When CONFIG_MODULE_REL_CRCS is enabled, the value of __crc_* is not
an absolute value, but the address to the CRC data embedded in the
.rodata section.
Getting the data pointed by the symbol value is somewhat complex.
Split it out into a new helper, sym_get_data().
I will reuse it to refactor namespace_from_kstrtabns() in the next
commit.

If there's no traffic on a channel, its ARFS expiry work will never get
scheduled by efx_poll() as that isn't being run.
So make efx_filter_rfs_expire() reschedule itself to run after 30 seconds.

In high connection count usage, the NIC's filter table may be filled with
sufficiently many ARFS filters that further insertions fail. As this
does not represent a correctness issue, do not log the resulting MCDI
errors. Add a debug-level message under the (by default disabled)
rx_status category instead; and take the opportunity to do a little extra
expiry work.
Since there are now multiple workitems able to call __efx_filter_rfs_expire
on a given channel, it is possible for them to race and thus pass quotas
which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop
all the way around the table with quota left over.

The old rfs_filters_added method for determining the quota could potentially
allow the NIC to become filled with old filters, which never get tested for
expiry. Instead, explicitly make expiry check work depend on the number of
filters installed, and don't count checking slots without filters in as
doing work. This guarantees that each filter will be checked for expiry at
least once every thirty seconds (assuming the channel to which it belongs is
NAPI polling actively) regardless of fill level.

Jeff Kirsher says:
====================
This series contains updates to the ice driver only.
Bruce updates the driver to store the number of functions the device has
so that it won't have to compute it when setting safe mode capabilities.
Adds a check to adjust the reporting of capabilities for devices with
more than 4 ports, which differ for devices with less than 4 ports.
Brett adds a helper function to determine if the VF is allowed to do
VLAN operations based on the host's VF configuration. Also adds a new
function that initializes VLAN stripping (enabled/disabled) for the VF
based on the device supported capabilities. Adds a check if the vector
index is valid with the respect to the number of transmit and receive
queues configured when we set coalesce settings for DCB. Adds a check
if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX
so that VLAN 0 promiscuous rules to be removed. Add a helper macro for
a commonly used de-reference of a pointer to &pf->dev->pdev.
Jesse fixes an issue where if an invalid virtchnl request from the VF,
the driver would return uninitialized data to the VF from the PF stack,
so ensure the stack variable is initialized earlier. Add helpers to the
virtchnl interface make the reporting of strings consistent and help
reduce stack space. Implements VF statistics gathering via the kernel
ndo_get_vf_stats().
Akeem ensures we disable the state flag for each VF when its resources
are returned to the device.
Tony does additional cleanup in the driver to ensure the when we
allocate and free memory within the same function, we should not be
using devm_* variants; use regular alloc and free functions.
Henry implements code to query and set the number of channels on the
primary VSI for a PF via ethtool.
Jake cleans up needless NULL checks in ice_sched_cleanup_all().
Kevin updates the firmware API version to align with current NVM images.
v2: Added "Fixes:" tag to patch 5 commit description and added the use
of netif_is_rxfh_configured() in patch 13 to see if RSS has been
configured by the user, if so do not overwrite that configuration.

Currently, a lot of memory is wasted for architectures like MIPS when
init_ftrace_syscalls() allocates the array for syscalls using kcalloc.
This is because syscalls numbers start from 4000, 5000 or 6000 and
array elements up to that point are unused.
Fix this by using a data structure more suited to storing sparsely
populated arrays. The XARRAY data structure, implemented using radix
trees, is much more memory efficient for storing the syscalls in
question.

The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO)
requests expects the headers to be part of the descriptor and the
payload to be part of the SGL containing the DMA mapped addresses.
Hence, the DMA address in the first entry of the SGL can start after
the packet headers. Currently, unmap_sgl() tries to unmap from this
wrong offset, instead of the originally mapped DMA address.
So, use existing unmap_skb() instead, which takes originally saved DMA
addresses as input. Update all necessary Tx paths to save the original
DMA addresses, so that unmap_skb() can unmap them properly.

Newly introduced APIs used here -
1. Create/Lookup a trace array with the given name.
struct trace_array *trace_array_get_by_name(const char *name)
2. Destroy/Remove a trace array.
int trace_array_destroy(struct trace_array *tr)
4. Enable/Disable trace events:
int trace_array_set_clr_event(struct trace_array *tr, const char *system,
const char *event, bool enable);
Exported APIs -
1. trace_printk equivalent for instances.
int trace_array_printk(struct trace_array *tr,
unsigned long ip, const char *fmt, ...);
2. Helper function.
void trace_printk_init_buffers(void);
3. To decrement the reference counter.
void trace_array_put(struct trace_array *tr)

Add common clock driver for Bitmain BM1880 SoC. The clock controller on
BM1880 has supplies clocks to all peripherals in the form of gate clocks
and composite clocks (fixed factor + gate).

The clk_init_data struct needs to be initialized to zero for the new
parent_map implementation to work correctly. Otherwise, the member which
is available first will get processed.

This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.
Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
works perfectly fine on the X1 Extreme Gen 2 except for one thing I
didn't notice because I usually use the trackpoint: clicking with the
touchpad. Somehow this is broken, in fact we don't even seem to indicate
BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
see any RMI4 events coming from the touchpad when I press down on it.
This only seems to work for PS/2 mode.
Since that means we have a regression, and PS/2 mode seems to work fine
for the time being - revert this for now. We'll have to do a more
thorough investigation on this.

By default s_maxbytes is set to MAX_NON_LFS, which limits the usable
file size to 2GB, enforced by the vfs.
Commit b9b1f8d5930a ("AFS: write support fixes") added support for the
64-bit fetch and store server operations, but did not change this value.
As a result, attempts to write past the 2G mark result in EFBIG errors:
$ dd if=/dev/zero of=foo bs=1M count=1 seek=2048
dd: error writing 'foo': File too large
Set s_maxbytes to MAX_LFS_FILESIZE.

Servers sending callback breaks to the YFS_CM_SERVICE service may
send up to YFSCBMAX (1024) fids in a single RPC. Anything over
AFSCBMAX (50) will cause the assert in afs_break_callbacks to trigger.
Remove the assert, as the count has already been checked against
the appropriate max values in afs_deliver_cb_callback and
afs_deliver_yfs_cb_callback.

JZ4760/JZ4770/JZ4775/X1000/X1500 has an abandoned huge page tlb,
this mode is not compatible with the MIPS standard, it will cause
tlbmiss and into an infinite loop (line 21 in the tlb-funcs.S)
when starting the init process. write 0xa9000000 to cp0 register 5
sel 4 to disable this function to prevent getting stuck. Confirmed
by Ingenic, this operation will not adversely affect processors
without HPTLB function.

The code in ice_sched_cleanup_all checks whether the port info is NULL
prior to calling ice_sched_clear_port. However, ice_sched_clear_port
already checks whether port info is non-NULL.
More importantly, it also checks whether the port structure has been
initialized by checking its port_state field as well.
