The tx ring buffer map when xmit and unmap when xmit done. So in
hnae_init_ring() did not map tx ring buffer, but in hnae_fini_ring()
have a unmap operation for tx ring buffer, which is already unmapped
when xmit done, than cause this WARNING.
The hnae_alloc_buffers() is called in hnae_init_ring(),
so the hnae_free_buffers() should be in hnae_fini_ring(), not in
hnae_free_desc().
In hnae_fini_ring(), adds a check is_rx_ring() as in hnae_init_ring().
When the ring buffer is tx ring, adds a piece of code to ensure that
the tx ring is unmap.

When the HNS driver loaded, always have an error print:
"netif_napi_add() called with weight 256"
This is because the kernel checks the NAPI polling weights
requested by drivers and it prints an error message if a driver
requests a weight bigger than 64.
So use NAPI_POLL_WEIGHT to fix it.

This patch is trying to fix the issue due to:
[27237.844750] BUG: KASAN: use-after-free in hns_nic_net_xmit_hw+0x708/0xa18[hns_enet_drv]
After hnae_queue_xmit() in hns_nic_net_xmit_hw(), can be
interrupted by interruptions, and than call hns_nic_tx_poll_one()
to handle the new packets, and free the skb. So, when turn back to
hns_nic_net_xmit_hw(), calling skb->len will cause use-after-free.
This patch update tx ring statistics in hns_nic_tx_poll_one() to
fix the bug.

When the kdump kernel started, the HNS3 driver fail to register:

[14.795034] hns3 0000:7d:00.0: add uc mac address fail, ret =-22.
By default, the HNS3 driver will use about 512M memory, but
usually the reserved memory of kdump kernel is 576M, so the HNS3
driver fail to register. This patch reduces the memory use in
kdump kernel to about 16M.
And when the kdump kernel starts, we must clear ucast mac address
first to avoid add fail.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
size = struct_size(instance, entry, count);
or
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Based on the above, replace qtnf_cmd_acl_data_size() with the
new struct_size() helper.

$ btrfs prop set /btrfs compression zli
ERROR: failed to set compression for /btrfs: Invalid argument
$ btrfs prop get /btrfs compression
This is because the compression property ->validate() is successful for
'zli' as the strncmp() used the length passed from the userspace.

[Why]
the member sdr_white_level of struct dc_cursor_attributes was not
initialized, then the random value result that
dcn10_set_cursor_sdr_white_level() set error hw_scale value 0x20D9(normal
value is 0x3c00), this cause the black cursor issue.
[how]
just initilize the obj of struct dc_cursor_attributes to zero to avoid
the random value.

Since, ksym_search added with verification logic for symbols existence,
it could return NULL when the kernel symbols are not loaded.
This commit will add NULL check logic after ksym_search.

Currently, ksym_search located at trace_helpers won't check symbols are
existing or not.
In ksym_search, when symbol is not found, it will return &syms[0](_stext).
But when the kernel symbols are not loaded, it will return NULL, which is
not a desired action.
This commit will add verification logic whether symbols are loaded prior
to the symbol search.

We would never be able to sort the list if we first reset plug->rq_count

C-SKY syscall arguments are located in orig_a0,a1,a2,a3,regs[0],regs[1]
fields of struct pt_regs.
Due to an off-by-one bug and a bug in pointer arithmetic
syscall_get_arguments() was reading orig_a0,regs[1..5] fields instead.
Likewise, syscall_set_arguments() was writing orig_a0,regs[1..5] fields

The only users that calls syscall_get_arguments() with a variable and not a
hard coded '6' is ftrace_syscall_enter(). syscall_get_arguments() can be
optimized by removing a variable input, and always grabbing 6 arguments
regardless of what the system call actually uses.
Change ftrace_syscall_enter() to pass the 6 args into a local stack array
and copy the necessary arguments into the trace event as needed.
This is needed to remove two parameters from syscall_get_arguments().

task_current_syscall() has a single user that passes in 6 for maxargs, which
is the maximum arguments that can be used to get system calls from
syscall_get_arguments(). Instead of passing in a number of arguments to
grab, just get 6 arguments. The args argument even specifies that it's an
array of 6 items.
This will also allow changing syscall_get_arguments() to not get a variable
number of arguments, but always grab 6.
Linus also suggested not passing in a bunch of arguments to
task_current_syscall() but to instead pass in a pointer to a structure, and
just fill the structure. struct seccomp_data has almost all the parameters
that is needed except for the stack pointer (sp). As seccomp_data is part of
uapi, and I'm afraid to change it, a new structure was created
"syscall_info", which includes seccomp_data and adds the "sp" field.

He bisected it down to e332f741a8dd ("mm, compaction: be selective about
what pageblocks to clear skip hints"). The problem is that the patch in
question was sloppy with respect to the handling of zone boundaries. In
some instances, it was possible for PFNs outside of a zone to be examined
and if those were not properly initialised or poisoned then it would
trigger the VM_BUG_ON. This patch corrects the zone boundary issues when
resetting pageblock skip hints and Mikhail reported that the bug did not
trigger after 30 hours of testing.

Smatch complains that "local_rx_pd->priority" can't be trusted because
it comes from skb->data and it can go up to 255 instead of being capped

Clang warns about what is clearly a case of passing an uninitalized
variable into a static function:
drivers/net/wireless/broadcom/b43/phy_lp.c:1852:23: error: variable 'gains' is uninitialized when used here
[-Werror,-Wuninitialized]
lpphy_papd_cal(dev, gains, 0, 1, 30);
^~~~~
drivers/net/wireless/broadcom/b43/phy_lp.c:1838:2: note: variable 'gains' is declared here
struct lpphy_tx_gains gains, oldgains;
^
1 error generated.
However, this function is empty, and its arguments are never evaluated,
so gcc in contrast does not warn here. Both compilers behave in a
reasonable way as far as I can tell, so we should change the code
to avoid the warning everywhere.
We could just eliminate the lpphy_papd_cal() function entirely,
given that it has had the TODO comment in it for 10 years now
and is rather unlikely to ever get done. I'm doing a simpler
change here, and just pass the 'oldgains' variable in that has
been initialized, based on the guess that this is what was
originally meant.

Fix a race which leads to an Oops with NULL pointer dereference. The
dereference is in brcmf_config_dongle() when cfg_to_ndev() attempts to get
net_device structure of interface with index 0 via if2bss mapping. This
shouldn't fail because of check for bus being ready in brcmf_netdev_open(),
but it's not synchronised with USB disconnect and there is a race: after
the check the bus can be marked down and the mapping for interface 0 may be
gone.
Solve this by modifying disconnect handling so that the removal of mapping
of ifidx to brcmf_if structure happens after netdev removal (which is
synchronous with brcmf_netdev_open() thanks to rtln being locked in
devinet_ioctl()). This assures brcmf_netdev_open() returns before the
mapping is removed during disconnect.
