency
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
3)use "s" -- set command to configure the min and max sclk frequency
$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 600Mhz
1: 1000Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
4)use "r" -- reset command to restore the min or max sclk frequency
$ echo "r" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz

alloc_fixed_file_ref_node() currently returns an ERR_PTR on failure.
io_sqe_files_unregister() expects it to return NULL and since it can only
return -ENOMEM, it makes more sense to change alloc_fixed_file_ref_node()
to behave that way.

In mtrr_type_lookup(), if the input memory address region is not in the
MTRR, over 4GB, and not over the top of memory, a write-back attribute
is returned. These condition checks are for ensuring the input memory
address region is actually mapped to the physical memory.
However, if the end address is just aligned with the top of memory,
the condition check treats the address is over the top of memory, and
write-back attribute is not returned.
And this hits in a real use case with NVDIMM: the nd_pmem module tries
to map NVDIMMs as cacheable memories when NVDIMMs are connected. If a
NVDIMM is the last of the DIMMs, the performance of this NVDIMM becomes
very low since it is aligned with the top of memory and its memory type
is uncached-minus.
Move the input end address change to inclusive up into
mtrr_type_lookup(), before checking for the top of memory in either
mtrr_type_lookup_{variable,fixed}() helpers.

builds, where there is a orphan section warning then build failure:

When a queue is in NVMET_RDMA_Q_CONNECTING state, it may has some
requests at rsp_wait_list. In case a disconnect occurs at this
state, no one will empty this list and will return the requests to
free_rsps list. Normally nvmet_rdma_queue_established() free those
requests after moving the queue to NVMET_RDMA_Q_LIVE state, but in
this case __nvmet_rdma_queue_disconnect() is called before. The
crash happens at nvmet_rdma_free_rsps() when calling
list_del(&rsp->free_list), because the request exists only at
the wait list. To fix the issue, simply clear rsp_wait_list when
destroying the queue.

While handling the completion queue, keep a local copy of the command id
from the DMA-accessible completion entry. This silences a time-of-check
to time-of-use (TOCTOU) warning from KF/x[1], with respect to a
Thunderclap[2] vulnerability analysis. The double-read impact appears
benign.
There may be a theoretical window for @command_id to be used as an
adversary-controlled array-index-value for mounting a speculative
execution attack, but that mitigation is saved for a potential follow-on.
A man-in-the-middle attack on the data payload is out of scope for this
analysis and is hopefully mitigated by filesystem integrity mechanisms.

We may send a request (with or without its data) from two paths:
1. From our I/O context nvme_tcp_io_work which is triggered from:
- queue_rq
- r2t reception
- socket data_ready and write_space callbacks
2. Directly from queue_rq if the send_list is empty (because we want to
save the context switch associated with scheduling our io_work).
However, given that now we have the send_mutex, we may run into a race
condition where none of these contexts will send the pending payload to
the controller. Both io_work send path and queue_rq send path
opportunistically attempt to acquire the send_mutex however queue_rq only
attempts to send a single request, and if io_work context fails to
acquire the send_mutex it will complete without rescheduling itself.
The race can trigger with the following sequence:
1. queue_rq sends request (no incapsule data) and blocks
2. RX path receives r2t - prepares data PDU to send, adds h2cdata PDU
to the send_list and schedules io_work
3. io_work triggers and cannot acquire the send_mutex - because of (1),
ends without self rescheduling
4. queue_rq completes the send, and completes
==> no context will send the h2cdata - timeout.
Fix this by having queue_rq sending as much as it can from the send_list
such that if it still has any left, its because the socket buffer is
full and the socket write_space callback will trigger, thus guaranteeing
that a context will be scheduled to send the h2cdata PDU.
Fixes: db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq context")

A system with more than one of these SSDs will only have one usable.
Hence the kernel fails to detect nvme devices due to duplicate cntlids.
[ 6.274554] nvme nvme1: Duplicate cntlid 33 with nvme0, rejecting
[ 6.274566] nvme nvme1: Removing after probe failure status: -22
Adding the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk to resolves the issue.
